4 Antminer S1's on 1 PSU ?

[pjcltd]

As the title says
What the best PSU to run 4 Antminer's that are clocked at 375

Or

do i run 2 PSU's with 2 on Each !!!!!!

You should be able to safely run 2 Ants on a 1000W PSU, or 3 ants on a 1300W PSU.

I would not try to run 4 Ants on a single PSU. It's difficult and expensive to find a single PSU that can run over 1600W.

Each Ant requires 2 dedicated PCI-E cables to safely run.

I'm running 2 ants per AX860 PSU and 3 ants per EVGA G2 1300W PSU

LEPA has a 1600W PSU but no one tried that yet

however there are some stable >2kW server psu's

Apparently a 530W psu can run a standard (not over clocked) S1. So you'll need 2.12kW to run 4 (530*4). These are all my assumptions, but sushi told me that 530W should be able to run a 180gh/s S1.

The 500w measurement is completely false, was done w/ a shitty PSU. At the wall w/ a 80+ GOLD @ 120v, I see about 1w / mhz, so 400mhz is about 400w! Take 10% off that and these use roughly 360w @ 400mhz, on the PSU itself.

My bad then. Sorry for the false info. At least I learnt something new today

Agreed, all of my Ants use less than 400W at the wall running at 200GH/s using a good quality, Gold PSU.

i think you should use Corsair ax860(comes with 7 years warranty) platinum it has a 93% eff. on 230v i used to have 2 antminers @ 180ghash stock clock and 25 usb sticks with no problem. best psu you can get otherwise you should go for the Evga Supernova 1300 Gold(10 years warranty) where u can run 3 ants on.

Fortron Raider S 750W (80+ Silver) - two S1 non overclocked 735W at the wall (230V)
and if one unit only then 359W at the wall

Ok is any one using server psu's?


IE dell hp?

had one running on a DPS-600 but did not had my kill-a-watt then so no numbers
it's said these have far over 90% efficiency

Apparently a 530W psu can run a standard (not over clocked) S1. So you'll need 2.12kW to run 4 (530*4).

thats because all pc psu have a max load for 3.3 + 5V + Antivoltages and another max for the 12V rails wich is then combined to the official watts on the box. while high power "gamer" supplies tend to deliver up to 95% of their stated power on 12V

so you need a "reserve" on a 500w one but can run 3 ants on a 1200w one instead 1500

I will be getting a bunch of the Dell 2950 PSUs to use next week, I will report back.

I have a few coming in for a customer
Do you know the pin outs for them?
 I would like to try them before I send them on

I was running one unit off a Dell N750P PSU. The fan noise was a killer though, so today I switched to an IBM DPS-2500BB A PSU, cooled with two 3000rpm 120mm fans I strapped on the side of it. At over 200 ampere at 12v it is a total overkill for one antminer so I'll try hooking 3 more units to it tomorrow.

EDIT : if sidehack comes though with his mod thingy and I will be able to tune the fan speed on the Dell PSU, it'll be perfect, as I really like these units. Very compact.

with a killawatt check, my s1 uses 420@stock and 490@200ghs 400mhz. put 3 on a 1350watt psu, which claims 1500 watt peak, was running fine on one batch but on another on of the s1 switches on and off, i assumed it was not getting enough power, underclocked it was fine.

was told that running the psu at peak reduces its life by 40% and may even damage it.

whats side hack unto on the PSU's
do you have a link ?
