I agree.
I'm going to go with 1000w. Thanks for pointing that out!
The TDP of a GTX 580 is about 245w, more if it's overclocked.
With a 1KW P/S you've only got about 250w left for the CPU, motherboard, HD, etc.
You really need a 1250-1350w P/S at a minimum for 3 of them and a 1500w is probably a better bet.
