APW5, 1300W-2600W PSU
Power chord is not included with the APW5. It requires a C13 chord with a minimum current of 16A. We advise all users to purchase it separately according to their local wall-socket standard

Does this mean that i cant run 1 machine on a 110v 15amps or 2 machines on a 220v 30amps circuits because the power chord requires 16A minimum??



no.  


lets go slow  and explain  

 1300 watts / 110 volts = 11.81 amps

 2600 watts / 220 volts = 11.81 amps

so a 15 amp cord  x .8 = 12 amps     the 0.8  is  80 percent de rating factor due to your 24/7/365 day use.

so 15 amp cords should be good enough.

give me time to link a good 110-120 volt cord

Despite the ROI probability of this machine it is still appealing to home hobby miners like myself who do not mine for ROI, but rather for the enjoyment of tinkering.  I'll wait for the used market to develop before I pick one up, or a 3rd party group by, because I told myself I'd never give bitmain my money directly.  But I am attracted to the noise/heat output of this little box.  Of course Avalon has something on the horizon, so I just may end up with one of those instead...

That's exactly my situation. I mine for fun. My S7LN is just about earning the electricity it uses. This would actually put me in profit electricity wise but would never make enough to cover the cost of it. So would have to wait for a group buy or second hand one to appear.

Over a year R.O.I. No Thanks

Yeah, this only makes sense to those folks with 3-4c kwh usd equiv electric costs. They probably also are scratching their heads on this on say
a 9 month roi or so (guessing) from even their perspective. (chime in here you lucky buggers)

Thus ..another pretty 'trophy miner' ....never gonna find another 'asic wife' for the home I guess Sad

(not at frigging 14c kwh summer and 11c kwh winter that is....
my 'geography' for electric costs suck)



Unless you can really use the heat produce to warm a room you need to warm anyway with electric heaters. But it needs to have a manageable noise level... I strongly agree that the ROI are harder to reach nowadays.
I used to use my miners in the winter as well but such I live in a climate with variable weather so keeping them on consistently for heat wasn't needed.

I understand. It's clear that depending on the setup in the cold months it's really great to be able to use the heat... as long as the noise doesn't make unlivable. They are great for dehumidifying too, they heat the air which takes more humidity and then open the window when it's dry and cold outside and repeat.

It's the same thing over and over they probably have these mine until a sucker is ready to pay more than they know they will make, don't worry though they will sell. Looks like it is the same old it is better to just buy and hold story and buy sticks as hobby miners for fun.

I guess it is hard to keep the price down on there end....even though I think the price is high on these R4's at $1300 bucks....from looking at their past units..they always seem to sell out
quickly...guess it pays to be the only (sorta almost besides Avalon) mining game unit in town.......I understand it from my newbie days...I got a Jupiter in July 2013 that supposedly
would take a year or more to ROI......(it ROI'd in 3 weeks due to the BTC pump due to dumb luck) ...so heck newbies are overpaying for the first batch...but we have to
'infect' er I mean 'inspire' the new crop of kool aid drinkers to crypto I guess Smiley

300+ day RoI with $0.1 USD/KwH electricity... Cheesy Cheesy  with new price over one year.. mining is on dead..

Nope  but bitmaintech need make a simple adjustment .  Let us buy the r4 with paypal.

If I buy my r4 with paypal.  and use my discover card I get 1 year warranty added.

This means I have 90 day + 1 year warranty on the r4.

that is 15 months.  roi should be 10 months.

So  here is the deal bitmaintech  allow us to buy the r4 with our paypal account.
And if you do it right and are able, you can use PayPal credit and get 0% interest for like 6 months or something.  Zero interest is free money, so that might make purchasing these even more attractive to some buyers.

looks like max on warranty extension is 2x up to 1 year.   So   90 day would 2x to 180 day warranty , but as you say  if you have paypal credit you get 6 months with no interest.

And a 180 day warranty on it.  makes it bearable   or at least close to bearable. to get one.

I have a few questions...I'm considering getting the R4 and it would be my first home rig. Are all the cables included or what else is needed beside the PSU and R4 itself? Will any standard 110v jack really support it?

make a 110v line into 220v is my advice ...check out youtube it is easy to do with just a 220 plug at one end and the 220 double breaker at the other. It involves no wire pulls
you just tape the neutral with black tape at both ends and use it with the standard black for the 220 breaker....and ground...no neutral reguired.

Anyway youtube videos should clear up such a switch on how to make a new circuit (with 20 amp 12-2 wire) and or mod an old one to 220v.

