i have a antec 1200w psu. looking to upgrade mobo to GA-990FXA-UD7 and install 2 6950s on top of the 2 i already have. will my psu be able to support this. recommendations please?
It should enough,the 6950 is power efficient @ 150-200 watts load x 4=~ 800 watts.Only question would be do you plan on overclocking as those recommendations can certainly increase due to overclocked power requirements.
