Topic: Antminer S1 power supply (Read 11783 times)

I powered two 400MHz S1 with one for six months without issue (except for one overheat in July when the PSU fan was turned too low).

Can the dell 750W psu run two antminer s1s well?

Here's my take on this.
After burning up one of my "decent" power supplies and stressing my "good" power supply, I looked for alternatives.
A regular PC power supply is also working to generate 5VDC and 3.3VDC.  We don't need these for an S1 with a pair of blades installed.
Since the Antminer S1 is only 12VDC input, I looked for a stable 12VDC power supply.
I picked up two Supernight LED Driver, 12VDC 30A power supplies, dialled them in to as close to 12VDC as possible (they are adjustable, one is at 12.00, the other is 12.02).
These have run cool and stable and I have my S1 OC to 393.75.
This is just on the bench, with a secondary 120mm fan drawing air out, and I'm peaking at 46* for temps.
The plan is to put a proper housing on them for cooling.
I've also put heat sinks on all of the ASIC chips and started putting them on the others but ran out (ordered more 6mm and 14mm heat sinks for the regulators and remaining small chips).
Heat sinks are like $25 per 100 count, so not so bad.  I've used them on my U1s as well.  I'll be resistor modding those soon and mounting them to a dedicated heat sink with cooling fan.
For less than $30 each on eBay, this may be an option for some of us.
The pair cost me a little under $56.

I used  PSU a server PSU, it works very stable!
In fact, almost any PSU can make the ants work stable.

Im running mine with 550W PSU and its running fine.

just blew my corsair 500 =\ I thought I was passed this. But Im also running 1 blade and 2 gridseeds with it... that was probably my downfall. upgrading to a 750

I plugged each PSU to an ant with double PCIE cables (which you use for your graphics cards).
Then I had an adapter that went from 2x molex to 1x 6pin and use one on each PSU.
In total of 1100W, each PSU is pulling 550-600W.

Hi,

I'm curious how you did this setup?  I want to do something similar.  I know you have to apply primary power to the control board side of each of the ants.

Just to update, I tried the 2 pci e connections on the strand, and noticed the wires started to heat up quite quickly. So I didn't leave them in for too long. So what I've done is put 1  6 pin pci e in 1 blade, and for the other I've took the 12v from the 8/4 CPU plug using a 6 pin female pci e connector and then spliced the ends to fit the 2nd blade terminals at ground and +.  I was getting 11.97vdc at both blades. Does this sound ok? I'm using a corsair 500 m

It's up and running ok. Looki gs good getting 180 gh+. Does anyone know what reject rates we should be getting at the pools?

Just a note if anyone tries this. Be careful not to get reverse polarity as the wire colors reverse when u connect them due to the pin outs.

I think the 62A should suffice for 2 ants. No OC'ing of course.Yuo'll be running at about 92-94% of max.

I purchased one of the server PSU's from minersource.net (was very professional and fast - would highly recommend them).  I think for long term, that is by far the best solution, assuming you can stomach the noise - which is the only drawback I see.  Highly reliable and high efficiency, and an excellent value - only around $80 to power two PSUs is great.

I'm running into a problem though, in that I might be in a situation where I need to run 2 S1's short-term and need another PSU.  Its a long story involving an eBay buyer who has to wait to pay me etc..

I have a Corsair AX750, which is a gold PSU that I use to run my desktop - that I was considering trying to use to power the two S1's for a week or two - depending on how long this eBayer takes.  It has 62A on the 12V single rail, and enough PCI-X connectors.  It has also been supply two 7950's running overclocked, along with an overclocked i7 920 - faithfully and reliably.  Link to the stats:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139016

If I was going to be running these two until they aren't profitable to run anymore, I would defientely buy another server PSU.  I'm not really excited though about purchasing such a dedicated PSU - I suspect it might be difficult to resell on eBay after everyone is using the new 1Th units that come with a power supply.

