what psu do i need for 2x radeon hd 7870's

I want to build my pc and i was just wondering if a corsair cx 750w is enough.
Im getting a intel core i5 3570k processor i will overclock to about 4.4ghz I want to run 2 gpu's on it (amd radeon hd 7870's) in crossfire but idk if that is enough power

Rather not get Xfire off the bat, its usually a much better idea to get the single most powerful card you can afford unless you are going the Nvidia SLI route... Xfire has what we call micro-stuttering, meaning the FPS is not stable in a sense.

I agree with Novuake. The 7xxx series in Crossfire suffers from micro stuttering and frame latency issues.

If you do decide to go with those cards then 2 x HD 7870s in Crossfire need a recommended 600w power supply.

So your Corsair is fine.