Others on here can offer other advice on specific miner setup or further links to my stuff above

reason for 220v is more efficient



Thank you so much for taking the time to respond to my post. It really clarified everything and I'm having an electrician over in the morning! I will see if it's possible to do that conversion - Do you really think it's worth it in efficiency for simply 1 miner? If I am unable to make the upgrade from 110v to 220v, how should I proceed (is it ok to run it in your opinion?). I am certainly going to look into a whole house surge protector as well. I was initially going to do grounding on just the outlets upstairs, but I assume that wouldn't even be necessary with a whole-house one? But would 3-to-2 prong adapters really be OK to use with all of this mining equipment?

If your goal is to have one miner, and one miner only, never expand, keyword NEVER. Then yeah a 110v line is ok so long as the cable behind the wall is thick enough to handle a constant 900-1000 watt draw 24/7. Also, keep in mind that whatever circuit you use for the miner probably should not be shared with anything else to avoid tripping it. Last thing you need is for you or someone to plug a vacuum into the shared circuit and blow a breaker.

If you think that you may want to add another miner later on, go for it, wire up the 220v plug. Just keep in mind, unless you're doing the work yourself, an electrician is gonna charge you a pretty penny to fish electrical cables through walls. Back before i expanded the home mini-farm i was using one of these https://www.amazon.com/gp/product/B000U3BVNC/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1 duplex 240v outlets. More than sufficient for two miners given you've got the right cabling behind it (i used 10 AWG).

My question to you is this, if you're going to go through the trouble of wiring up a 220v plug, why not go with an S9?

But would 3-to-2 prong adapters really be OK to use with all of this mining equipment?

I'd ask the electrician but truthfully I'd go 220v on one outlet..even if it took snaking one in...I'd not use adapters on this 1 line conversion or addition

i use the below surge protectors they have saved my butt 3x in brown out issues that have only mucked up the SD cards

https://www.amazon.com/Tripp-Lite-International-Protector-EURO-4/dp/B00006HZ4M/ref=sr_1_1?ie=UTF8&qid=1472536001&sr=8-1&keywords=tripp+lite+euro

you need to get a plug from the wall to the unit (from the unit to the psu for miner the cord is included) I use this type of 220v cord

https://www.amazon.com/gp/product/B0093WFT6G/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

use the proper wall plug on the outlet you can get from home depot.

But with 100 amp service and heat issues 220v is less of a strain on the equipment or so I understand it

Not quite sure why a centrifugal fan has all its sides vented if its in push configuration as they usually intake from the ends and spray air radially. You control the direction of flow with a cover or case which they're not using. So if its in pull configuration then how is it generating enough pressure as a centrifugal fan surrounded by open vents?

 2 sides, not all - but that's STILL an odd design decision that one would think would reduce the fan efficiency.

 There is NO reason the R4 can't be run on a 110 circuit - it's actually a TON better for that than the existing S9 units that force you to push a common 15 Amp 110 circuit VERY hard. 8 amps or so draw is VERY easy on a 15 amp circuit, and 2 would be practical (using seperate OUTLETS unless the outlet itself is one of the less-common NEMA 5-20 type) on a single 20 amp circuit.


 One of the pages linked somewhere cited "515mm" width - that's a bit over 20" and will NOT fit in a standard rackmount space.
 It's a good fit for my homebuilt "made to fit A2 Terminator" wood shelving though - almost identical width, and a bit lower in height.

Can you share a link to the youtube video? I found a bunch but they didn't seem to show details...

https://www.youtube.com/watch?v=XMgwZDtR4tw

hopefully this is on topic on how to convert for an R4 for use with a NEW 220v outlet above

IF you just want to convert a 110v outlet..make sure you have 2 spaces (you take out the single 110v breaker and make sure you have one more space in panel) you then put
in a 220v double pole breaker (ask home depot guy bring old 110v single slot breaker to get the right model) and put your preferred type of 220v plug (you can also ask home
depot guy his preference) find a proper psu cord for that wall outlet to your switching PSU (the new ones switch from 110 to 220 auto mode sense I assume this bitmain one
does as well) ...and again you simply put black tape on the neutral both ends (making it black a power lead of 110v) and use the current black (other 110v) and the ground
at both ends and the outlet...

and you should be good....any other questions PM me...we will wrap it up off this thread I assume we are still on topic due to others may also want 220v instead of 110v
for these units and the above is an easy fix.

