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

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.

[/quote] 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.

Anyone make any further progress on this subject with Overclocked Units (200GH/s)?
Find a reliable 1000W PSU with 4- 6pin PCI-E ports?

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 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.

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.

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 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.
The fan noise on the dell psu's are quite tolerable when you utilize the 50% fan speed pin.

If this is the one you had, it popped because it could provide just 16 or 18 Amps via its dual PCI-E connectors, while Antminer requires at least 30 Amps. When shopping for a PSU either select a tested and recommended one, or look for a PSU with a single rail 12V which provides at least 40 Amps, and preferably with separate PCI-E connectors, not dual ones.
