Topic: Antminer S19 95TH setup (Read 884 times)

Can i use a l6-30p to dual c13 directly ? Like this?  https://a.co/d/29LCoZj

Or is it better to split after the c19?


Also, i bought the mentionned antminer s19j pro... But on the miner i received, the sticker say s19 Pro... without the J ...

Hopefully the cord that came with it has the proper plug for your country - the US, Asia and rest of the world all use different styles of power outlets & plugs... The end that plugs into the miner is the one *standard* connector they all use.

Thanks for your quick reply, realy appreciated. Should have started here for informations.

A PDU is only for if you want to switch or otherwise control/monitor several miners. For one miner just plug it into a 208-240V 20A receptacle.

Hi! Is a pdu needed, or usefull ? Like this?: https://www.amazon.ca/dp/B00ZPOIPO4?ref=ppx_yo2ov_dt_b_product_details&th=1

Btw, I will not be using the same model, but a s19j pro 100TH wich say 3050W.

Maybe I am doing this all wrong 

Hi again,

I understand that you do not know this provider, so, if I buy a miner, I will buy it from viperatech. They have the best conditions till now.
I am a bit on the fence though. I understood that there are only 5 month till the next halving, and in the present situation I would have some 140$ profit per month, if the pool fee is 2%, so I would get my investment (the price of the miner) back in a year or so, however after the halving what is it going to be? I imagine that the profit will go half, so some 70$ per month. And I have to deal with the noise and heat.
Therefore comes the question, in the long run is it worth it? Or I would have just another doodad?

Thank you for your thoughts

Hi guys,

Did anybody hear of this company/provider of ASICs? https://captainmining.com/
I checked them out, the prices are good, however I did not find any review about it.

Thank you

Thank you very much seek3r.
I will have to document and educate myself further on. Probably I will try the antpool as with ViaBTC it went with a lot of difficulty. I made in almost 2 weeks mining with 63TH only 0.00052172 BTC.
I also have to figure out, when it will get warmer outside, what to do with all the heat in the basement, and of course the noise. So, I have a lot of research to do.
Thank you again, and I will highly appreciate any other views/info about this issue of mine, as always.
I appreciate a lot this forum for the fountain of knowledge and professionalism.
May the BTC be with you

Sorry. I didn't express myself clearly there. What was meant were the telephone numbers. But it looks like you've already talked to them.

That all sounds great and makes a good impression. It certainly doesn't hurt if you find a dealer who will give you advice and support and isn't just concerned about selling as many units as possible.

And ofc paying 2% on fee less is better for ur own pocket/wallet. At the end you have to see which form of pool is best for you as there are also different reward types (PPS, PPLNS and so on).

Thank you for your response seek3r.
What do you mean by "numbers stored on their website"?
I found about them as I was "digging" for info regarding mining and miners, and they were very, very helpful with all the advice they gave me. They told me about the 220V and how to get it (I got it like they said). They told me about pools, however that info I did not get it vetted yet. They said something about antpool and braiins that they should be better with the 2% fee compared to the 4% from ViaBTC.
Also I asked them a lot of questions lately, and they took care of them properly.

First of all: Great to hear that u got almost all of ur funds back from ur previous machine which caused a lot of trouble.

Keep in mind that BTC is a notoriously volatile market. The profitability of mining can change rapidly with fluctuations in the price of Bitcoin.

They offer a Warranty called "CYCLESAFE" - you should find all the information about it here: https://www.viperatech.com/cyclesafe-warranty/
2 year warranty sounds nice in the first thought but always make sure to doublecheck what will be covered from that.

Other than that, it certainly doesn't sound bad. There are also numbers stored on their website. It certainly doesn't hurt to get in touch and express your interest.
You often get an idea of ​​how legit they really are.

Hi guys,
I think I might take advantage of the offer from vipera tech: https://www.viperatech.com/product/bitmain-antminer-s19k-pro-136th-s/?currency=CAD
It is an Antminer S19k pro, and from what I understood it should be a solid machine, and from what I estimated, with the 120T machine I should have a nice profit from mining.
In the end I managed to get the refund from the previous machine, at least some 80%, because they deducted 20% restocking fee.
I checked with vipera tech all the conditions and they seem fair enough. They also offer a 2 year warranty. I am checking with them now what is included in this warranty.
Any thoughts?
Thank you

I found in Canada Viperatech in Montreal and they have very nice prices. Their customer service is also very helpful.
https://www.viperatech.com/
They are also present in the US.

