what is the absolute minimun power supply i could get away with in this situation... what if the graphics cards were changed to gt's instead? no led's,no pci cards,nothing else

ocz 520w but that is a seriously power hungry pc.. pc power and cooling 510w is probly ur best bet. in the vicinity of $230-240 at www.frozencpu.com

Well if your running 2 6800 ultra's im taking it you will be running these with SLI then you will need a 400watt psu just on its own, so i would go no less than a 550watt psu to make sure them 6800 ultra's get the ample power they need to run with along with the other components you have installed.

i would go with either the pc power & cooling 510 SLI, the OCZ powerstream 600w, but i wouldnt get the thermaltake because..well they dont make the best psus.

dont go for minimum with a system like this, because you need good power to have a good system

I use an Antec 550. Solid rails, No problems. Ive also heard a lot of good things about the OCZ.

crash, while its a good psu, he needs SLI capable....