You also have to make sure that the ONLY thing on this line you are gonna convert ONLY has the ONE outlet on  it....or ALL the outlets on  this circuit (lights won't work for this) will
have to be 220v outlet change..this is for a conversion of an existing 110v line to 220v outlet.

again running a single line  NEW from panel to the outlet is specific to the link above and is what I would recommend even if you have to fish some wire around the house.

anyway ....if you are gonna run this R4 beast imho 220v is the ONLY way to go....no way do you want it to run on 110v even if it works ..others can get into the detail
on why that is so on here or to you via pm. Also having an electrician do it is probably the wise choice on either a new line or a conversion....BTC is gonna go to 1000 usd
after you get your R4 right Smiley So you can afford it! Smiley After you have this done or do it probably not a bad idea to have it and the house inspected and signed off on all this
electrical stuff anyway....they also have whole house surge protectors ..(which I should probably do) ...anyway whatever way you go you want these R4's at 220v imho.



Thank you for the explanation. I actually wanted to add in that 2 pole breaker a while back but then I realized I had too many other appliances would not work at 220v. I live in a small condo so choices are very limited. If I move into a big house then I would definitely devote the entire basement to build my own farm lol.

And  gpu mining looks better mostly due to sales and warranty tactics of btc ASIC builders.

the problem is that each manufacturer makes their own mining chip. if there was something like Intel/AMD duopoly and anyone could order from some company (ies) like this, then final product (miners) would have quickly commoditized resulting in lower prices eventually. the problem is that this market is too small (so far) for a serious player.

new fan design seems to be more efficient & quiter, kudos to that but here are my thoughts on the R4

1. there ain't gonna be any easy find for the FAN if it breaks down = DOWNTIME !
2. the heatsinks are in a 90 degree orientation so you can only run R4 blades
3. this thing looks WIDE, hence taking up rack space & NON stack-able but imo with a little creativity & simple mod/add on should solve that problem
4. still the same 3 x PCIE jacks for each blade but the orientation does NOT allow for wiring management say if you purchase 2 x R4 with the new PSU but on the new PSU i think I see ONLY 7 PCIE & not 14 of them, well I could be wrong though & it will be most likely to be 18 AWG sizes.

let's see when it launches & my guess was REALLY close with BMT pricing it around 1.7 btc ish range, the PSU is nice for newbies but for the hardcore diy'ers out there, there are alot more options & much cheaper PSU with the same power or more.

will the S9 prices drop after the R4 launch, i'd say NO !

atm, it's difficult for me to purchase the R4 atm UNLESS there are readily available parts with reasonable pricing or any other aftermarkets. The ONLY PROS on the R4 would be most likely cooler chips & quieter miner but i'd still go for the 11.85 ths S9 as i think the EOL will last longer than the R4 & the pricing per ths should be more or less the same & the S9 have some available aftermarket parts readily available.

just my 2 cents.


All solid points, but let's see price and WARRANTY. A consumer item should have warranty of 1 year minimum.
Prediction: they will price it too high, but will relatively quickly drop it once A7 shows up.
In fact, perhaps A7 is also consumer oriented and they are trying to preempt it. We shall see.

sadly :

NO way it's gonna be a 1 year warranty
YES the price will be HIGH & NO the price will NOT quickly drop
A7 price or Avalon prices are ALWAYS a tad more than BMT prices sadly

in other words be prepared for a ROI target of a minimum of 1 year or MORE

so sad but very true EXCLUDING downtimes, warranty claims & the other usual stuffs.

Then it is NOT a home item, period.
Mass consumers are not like us, who just turn another cheek and wait for it.

Can you share a link to the youtube video? I found a bunch but they didn't seem to show details...

https://www.youtube.com/watch?v=XMgwZDtR4tw

hopefully this is on topic on how to convert for an R4 for use with a NEW 220v outlet above

IF you just want to convert a 110v outlet..make sure you have 2 spaces (you take out the single 110v breaker and make sure you have one more space in panel) you then put
in a 220v double pole breaker (ask home depot guy bring old 110v single slot breaker to get the right model) and put your preferred type of 220v plug (you can also ask home
depot guy his preference) find a proper psu cord for that wall outlet to your switching PSU (the new ones switch from 110 to 220 auto mode sense I assume this bitmain one
does as well) ...and again you simply put black tape on the neutral both ends (making it black a power lead of 110v) and use the current black (other 110v) and the ground
at both ends and the outlet...

and you should be good....any other questions PM me...we will wrap it up off this thread I assume we are still on topic due to others may also want 220v instead of 110v
for these units and the above is an easy fix.

