I need to know if i can run crossfire on thes GPU Sapphire Radion HD 7970 GHz Vapor X 3GB on this PSU XFX ProSeries XXX Edition 750W PSU 80 Plus Bronze.

Thanks for the help :)

No, a 750w PSU is not enough of dual 7970s. You would need at least 850w+

+1 dual 7970´s a single 7970 asks a power supply from at least 600W minimum, to let a system work with it, so if you put in 2 in crossfire then i would suggest  take a look at a 900W or a 1000W psu just to be  fully safe.

you could, but, depending on the rest of your system it may explode. if you use the 750w psu for the gpus only, it'll be good for a couple years

it's only a 250w card

AMD claims that a 7970 card gonne use upto 300W so that would make that in crossfire they gonne use 600, but i saw some tests, where the power consumption of the whole system was over 700W so i would suggest at least 850W or more, like i said  900/1000W to go realy safe
