hello
I buy 2x antminer s1 and would to connect to 1 PSU.
I found that PSU

http://www.ebay.co.uk/itm/NEW-STORM-SILENT-800W-POWER-SUPPLY-12V-DUAL-RAIL-32-AMP-SATA-MOLEX-120MM-FAN-/261384985436?pt=UK_Computing_PowerSupplies_EH&hash=item3cdbc25b5c

please told me , this is good or not? I can connect 2x antminer s1 to this PSU?

p.s. sorry for my english.

Don't bother, get a Corsair 850 or 1000 W PSU.  They're modular, single rail, usually 80% or higher efficient and just overall reliable.

That thing might blow up on you, especially if you try to overclock the Ants.

What you thing about this PSU? Will be ok?

NO!!!  Single Rail not double!!

CORSAIR, I repeat....CORSAIR ONLY to be safe.  You spent on Ants, you might as well spend on the power supply.    ;D

Ok:)
This will be ok? I connect 2 Antminer s1 to this PSU?

PERFECTO!   8) 

Good choice, buy it now!   ;D

Thermaltake has worked pretty good for me, too.  Even had one that died after a few hours (pretty sure it was a delayed DOA), but none of the hardware attached had any damage.  Just for the love of Satoshi don't use some random one off eBay.  You may save a few bucks, but you'll be crying when it blows up along with your miner.

really curious, why not double?

Corsair RM 850 is fine for 2 overclocked Ant's

You can potentially overload one rail if it's 2.  Power draw is balanced on a single rail.

I've been running 2 overclocked ants on a single Corsair RM 850 for a few days now.  2 oc's ants only draw about 400 watts each on a gold-rated psu.  I was unsure of overclocking 2 ants on a 850 watt psu before.

Better use 2 PSU...
If 1 PSU down for whatever reason, the other still up :)

I have 5 ants, 2 pairs on a RM850 and another on a RM750. I agree about the comment - if you lose one PSU you lose 2 ants, probably get a spare in at some point.

Many companies sell superior psus to corsair these days, I would take Seasonic, super flower leadex, xfx black (made by seasonic iirc), Fractal Design R3 any day over all but the AX corsair supplies (some of the ax ones are/were made by seasonic ;P)

I didn't want to start a new topic since I had a question so related:

I have this power supply, it is brand new. http://www.amazon.com/gp/product/B007WLRJCC/

Will it be fine for powering 2 Antminer S1's without any problems? Its a single rail and 1000w. Its not the most efficient rated PSU, but any other issues? Thanks for any advice!

Rail 1 +12V: 83.3 A

just that simple 60+ amps on 12v rail and you can do 2 overclocked s1's

Less than 60 per rail -- good luck with that....

for 2 overclocked   these die

BTW the enermax is 4 rails amp each  but it is very clearly marked  so it is okay to use.  bitmain uses it in their new s-2's


multiple rail is fine if you understand how to hook it up.


I was really annoyed at the fractal psu's I got them for 200 each the are dead dead dead.  and the seller is fucking around with my return.

And make sure the P/S has 4 PCIE cables off that rail, 1 cable to each ant... Not one cable with jumper splice end.

What about 3 ants on http://products.ncix.com/detail/xfx-1250w-pro1250w-black-edition-70-65627.htm

single rail 1250W XFX PSU

Yes, 100a single rail, you only need 90+a so it is below maxed out and may last awhile if you keep it cool.
8pcie leads is good, that is what we use for quad sli for game dev, however I demand Corsair...

XFX would not honor a warranty on a MB that was only a month out of date.
EVGA MSI GigaByte ASrock all have had no issues with me usually sending a newer board if the old one I have is no longer available.
I will never forget that, and refuse to own XFX because of it. XFX support was impersonal, and could give a damn atti-dude.

Blew up on me...with 2 OC Ants...in 2 days...piece of sh.t... :)

+1 this! Make sure the PCIE connections run off separate cables. Some PSU's will state 4 x PCIE but it will be 2 cables with a splitter on each end such as the Corsair RM850 (which states 6 x PCIE but really its only got 3 cables)

I've been using 2 of these to run 4 Ants for the past month and so far so good... can't complain for £120....

Why is single rail preferred? Can anyone explain in detail? Most 500-650W PSU's are dual rail.

Two rails mean that each one only can provide half of the PSU's total power.  Good chance you'll overload it just putting a normal size load on it from miners, as all the PCI-e connectors would only have half of the total wattage to use.

It is quite cheaper to build multi rail jobbers, as the transformer and voltage regulation can use much less Robust (less expensive) parts.
Just in weight a good P/S will have about 5lbs of copper in it.

I had a coolmax Zu-900B.  I had two NON-OC Ants on it and it blew.  Coolmax does suck.  RMA in process now.  Was bought in Feb.

It did not damage the Ants.

Coolmax Zeus 900...or 1000W...Cheap Chinese piece of crap...DON"T buy them...

i find is great. Corsair RM Series 850 Watt

I use DPS-800GBA server supplies from HP they are cheaper and high quality they run two Ants over clocked no problem at least as good as a Corsair and half the price.
