Which PSU???

[WWS]

I need a power supply that will be able to handle two XFX GTX7800's cards.
I am not sure which to buy. I was looking at the antec TP2-550, is this a good PSU?? What PSU do you all recommend for running an SLI system??

have a look here http://www.computerforum.com/showthread.php?t=26944, post numbers 8 and 9 in particular.
bear in mind that a 7800 gtx draws less power than a 6800ultra

All good, all within your budget. There are more, but I can't go and list 20-30 PSU's lol. I'd try and stick with a modular, but make sure it's a good one first. Older modular PSU's lack performance and really don't hold up well compared to the new modular PSU's coming out now.
