I have 3 overclocked running on a 1500W Silverstone using 4 PCIE power cables and 2 x dual molex to PCIE adapters (the ones you get with graphics cards). All cables are cool to touch.

Ye that psu is bad boy quality.

why only 4 pcie cables it offers upto 8, Is it to offload from the 12v rail?

I use this PSU for all my Ants now
we have 12 Ants on 3 PSU's
all oC at 375 that give us 200Gh/s no heat issues at all

I run 2 S1's on a Corsair RM850. They are both standard not oc'd and the cables are cool to the touch. The fans on the PSU's don't even come on.

most comfortable option is at least 750 for 1, 1200 for 2, overclocked. they dont use all that power but its more the cable size, they tend too get warm with the lesser psu. the 1500 watts have good thick cables you dont feel anything.

i measures 490 watts overclocked at the wall per unit.

i have 2 ants oc-running on a 1kW bequiet powerzone 1000 with cool cables and 810W at wall

are they overclocked also?

Anyone make any further progress on this subject with Overclocked Units (200GH/s)?

Find a reliable 1000W PSU with 4- 6pin PCI-E ports?

i just had a powercool 750watt psu go pop after a day on 1 s1, exchanged it and the second went after 30 mins!! whats am i doing wrong?

You might want a dummy plug for the ATX plug. I thinks someone mentioned this happening when the jumper wire shorted.

It sounds like the power supply is not high enough rated you might want to concider using gold rated or platinum. I have a 750w corsair and unit overclocked and shorting the 24pin with a strong enough wire and each ant is running perfectly fine so far.

If you are using a basics none branded or generic and not modeler power supply or anything under gold rated you will get problems. Also make sure your using 1 pci-e cable per 6pin connector and not using 1 with the splatter on it to connect to both modules. I use 1 for each module so total use is 2 pci-e cables connected up.

yep absolutely right. Cheap Psu it was fine in my bitburner fury es for a few month But they don't consume as much. I'm using silverstone strider 1500watt and some corsair 650watt.

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.

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

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.

Ok is any one using server psu's?

IE dell hp?

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

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