Thank you very much Seek3r.
May the BTC be with you

Not from Canada nor US so I dont have a personal experience.
But you might want to check out https://www.gdsupplies.ca/ which I found. Also found out that QuoteColo offers hosting colocations and could help you.
They are offering fully managed mining so they should be able to help you with repair requests and so on.

Hi philipma1957,

Thank you very much for the links, however  I am in Ontario, Canada, so I would use these links if they also have a branch/associate in Canada, or, if not, as a last resort in case I do not find anything suitable in Canada. Right now I have Vipera Canada who helped me with some other noob issues that I had, before discovering your forum.

Have a great day, and may the BTC be with you 

https://vmssecuritycloud.com/

is in Long Island New York.  Greg is the owner. tell him I sent you to his website.

He handles repairs. I have physically been to his shop.

https://vmssecuritycloud.com/product/bitmain-s19-95t-antminer/

If you are on the East Coast he is good for you.

https://altairtech.io/ is in Missouri he is good. for gear parts and accessories .

not sure about repair as I use VMS

Regarding the price of KWh, what you said about 0.10 is USD, right? Then, I might still have a chance, as right now, in Canada, the price is still underneath that threshold, so I should be OK with a "normal" miner.
Also, regarding the USB miner, I understood that it does not work so well under Windows, so I should use a Raspberry Pi which would increase my cost again over 1000 $, so I think I would stick to the Antminer, or Canaan, if I find a suitable one.
Thank you for the info

I tried what you said using the USB miner from Gekkoscience, however the videos I watched showed that there is no win even with 3 of them, so I do not know how this would be a good idea after all.
Thank you for it anyways.
Actually, I would not mind if I would acquire BTC a bit more expensive using mining, for instance for the same power double the TH/s. The problem I would have right now would be the heat that is generated by it, and the noise. So I will think about this also.
Is there anywhere a calculation page where I could at least estimate what would be the loss, i.e. how much I would have to pay for the BTC?
Thank you

Your #1 issue is the cost of power. Anything over $0.10/kW/H will NOT be able to mine at a profit. Period. No miner will ever be able to be efficient enough to do that.

Now if BTC goes over $50k again then ja that could work.

Your only option is to use a USB miner like Sidehack's R909, pulls less than 100w for over 1.5TH. Use something like that and point it at a solo pool like Kano's or -ck's as a lottery miner. Dirt cheap to run and if it finds a block you get the entire reward.

Unfortunately, Amazon dismissed my claims, probably because this seller QIO TECH is moving a lot of product through them, on very weird/obscure reasons, so I had to escalate the issue, and I hope this will be dealt with in a positive manner. I told Amazon that it seems to me that it is not customer-service, but seller-service, no?
I do not understand, all manufacturers/sellers of bitcoin mining machines are that devious/weird from the customer service point of view? I had another issue with a USB miner that I sent back, and though I just opened the package, looked at whatever was inside, put them back in as they were packed, and closed the package, they dismissed this refund for the reason that "the content was not the same as originally packed". What?!
Amazon said they will take care if this one, however the one from QIO TECH, instead of sending it to HongKong, I will send it to a Quebec address supplied by the seller, where it is much cheaper, and Amazon said they will take care of the restocking fees. We will see how it goes.
However, this type of treatment of the customers that want to mine and use their mining machines, is not too positive. I was expecting them to be in the same way as the Bitcoin crowd, to be able to make a difference. Instead of shi..ing on the little man/customer, to treat him/her with respect.
Anyways, in the end the idea of mining is still appealing to me, however I would like to do it in a more profitable way, i.e. a faster machine eating less power, if possible, and I would need eventually, if you know, some suppliers that you eventually dealt with, or know that they still have integrity when dealing with customers, it would be great.
I was looking at www.viperatech.com/ and they have a lot of mining machines, however I do not know which one to pick. I know they are close to here, however I do not know how they are in terms of customer service...
If you would know some other sellers that have more some backbone as companies that sell miners, I would highly appreciate the info.
Thank you

