The PSU seems to shut down when feeding it with just 2. It might be because the cables are made for just 75W and it pulls 180W through each (so it drains 360W in total).
So, I'm thinking can I plug a 3rd pci-e cable, without overclocking it just to spread the power a bit more, or it doesn't work like this?

the power usage is separate per side so the 3rd cable would just help distribute the power load on that one side. i'm not affiliated with minersource (http://minersource.net/products/dell-750w-psu-slash-adapter) or gekkoscience (http://www.gekkoscience.com/products/D750_supply_breakout_board.html) at all but i've purchased several of these products and they are prob the best use of your $ if you are going to run S1's, S3's, BTC Gardens, etc.

yes looks like much cheaper solution. My question is why everyone is using ATX PSUs then?

well i hesitate to call them morons or ignorant, but probably the latter. they either dont realize these products are out there or feel they are not as safe. or possibly the fact that they are pretty much targeted for this purpose only makes them harder to resell or reuse in a gaming rig later. gekkoscience's latest product can run 5x S3's - http://minersource.net/products/delta-dps2000w-with-adapter-board - with even some room for overclocking. you just have to make sure you keep it cool and have 220/240v power.

How do you keep it cool? And does it require some soldering?

i just have a box fan that i use to move air across it and push the stagnant heat to the other side of the room and it seems to keep cool enough.

no soldering needed. the board that interfaces with the power supply plugs right in and has an on/off switch and the power is distributed through screw-down terminals. the cables they provide with the unit are the U-type clips that slide in and you screw down.

I have originally wondered about the server PSU possibility. I got a good deal on my rosewill lighning 1300 watt($139) and my Corsair's($49 for the 750 watt 80plus bronze) ($29 for 600 watt 80plus Bronze). The reason I didnt do the Server PSUs was I couldnt find the breakout board option for sale at the time and I couldnt find info on efficiency.

How is the efficiency of the Server PSUs as compared to the 80+ Bronze, Gold or Platinum ATX PSUs?

Also, is it any easier on electric and/or heat to run on 220/230 volts AC as opposed to 110/115?
