Seasonic 660XP2 Crossfire?

post #1 of 4
Thread Starter 
I am thinking about getting another hd 7950 for crossfire, I read that its recommended to have at least a 750w PSU. Is this really necessary, or will the 660xp be enough?

Depens on if you want to overclock your CPU and the cards or not

Well I have a 4770k at 4.4 and would want to run the 7950's at 1100/1500.

Then no you would be left with 125 watts or less on the PSU
