HD6950 x2 Crossfire PSU

post #1 of 7
Thread Starter 
What's a good PSU for running 2x HD6950's (unlocked to 6970 shaders and overclocked to 1000MHz Core Clock) in Crossfire?

Thanks,
My System

Really? I would think that I would need 750W minimum for Crossfire on these cards.. even with a good PSU? (I am also overclocking my CPU too, but this will be for a new build, so maybe an Intel 2500K)

I would reccomend a solid 750, but remember... those cards are not OS X compatible. If you want osx. Compatible go 5870's

Yeah, I have pretty much decided that I'm gonna need to build a separate rig for gaming on It's OK though because it may be time to upgrade the motherboard to DDR3 and crossfire support anyways. I will keep my sig rig for OSX and use a KVM to switch displays between the two computers.

Here is the full build that I am looking at with maybe a second 6950 2GB down the road:

Lemme know what you think!

Oh and do they need to be the exact same HIS brand models for Crossfire to work or can I get by with any 6950 2GB?

You can use whatever cars you want. Crossfire can be between a 6970 and a 6790 if you really wanted. That would just be foolish though.

700W is good and will have some headroom. Depends on your budget.