Thank you for your response, and I understand your message.
I was looking actually, if I could get one with a price that is accessible to me, for a machine that does not need so much electric power (right now the price for KWh in Ontario is pretty high), and has a higher speed, TH/s. If you could tell me a source where I could get one, it would be great.
I was looking by myself for machines, and do not understand why machines for BTC mining are most of them produced in China, though China is prohibiting the ownership of BTC... However this is because I am still a noob...
Have a great day

The hashrate of each miner is subjective, it has everything to do with the algorithm it works on, in other words, a car that does 50km/h competing against 20 old men on wheelchairs is certainly a lot slower than a car that does 300km/h, but when latter is competing against a dozen ballistic missiles, the slow car is "better".

So ya, don't compare different miners from different algorithms, there could exist a miner with the speed of a few mega hashes that makes more "money" than a truckload of the fastest Sha256 miners, but you need to keep in mind the future competition, SHA256 difficulty is hard to move, 5% is considered a lot, whereby the overall difficulty of other smaller algorithms could easily double in a few days, so ya, there is more to it than meets the eye.

Sorry, I did not see that actually it was KH, and not TH. My bad.
I keep looking.
Do you have a good source that I could take into consideration?
Thank you.

Considering this area is for Bitcoin only you need to ask about altcoin (aka crap coin) hardware in the altcoin area like here

As for Not counting the fact that they are entirely different algorithms, in what world is 212KH/s faster than 95TH/s....

Hi guys,
I was actually thinking to buy a more performant miner, for instance the Bitmain Antminer X5 212KH/s 1350W (XMR)
What are your thoughts about it? The power is lower than the S19 95TH, and the speed is more than double.
Is there any way of calculating how profitable this machine would be?
Thank you

Thank you very much for the info Dave.
I will surely use this bit of info when I will talk to Amazon customer service.
What is very interesting though is that if you look at the page offering this miner on Amazon, there is also an offer for a "not new" miner, and it is some 250$ cheaper, so this would be a refurb of the refurb?
Weird. Normally, these type of miners should not be in sale anymore because, like it was for me, the cost of electric power in Ontario is forbidding the mining with those machines. The cost of power per day would be like 6.5$, and I managed to make almost 12$ in 3 days. If I would have had this info before purchasing this machine, I would have either bought a more powerful one, or not at all.
The issue was, in my situation, that the information on the https://www.bitcoinmining.com/ is very, very dated, and nobody thought of updating it with newer data. I was fortunate enough to find your forum, and this is when the lights finally went on. It would be nice, instead of all this useless info (like using USB miners that are nowadays a joke), to simply have a link to your forum where there is true shared experience, which I highly appreciated.
Thank you again to all who helped me till now, and happy mining! It seems that that ship sailed away for me, at least for the time being. I am thinking of alternatives.

The miner was not new, there have not been new S19 95TH out there for a while.
Lightly used / refurbished perhaps. But, not new.
Just saying this because if the seller / Amazon decide to give you a hassle about the return (doubtful since Amazon is very good with this) you could probably use that to help with getting your money back.

-Dave

Sincerely, when I began thinking about starting to mine, I wanted to make bitcoin, but also to contribute to the consensus that is still in the blockchain and keep it as Satoshi intended to have it. However, due to the subtle, and not so subtle, regulations that the existing fiat system introduced (regulation of companies dealing with crypto, the increasing of the price for electricity), the "true" mining becomes more and more difficult for those who truly want to maintain the original idea that the cypherpunks tried to implement. Unfortunately, the blockchain is more and more in the hands of people/companies with means that can afford the high electricity prices, and high machine prices. Machines like mine should be prohibited as they work in the disadvantage of the miner, or if they are left to be used, eventually encourage the mining with some incentives, probably from the mining pool side. Otherwise there will remain only the ones with means, that sometimes nobody knows if they eventually don't work for the fiat system (government, banks), and if the issue with the 51% comes into being, than the bitcoin will become just like any other fiat money.
I admit that I did not document myself too well before purchasing this machine, because otherwise I would either have bought a stronger one, or not at all, but I was enthused by the idea of bitcoin and the mining of it that I did not think of such a calculation. I assumed, and that was my mistake.
Unfortunately, I did not come to a complete agreement with the seller of the machine who tries to give me less than the price I payed for, invoking all kinds of reasons. They have very poor customer service, and I hope that Amazon will solve the issue somehow in my favour.
Therefore be warned, the QIO TECH company based in ShenZhen is very nice with you if the machine is working, however if you have not such a good luck, like me, they will invoke all kinds of reasons for not reimbursing you. It is sad that this is called "customer service". It is more like "company service" not caring too much about the customer.
So pray for me that I will see my money back from them.
Thank you again for all the support. You are a great team, a true spirit of the bitcoin idea of Satoshi Nakamoto.