What is everyone's thoughts on trying to use that unit for a few weeks?  It still is covered with several years of warranty, but don't wanna blow up a unit because of something silly.

Thoughts?

Simple math.  is 17 (the current on the 12v rail that feeds the pcie plugs) > 28 (the current needed by the antminer)?

I bought a 525W cooler master power supply... it couldn't handle it and I needed to buy another to power the unit.

Make sure the 12 volt rail is rated for 500w +.

Hi, has this power supply ARTIC Fusion 550-EU  http://www.arctic.ac/eu_en/fusion-550rf-eu.html enough Ampere to power a Antminer S1?
It has +12V1 17A; +12V2 17A; Combined Output 408W
I have also an industrial power supply 12v 50A  http://www.andromedastore.it/home/art1/0/34727/26479/Alimentatore-switching-12v-50A.html can I use this instead a PC power Supply?

Thanks W_M

I have 2 RM750's powering 3 overclocked S1's.

Total wattage +-1100W from the wall and 4.8A

Take a look at this Dabs offer 64 quid EVGA 650W SuperNOVA NEX650G 80+ gold rated fully Modular Power supply rated, we get stung with the leccy in UK and this would save you 20% on running costs over cheap ebay effort and if you register online with Evga free 10year warranty.

hi

just got my antminer s1 and corsair 500m up and running.  the 500m comes with the 2 pci e plugs on 1 cable, i saw this mentioned before that its not a good idea to run the 2 off 1 cable so im just running 1 blade untill i find a solution. which im hoping someone can help me with pls?

it has another 2 port that are 6 pin on the psu, are these pci-e ports? what can i do to supply the other blade? what happens if i run 2 blades from the 1 cable? im not to savvy when it comes to psus etc...

thanks for any help guys

I bought the Antec 850 80+ Bronze and other then the motherboard wire there's a CPU wire, does it need to be connected somewhere? Or does it need to be jumped as well?

See the antminer setup guide and help thread here.

Thank you for posting the question davida (glad to see fellow miners from "across the pond").
The mention of running  2 AntMiner S1s on a Corsair RM850 almost makes me want to upgrade, even before getting the 1st Ant in hand (terribly addicting this mining thing;-).
I keep seeing people post about "bobby pins" and "paperclips" dandirk so you're the deciding vote, if I'm in a pinch I won't feel so squeamish about it.
There isn't a reasonable computer store within hours of my location, if I could get the setup right on the first try and keep it running...that would be great.

Wishing y'all much luck too :-)

I suggest one 800W bronze plus per OC ant...gets the best efficiency.  Efficiency will be important when connecting more than one ant to the same breaker.

This configuration should allow you to safely connect 3 ants to one 15A breaker.

It really is that simple...  Paper clip from green to black cable next to the green one.  You can also just google "power on psu without motherboard".

I would suggest you use decent sized "wire" and just cover with electrical tape to ensure safety.  Copper ground wire might actually be too big depending on the AWG, but try it.  I would say it should have some resistance to put in and take out but doesn't make your face red while doing it:)

I couldn't find a paper clip so I found one of those small black paper binder clips, took off one of the "levers" and bent the ends straight... it was some work but they fit and won't be going anywhere lol...

CX600 is fine, it's got 40A on 12V rail. More than enough.

I was thinking this...Corsair CX Series 600 Watt ATX/EPS Modular 80 PLUS Bronze ATX12V/EPS12V 552 Power Supply CX600M

http://www.amazon.com/Corsair-Series-Modular-Bronze-CX600M/dp/B00ALYOPSS/ref=sr_1_fkmr0_2?ie=UTF8&qid=1394295808&sr=8-2-fkmr0&keywords=Corsair+CX+Series+600+Watt+ATX%2FEPS+Modular+80+PLUS+Bronze+ATX12V%2FEPS12V+552+Power+Supply+CX600MCorsair+CX+Series+600+Watt+ATX%2FEPS+Modular+80+PLUS+Bronze+ATX12V%2FEPS12V+552+Power+Supply+CX600M

Is this sufficient for one Antminer S1 ?
will I need anything else beside the jumper (can I strip a copper ground wire and leave some shielding on, or is there a better way?)
Any other advice?

