750 watts enough for 7970 crossfire? - Page 7

post #61 of 64
I also have two 7970 that are asus top editions ones however its not running on a tx750 but however its running on an AX1200. I one of those people when they have enough money, spends it all on newer components that may only be 10% faster. sometimes these components draw more power and as it adds on, it exceeds what the power supply can deliver. this year I went through 4 brand new power supplies and got an AX1200 so I never have the thought of "if I were to buy this, would I have enough power?" unless I was doing something like 4 titans, then that might be a different story biggrin.gif

I'm running two Asus HD7950 DC2 TOP V2 cards in CrossFire and 2500K @ 4.5GHz on SeaSonic G550W unit, no problem at all, even with cards overclocked @ 1000/1575MHz (stock voltage) system works fine.