It's great that you arrived at this conclusion in a very short period, the "short calculation" should have been done prior to purchasing the miner, you are lucky that you managed to return the miner -- most would have to sell it at a loss or use it as a doorstopper.

Being heavily involved in the mining industry makes it difficult for us to see how non-miners are so misled into thinking that bitcoin mining is profitable to everyone, most people don't even know how much their miner will consume, and not everyone is as brave as you are to admit their mistake, everyone who wants to start mining bitcoin should spend at least a week reading the different topics in this forum, they will get 90% of the information which would help them decide before investing a single dollar.

Hi guys,
After the whole discussion with the seller's and Amazon's customer services, I decided to return the miner.
Also, after making a short calculation, due to increasing electric energy prices in ON, the mining of BTC using this miner is loosing money. The miner is consuming some 10$/day, and I barely made 8$ in 2 days.
So, I am sorry to have to leave this community I was beginning to enjoy so much.
Thank you very much for your support guys!

Thank you very much MitMaxz for your reply.
I did not try to swap the cables. I just reseated them, i.e. unplugged/plugged them back where they were, and it did not make any difference.
I will try eventually to do what you say, however I would like to send the unit to be repaired as soon as possible, i.e. today, so that I can have it back as soon as possible.
Have a great day

I hope that you try checking the cable first by switching to another hashboard to confirm if it is just a cable or clean the copper bar with sandpaper as I suggested in my previous post but the sad part you end up sending it for repair.

Next time do some troubleshooting first before sending it for repair because sending it back for repair had a shipping cost.

Anyway, I'd like to give you a link that you can use for troubleshooting in the future and I hope it will be useful in the future if you experience some issues listed from the link below.

Hi Dave,
I talked to Larry from customer service and after all the things he suggested I do (I reseated the connectors that are underneath the above lid, upgraded the firmware, and restarted the miner), there were still 2 boards. Number 1 was still not available.
So now I have to send the Antminer across the country to Richmondhill, BC for repairs.
It looks a bit wrong as I have a brand new product that will become a "repaired" product that actually does not have the same value as the brand new one. He offered 80$ for the loss I would have in mining till the miner will be back from repairs. I am not too happy about the whole outcome, however if I talk to Amazon, I guess they will stick to the seller, and I will get my money back, if I get it back, in 30 days.
So I will send the miner for repairs in the end, and see what becomes from that.
I will call Amazon just to see what they say, however I am a bit disappointed in how they solve such issue.

They sent me a video on how to remove the upper housing to check the contacts for the connectors.
I am going to do that, and if it does not solve the issue, I hope they will send me another miner. Till now they were very friendly.
I hope it is a loose contact due to the transportation. It worked for a short while, and I had awesome hash rates, but very short.
In case they try to pull my leg, I will involve Amazon soon enough.
Thank you

Could be the power bar, could be the cable.
I would wait to hear back from the seller.
Here in *theory* taking it apart and checking the cables should not invalidate the warranty since you do have to pull miners apart now and then to clean out the dust.
In reality, since you bought it from a reseller through Amazon, they can make any rules they want about what you can and cannot do. I would wait to see what they say.

If they don't respond or fix it for you get Amazon involved as early in the process as possible.

-Dave

Hi BitMaxz,
Thank you for the offer. The only think about checking the contacts, I do not know how to do that w/o voiding the warranty, OK?

