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.

The XFX units are more efficient and feature modular cables.
Any one of those units would be fine.

Uther I heard its not about total wattage. It's about the amount of amps put out by the 12v rail. For instance some 750 w psus are worse than 650w psus and some 500w psus are worse than 450w psus.

I could be wrong though. Please correct me if I am.

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.
