sli and psu

[xNIKx]

how much watts does my psu need to support
dual 256mb 7900GT or 512mb 7950GT

a good 500watter should do

i ran 7800GT SLI with a Seasonic S12 500watter and it was steady as a rock. the 79xx's are built on a smaller fab process so should use the same if not less juice than the 7800's

i was thinking a 600W