Can you share your miner logs I just want to check the logs if the 1st hashboard is still detected while it's not running properly we can maybe find the issue under the logs and give you some suggestions to try.

I guess that the 1st hashboard might had poor contact with the copper bar cleaning it with sandpaper might solve this.

Hi philipma1957,
I already did that 2 times, hoping what you were suggesting, and every time only 2 boards appeared, 2 & 3. Number 1 is not appearing.
Prior to my first restart, on the GUI, as I saw the hash rate dropping, I checked the boards and number 1 appeared in red with 0 hash. After I restarted the unit the first time, the board #1 did not appear anymore. Only 2 & 3.
It could be, as Dave suggested, that a contact got loose during the transportation, however I am reluctant of opening up the unit as this might void the warranty, so I am waiting for customer support to respond to my messages, and take it from there.
Thank you

try to restart it maybe it will go back to 3 boards.

Sometimes it is just a glitch and not a bad board.

Thank you Dave,
I am letting it run for the time being, and I am waiting for a response from the customer service of the seller. I got this from Amazon, and the seller is QIO TECH, so I am a bit reluctant to open it up to check what you were suggesting. It could be that there is a loose contact from transportation, however it would also void the warranty, right?
I will see what they respond, and I hope they have someone local that would take care of repairing the unit, otherwise I would have to send it back to China, and wait for a resolution...
Eventually, according to how the warranty process is working with them, I would send it back for a full refund, and I will see if I purchase a new one.
I will see first how they respond, and what their warranty response is.
Have a great day

Just let it run. If the board is not hashing it's not pulling power so it's not like it costs more power to have it just sit there. You are just loosing profit.

You can try making sure the cables from the controller are in all the way and a full power down and cool off cycle and see if that fixes it, but since you do have a warranty I would just get a new miner.

Hi Dave,
You are right. I checked on the UI on the browser, and initially it showed hash board 1 not working, and I did a restart from the UI.
After it restarted, it showed only board 2 and 3.
Yes, I have warranty on the unit. So should I let it running with just 2 boards, or should I turn it off.
If I have to turn it off, should I just click on the restart miner button, and then un plug it? Or simply unplug it?
Thank you

It sounds like one of your hashboards died. There are 3 each doing a bit over 30TH so dropping to the 60s really sounds like one of them just stopped working.
What does the web gui show for the boards? Also post the debug log if possible.

Did you get any kind of warranty on the unit? If you did, it might just be easier to send it back for a different one then spend time troubleshooting the problem.

-Dave

Hi guys,
I managed today to turn on my Antminer S19 95TH, and it is working!!! An electrician helped me with a 220V line, so from this point of view everything is nice and dandy.
I was so excited to see the hashrate going to 96T, however, after a while, it went to 64, and then to 62, and it is still oscillating between those two.
Can I do anything? Did I configure it wrongly?
I already took contact with ViaBTC to see what is going on, and I am waiting for their response.
The miner is very noisy, and the basement is getting pretty warm now. It is good that we are approaching winter, so it will be good.
Thank you

Thank you very much

This unit does not have a switch or button to turn it off this unit you just simply unplug the unit from the power source.

Or you can use the reboot button from the dashboard you can find it under the system and then once the unit LED light turns off unplug the unit from power source.

So,
Is there a specific procedure to turn off an Antminer S19 for cleaning or for replacing network cables? Or simply unplug the power cords would be enough?
Thank you

Hi all,

Right now I am about to set the combinations of cables that philipma1957 sent me, and configure my antminer.
I would have another question though. I let's say I want to have a cabling solution involving an electrician, and later on I will switch to that solution, what are the proper steps to take the antminer down and plug it into the other cabling solution?
Do I have to follow a specific procedure, succession of steps, or just unplugging it should be enough?

Thank you

Thank you very much. I managed to increase the speed to 20Mbps, so I think I am good.
Have a great weekend.

If you are running one unit 10mbps should be beyond enough the important is the internet you provide to the unit is should stable and use a pool server that gives you low latency like if you are in the US then use the US pool server or if you are living in Asian country then use Asia pool server.