You also have to make sure that the ONLY thing on this line you are gonna convert ONLY has the ONE outlet on  it....or ALL the outlets on  this circuit (lights won't work for this) will
have to be 220v outlet change..this is for a conversion of an existing 110v line to 220v outlet.

again running a single line  NEW from panel to the outlet is specific to the link above and is what I would recommend even if you have to fish some wire around the house.

anyway ....if you are gonna run this R4 beast imho 220v is the ONLY way to go....no way do you want it to run on 110v even if it works ..others can get into the detail
on why that is so on here or to you via pm. Also having an electrician do it is probably the wise choice on either a new line or a conversion....BTC is gonna go to 1000 usd
after you get your R4 right Smiley So you can afford it! Smiley After you have this done or do it probably not a bad idea to have it and the house inspected and signed off on all this
electrical stuff anyway....they also have whole house surge protectors ..(which I should probably do) ...anyway whatever way you go you want these R4's at 220v imho.

I have a few questions...I'm considering getting the R4 and it would be my first home rig. Are all the cables included or what else is needed beside the PSU and R4 itself? Will any standard 110v jack really support it?

make a 110v line into 220v is my advice ...check out youtube it is easy to do with just a 220 plug at one end and the 220 double breaker at the other. It involves no wire pulls
you just tape the neutral with black tape at both ends and use it with the standard black for the 220 breaker....and ground...no neutral reguired.

Anyway youtube videos should clear up such a switch on how to make a new circuit (with 20 amp 12-2 wire) and or mod an old one to 220v.

Others on here can offer other advice on specific miner setup or further links to my stuff above

reason for 220v is more efficient

Actually not bad price for plug-and-play all the way from 110v up to 240v.
But 7 pairs of PCIe, making only 14 total?

 Probably designed specifically to power a pair of R4 units - 1 PCI-E per hashboard, 6 hashboards + controller seems likely.


 While the ORDER page links seem to have been dropped or changed (perhaps posted in error), the PRODUCT link to the "comming August 29" page IS still up and active. Looks pretty "official" to me.

Current price for the batch 12 s9 @ 12.9THs gives $123 per THs. PSU not included.
The R4 @ $1k and 8.6 THs is $116 per THs... PSU included.

Bitmain APW5 PSU (2600W 220V / 1300W 110V)

Whoah, that's one beefy PSU!
And the price is beefy too! 300USD

If true that is not to far off of current PSU from Bitmain assuming you mine 2 R4's off new PSU.   The APW3 is 120 right now so 240 to run 2 s7/s9 (with 2 items shipping could factor in  some to possibly higher.  If price is right 300 the new PSU is going to be higher price per miner.  But with silent and run's off 120 or 240 will be interesting to see how sales of them are.

But 7 pairs of PCIe, making only 14 total? Rather odd number no? I would have gone with 20 for the option of 2 s9/s7's (barely) @ 240v or 1 s9/couple undervolted s7's @ 110v in.

edit: I really should start using more of the IBM DPS2000 supplies (with your breakouts & cables) I have. Right now only have 1 in use. Just that getting the Bitmain ones got to be too convenient since if I needed one I ordered the same time as getting a miner.
Still use the one setup like I did for my old s5's - just set the PSU an inch or so away from the the intakes so the miners do the airflow required. No fans needed. Smiley

Sweet, a 2600W PSU with 14 jacks. I sure hope they're 18AWG so people use a buttload of splitters to run more than one miner and end up melting down the wire. For less than that $300 I could get you two 1500W PSUs with 12 16AWG cables each. I mean 2600W in a single PSU is pretty great but I still expect to be disappointed.

Given rated 845w total load and 6 boards giving 140w per-board my bet is 1 PCIe power jack per board.
wonder how well it would fit in an old s4 case?

Or the 4U high case from the miner A1 chip Dragon clone  (1.1THs @ 1,350w) that AMT finally sent me 8mo after ordering...

It is probably 2 boards with 3x PCIE power connectors each.
Took another look at the pic on Bitmains site and yer right - it shows only 2 cables running from the controller to the hash boards. So, 2 hashboards slid into the partitions guiding air and giving nice support.

If you are on about rack mounting it, it looks like its about 20 inches long so I would imagine the boards would be too long Sad

Could you mount the boards length ways in a old spondoolies case tho? but I would imagine you would have heat issues toward the back of the case imho.

Would be willing to give it a go if I had the spare cash
Well if the more common 19" racks are out, there is always the EIA 24" wide ones used in the AV industry...
edit: just looked, 610mm is 24.01568" so even EIA racks are out. But still, I see a lot of aftermarket case possibilities for this. Or branded casing from the retail chains. It *is* targeted at the home market after all so maybe just a couple per household. Ya know -- a mass-consumer Bling item Wink

Given rated 845w total load and 6 boards giving 140w per-board my bet is 1 PCIe power jack per board.
wonder how well it would fit in an old s4 case?
Or the 4U high case from the miner A1 chip Dragon clone, 1.1THs @ 1,300w) that AMT finally sent me 8mo after ordering...

