Re: Feeding the antminer S3 with 3 pci-e cables?

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.
