Topic: Antminer S1 power supply (Read 11673 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:

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 :-)