If you are on about rack mounting it, it looks like its about 20 inches long so I would imagine the boards would be too long Sad

Could you mount the boards length ways in a old spondoolies case tho? but I would imagine you would have heat issues toward the back of the case imho.

Would be willing to give it a go if I had the spare cash

Sweet, hadn't seen that photo yet. I was just going off logic. Looks like the boards are laid out pretty much exactly how I figured they were.

The control board uses a 6-pin. I would bet the hashboards take 3x 6-pin each as well.

yeah this photo looks like you are right >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>V

That does look very interesting indeed, I wonder how wide it is and if it 19inch rack mounts easily?

EDIT: just looked, and its 20 inches long so no hope of a rack mount

miner software authorship aside -- I've been waiting to see something like this from Bitmain or others. Long over due. Give it a snazzy looking case to look like AV gear and they will have a winner.

Reason: I'd bet beans to btc that they are eying the large retail store market. More specifically the ones in Asia as a whole at least to start.
The main hypermarket stores to a Western eye are -- insanely huge. Think Walmarts, large furniture/bedroom store, massive consumer electronics sections, groceries and eat-there, you name it. The one I visited in Korea (I think was a Lotte Mart in Daegue) even had their own moped and car dealership inside. All in one 8-story building.

In late 2014 before he cut all communications, Joshua Zipkin now aka Joshua Alexander was talking about him drumming up extreme interest from a Korean chain for his last-ditch efforts to keep AMT alive. Well at least be able to finally dump the scads of A1 chips he had...

It should be in the Skype AMT room chats link in my sig, somewhere around maybe late July or so.

Are they still using a crappy hack job of cgminer?  I'm sure the answer is yes.  Until they actually support Kano and Ck, and cgminer proper, I will never give Bitmain a cent of my money.

Avalon A7?  Proper cgminer integration?  Yes please.

looks like the power to the boards is not pcie cable .  maybe a custom break board .  this may mean you must use their psu.

I would want some kind of filter on the incoming side tho, if its aimed at being used in the home environment.

Yea lokos like a new psu they are going to do alongside the R4.

Current one is APW3-12-1600-B2

New one: APW5

From the picture looks like its got a fan ontop rather than the server type fans the previous model had.

Interesting design cant' wait to see hat it does in real world.   I'm not so much interested in quiet of new fan design, but would love to see if it keeps it even cooler.  As it looks like a big area for fan.

One other thing is does it look like to anyone else a new PSU - https://enshop.bitmain.com/adv/detail-R4-gallery.html ?   I'm wondering if they are going to be selling new PSU's for this model.

Not quite sure why a centrifugal fan has all its sides vented if its in push configuration as they usually intake from the ends and spray air radially. You control the direction of flow with a cover or case which they're not using. So if its in pull configuration then how is it generating enough pressure as a centrifugal fan surrounded by open vents?

This is great news, but BITMAIN knows that to truly make an accessible miner, they need to price it reasonably.

Maybe something to fight the A7 ?

That's what I was thinking..


Price cartel is a much more likely scenario.

Indeed and Avalon never really fought Bitmain price with the A6

Bitmain Spondoolies fight was great for us, as it resulted in lower S5 and Sp20 prices. Let's hope for a similar situation, but with both companies being chinese, it is less likely to happen. Price cartel is a much more likely scenario.

It all depends on a price...whether it will be stupidly high or reasonable.
Reasonable price is $650-700 before shipping.
Price it like this and mass adoption at home could happen.

Now it is my theme such as advertising the new R4 product

https://bitcointalksearch.org/topic/bitmains-refused-from-s9-warranty-buy-at-your-own-risk-914354

S9 is really with a wrong design

Tupsu,

I do feel that you got the short end of that stick, if for no other reason aside form the fact that you've spent over 300 BTC with them, they should work with you on a replacement... So unfortunate...

I guess we'll have to wait and see what the pricing looks like, if its anything like S9 pricing my bet is between 1000-1100 USD. Hopefully they've got an improved warranty in the pipeline, I think that would do wonders to improving their image. Maybe this is a precursor to the next Avalon miner???

Here's guessing that pricing will put this at a ROI of ~350 days.

I don't mind bending over, but not for these micro-dicked Chinese vendors screwing over their customers with abhorrent business/warranty practices.