Thank you :-)

I have 2 antminer S1 on a Corsair RM850, drawing 730Watt from socket (on 220VAC, 50Hz).
The RM850 can give 70A on 12V rail, so there is enough to spare (because 730 / 12 = 61A not taking into account the PSU losses).
So my conclusion is that a single S1 miner draws about 30A in 12V. A PSU giving 35A should be ideal (to hit max. efficiency).

At the moment I'm using only 2 PCIe cables with dual connectors to power the miners. Cables are cold/lukewarm.
But since the PSU has 5 connectors for 8PIN or 6+2Pci-e I will change this to 4 seperate cables (for some reason only 3 PCi-e cables are delivered with the PSU).

I wouldn't go with the lower rosewill's had a bunch sent to us for hosted machines most of them died in less than a week

With the Rosewill 450W with free shipping, is 37A at 12v enough to power?

At $60 each, wouldn't be a bad deal - think it would push the PSU too much?

Thanks im in uk though and we dont seem to get these same brands as you in usa or the low prices   

cheers

That is a reasonable choice

3 x http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027 is 150 usd and is 85% efficient at half load ( http://www.plugloadsolutions.com/psu_reports/CORSAIR_CMPSU-500CXV2_ECOS%202415_500W_Report.pdf ) and you can turn them on and off individually and move to different circuits as needed.

1 x http://www.newegg.com/Product/Product.aspx?Item=N82E16817182063 as posted in a different thread of the same title costs 250 and is a brand I don't really know.  But, it will be around 90% efficient at the loads you anticipate ( http://www.plugloadsolutions.com/psu_reports/ROSEWILL%20INC._LIGHTING-1300_ECOS%202330.1_1300W_Report.pdf ).  Will that 5% efficiency pay back the extra hundred dollars?

Now, if you are willing to spend 75 dollars per unit, http://www.newegg.com/Product/Product.aspx?Item=N82E16817151136 for a seasonic or http://www.newegg.com/Product/Product.aspx?Item=N82E16817182068 for a rosewell get you the same 90% efficiency at a total cost of 225 USD.

Half the fun of this hobby is figuring stuff out.

Ive figured its prob cheaper and easier to go for 3 seperate power  supplies something like corsair 500w and then just have one per miner

I'd be curious about a (2) S1 PSU solution, along with a (3) PSU solution.  I saw the 1300 Evga recommendation, but I'm curious about the price vs efficiency - if it is worth it.  The price on amazon is $200, which seems like a lot - maybe I'm mistaken

Saying to someone figure it out yourself - kinda defeats the purpose of a forum.  Searching provides some answers, but hey, the question is already asked, so let's discuss

Blah blah blah 

Please do the math your self, more than enough info has been provide in this thread alone. Their are tons like it. Search, mining is not for Grandma and Billy Bob.

Anyone running two or three oc ant of one psu?  If so which ones?

Also do ants need modular or non modular type which is best?

thanks

Evga 1300 works great


http://www.scan.co.uk/products/1300w-evga-supernova-g2-80plus-gold-90plus-eff-full-modular-power-supply

also tier 1 of course

A single rail 500w PSU is more than enough. But when it comes to PSU's I'd purchase reliability over price any day of the week.

Here's a PSU tier list: http://www.eggxpert.com/forums/thread/323050.aspx

buy xfx 550 pro bronze
seasonic build
cheap
reliable
efficient
12v one rail
good looking

really good psu, it handles oc ant 205gh/s and 13gh old am blade without problem

i have been using plentyof them, mire than 10 and none died yet.

