That reminds me, what PSU did you use Dogie? I'm looking at either getting one like yours or doubling up on a Corsair 850 modular psu (it weighs as much as a barge, I love it.).
Mine is on a DPS-2000 but that's more to do with the PSU already being on the right shelf than anything. 2x Corsair CX750Ms is the cheapest but requires 2 additional 2xmolex to PCI-E adapters. There isn't really a sensible single consumer PSU option, so 2x of whatever you can get should be okay.
Can a single 110V 15A outlet handle this? Thanks for your help!
110 * 15 * 0.8 = sort of but not really. I don't think officially you should be doing that 24/7 but its your decision.