Thank you very much for the information.
I could pull a cable from the router (2nd level) to the miner (basement), however it will be through the house, and it would not be practical.
I could also pull it through the air ducts, however I need help, which I do not have right now.
I checked the speed and it is 10Mbps, and, from what I understood that the server would need some 5Mbps, it should be enough no?
Thank you

There is a simple formula which is provided by Bitmain support:
Source: https://support.bitmain.com/hc/en-us/articles/5291909784601-Network-Bandwidth-and-Load#:~:text=The%20formula%20for%20calculating%20the,of%20servers%20(sets)%2F150.

Since you are using one unit the required bandwidth is less than 1Mbps.

Regarding ur network setup, its always recommened to use a direct cable connection fore a more reliable and steady connection.
But I know myself that this is not always possible. Therefore, u can also choose the variant with the 2 power outlet adapters, if a direct wired connection is not possible.

Hi,
I forgot to ask. How much bandwidth does my antminer S19 need? I found online that it would need 5Mbps, however I did not find something specifically related to my Antminer S19, OK?
I want to figure out if I should pull a network cable from the router (2nd floor) to the antminer (basement), or should I use 2 power outlet adapters?
Thank you

Thank you very much philipma1957

If OP and others are going to be serious about their mining set on the scale of what @philipma1957 does then better follow their threads. I have been a secret follower of their threads and seen all the types of experiences that they have shared. Whether it is setting up a new miner, bringing in a new mining rack that can hold a big set up, or may be cooling down the entire mining farm, they have always seen putting their actual pictures and explaining what is happening at their facility.

I think that is the best way to go with it. You also share your experience and we can visualize the entire project with pictures. Please start checking out what they have done in the past. Moreover, there are detailed set up threads for dummies where one can get every bit of knowledge on how to proceed.

Hi,
I would have one other question.
The adapter you sent me the link of has 3 prongs, and my outlet has 4. Does it matter if I use all 4 prongs, or just 3?
For instance this one has 4 prongs:
https://www.amazon.ca/gp/product/B07P7YK39G?ref=ppx_pt2_dt_b_prod_image&th=1
Thank you

Either way should work.  let us know how it works out for you.

Thank you very much for your response philipma1957,
I already ordered the cables, and the outlet that you previously suggested, so I will see if I can find an electrician who would replace the existing outlet with the one you first suggested.
That adapter that you suggested  https://www.amazon.com/gp/product/B09WQVGNNR/ref=ox_sc_act_title_1? would be interesting because then I would not need any electrician to help me with the work.
I will think about those two solutions. I need only to send back the outlet and order the adapter.
Have a great day

Hi,
I actually quit the trafo solution as, from what I understood, it would get very hot, and become a fire hazard.
I got this information from several sources, so I opted in the end for the 220V line.
Have a great day

you can keep the receptacle you will just need the plug that fits it.

https://www.amazon.com/gp/product/B09WQVGNNR/ref=ox_sc_act_title_1?

works with some dryer receptacles


and it would work with


 this cable
https://www.amazon.com/gp/product/B0C4YWYGS2/ref=ox_sc_act_title_1?


and this cable
https://www.amazon.com/IEC-C20-C13-Splitter-Cord/dp/B07J6S348C/ref=sr_1_5?

so wall outlet =1)

adatper I just linked =2)

l6 -30p to c19 cable =3)

c20 to spliter c13 = 4)

Yeah, I would think that that outlet should be OK because as you said the electric dryer would draw a lot of power.
So you think that line should be OK?
Also, I would instead of the plug you suggested https://www.amazon.com/ELEGRP-Receptacle-Generator-Grounding-Industrial/dp/B08CXF9WDC/ref=asc_df_B08CXF9WDC? to use a plug fitting that outlet, right? The outlet is already there, so I was thinking that I should as well use it, no?
Thank you

CAT-5 or 6 will be fine as miners actually use very little bandwidth and are happy even with a 10mbit connection. It is not until you start connecting to several miners that connection speed between the router & miners becomes a concern.

most likely the plug will work as electric dryer 240volt lines draw a lot of power

Hi philipma1957,

Thank you very much for the useful information.
I checked again my situation in the basement, and found an outlet for 240V that was intended for an electric dryer, however because my actual dryer is on gas, this outlet remained unused.
The circuit is already on the electric panel and has a breaker, like for a dryer. Would this be enough?
Also I was thinking to use a plug for that outlet with a cable of about 6m that I will pull to a double outlet that I would mount on a wall. What do you think?
I think I will do this with an electrician to do all that cabling.
I have internet 1000Mbps in the house, so I would need a cat7 cable from the router (2nd floor) to the basement, to plug it into the Antminer, right?