Has anyone mdone the thing where you run three ants of one psu?  If so which psu does it require?

thanks

I'm running multiple Corsair CX600M's.... sucks because I had to cut the 8-pin cpu cable and use the screw terminals on one blade each. The power supply has 2 pci-e connectors on one split line, a big no no. All mine are overclocked and running flawlessly. Max draw at the wall for me is 438 watts. YMMV

ant miners are 2 machines not one.

 your answer is yes just turn the psu on that sends power to the board with the ethernet cable..

you can wait as long as you want to turn the power on to the board that does not have the ethernet cable.

   to the op unless you have free power or very cheap power get a decent psu.   I run 2 units off this machine


http://www.ebay.co.uk/sch/i.html?_odkw=fractal+design+newton+1000+watt&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.Xfractal+design+newton++r3+1000&_nkw=fractal+design+newton++r3+1000&_sacat=0

power used is 720 watts   low end gear you will use 820 watts for 2.

 100 watts an hour 24/7/365 adds up to 876 k watts a year for 2 machines I realize this one runs 2 ants but you get the general idea.  what does a k-watt cost you?

Yes you can but to turn them on you need to power both PSU's at the same time (or close to it)


You don't have to order from the USA I was just giving examples, a Corsair CX600 should be able to be purchased in the UK.

No that will be terrible, none of the no-name brands are good enough to power a miner.

Try this: http://www.ebuyer.com/514902-cooler-master-b-series-600w-86-efficiency-12v-single-rail-psu-rs600-acabd3-u1

I couldn't say for sure with the ant but I have a cube running like this right now.  It's two 600w supplies that are an off brand and by themselves will not power the cube but using one cable from each works perfectly.

Here's an advanced level question:

I have two power supplies, 1000w and 1200w. Neither of them are great brands. The 1200w is running 2x Antminer right now. The 1000w has 3x PCIe 6pin. I would need 4x for 2 Antminers.

Can I run 1 PCIe from the 1200w and 1 from the 1000w to the same machine?

The 12V rail specs are not shown(biggest determining factor). You need at least 450 Watts on the 12V rail. 500W is all the rails combined. While it may work, it is inadvisable to use such a small watt rated PSU. Also, buying some no named brand is not wise as the PSU will see much high loads than would be typical in a PC. Would you buy a new car and put oil named ACME that cost $0.50? I sure as hell wouldn't.

I would look for a popular name brand with at least 550W, 600W should really be the lowest. Plenty of people have had issue at normal clock rates with sub 600W PSU. Also, a PSU with a single 12V rail is best.

The whole theory on replacing a cheap PSU if it breaks is flawed. Whats cheaper, spending $80 once or $20 four times?  Not to mention, you buy some junk PSU, you'll be lucky if it blows and doesn't fry the miner along with it. Another thing, all the potential downtime if the miner isn't fried, while waiting for a new PSU to come to ...oh wait only find out it's fired!  How about the odds of a junk ebay PSU arriving DOA?  In case I'm still not making sense, a quality PSU will more than pay for it self.

To be honest, I want next day delivery and certainly don't want to pay import taxes etc so I'm not going to order from USA.

So do you think that 500w psu won't give out enough power? or do u think it just isn't best to max out a power supply?

what about this 600w unit? would this be better for me?

I'd suggest going 600+ depending on brand you might get a day or two out of it if you go on the cheap side.

Here's a 750w that is capable of powering 2 S1's
https://minersource.net/products/dell-750w-psu-slash-adapter

The corsair CX600 will be good to power 1 S1
https://minersource.net/products/corsair-cx600-psu

We've used rosewill 750w they all blew up within a week or two, some thermaltake ones did as well.

Corsair's have treated us very well, and the dells have been treating us the best.

I have bought the antminer s1, just awaiting delivery now... I'd like it is someone can confirm to me or not will this power supply do the job....

it's 500w, the cheapest one on ebay.

If not, can somebody recommend a similar one, I don't really want to spend close to £100 on a name brand, I'd rather buy a cheap one that can be cheaply replaced if it breaks ( which i agree would be more likely with a cheap unit)
