Hey guys, I was wondering which psu would be better for a system that has two radeon hd6950's (unlocked shaders and overclocked to 6970) in crossfire setup and a i5-2500k cpu with a moderate overclock.
You are correct in that not all power supplies are equal and it is about 12v amps. However I think you are pushing it trying to Crossfire unlocked 6950s with 650 watts. I would recommend a 750w unit. That XFX unit that Uther linked to is a great choice.