Thank you again

If he uses a 5000 watt 120 to 240 boost transformer such as this one


https://www.amazon.com/Yinleader-Voltage-Converter-Transformer-VTUS-5000/dp/B09LQXP8R2/ref=sxin_16_pa_sp_search_thematic_sspa?

it will not work well

try and find a 50amp single pole circuit breaker.

and it needs more than  10 gauge wire it needs 8 gauge and there would be a proper plug to carry that much current.

Hey,

i am doing a similar setup as yours. Were you successful with the transformer?

You could, but I would advice against it, there would some energy loss in this process, better to install 220v.


It's called C13, ya it's the same plug as the one you use on your PC, but sure thing is, it isn't the same rating, you are going to need each wire to be at least 1.5mm square thick.


Nothing, just your Chrome browser or whatever you already use.


No, you use your laptop / PC, write the miner IP address on the browser, and you will be inside the miner to do the pool configuration.
 

You mean PDU? you can, or you can just get the Y split cable that phill posted above, the only issue with that Y spilt is that your breaker/socket need to handle the entire amp draw whereby using 2 single cables the load is divided.


Nothing has changed ever since, all you need is pool URL and a worker name.


Your mining payouts will be sent to whatever address to enter in the pool website, they don't know/care what address is that, which wallet to use is off-topic and should be taken to Wallets sections

I assume you have a usa based home due to 120 volt power.

Transformers are hard on the wiring.

if you bump a 1 line 120volt  wire to 240 via a transformer then pull 5000 watts you will very likely melt it.

consult an electrician ask for a 220-240 volt line with a L6-30r receptacle

https://www.amazon.com/ELEGRP-Receptacle-Generator-Grounding-Industrial/dp/B08CXF9WDC/ref=asc_df_B08CXF9WDC?

it will need 10ga  wire and a 30 amp 2 pole circuit breaker.


like this https://www.amazon.com/Square-HomeLine-2-Pole-Circuit-Breaker/dp/B002YEJITO/ref=sr_1_4?


buy this cable
https://www.amazon.com/gp/product/B0C4YWYGS2/ref=ox_sc_act_title_1?


and this cable

https://www.amazon.com/IEC-C20-C13-Splitter-Cord/dp/B07J6S348C/ref=sr_1_5?


so

1) 30 amp 2 pole in your circuit box
2) l6-30r receptacle on the wall wire with 10 gauge wire
3) l6-30p to c19 10 gauge 10 foot cable
4) c20 to c13 that I listed.

Should be safe up to 4000 watts or easy peasy 1 s19

lastly do you have hard wired internet with eth cables?

Hi,
I am new to mining, and am about to get towards the end of the month a new Antminer S19 95TH, so, as I have some time to prepare/plan, I was wondering if I could get some advice on how to set it up:
- I was told that I need a separate line of 220V, however I was thinking to get a step-up trafo from 110 to 220V having 5000W. Is this OK?
- I understood that the antminer comes w/o any power cables, so I have to get 2 power cables (similar like those for PCs) from what I could see on its picture, correct?
- what software do I need in order to have it mine properly?
- in order to configure it, is it possible to connect it to a monitor and a keyboard?
- I saw on a tutorial video that the miner needs 2 cables, so would I also need a UPS to plug those cables?
- as sometimes most of tutorial videos are pretty old regarding pools, and software used, is it possible to get a link towards a more recent video?
- do I need a cold wallet? I have right now 2 wallets on Crypto and Shakepay, however I understood that more securely would be a cold wallet, so which one would be a good one to use?
I am going to consult also this forum and see what I can find as information.
Thank you
