Corsair HX650W enough for 6870 Crossfire?

post #1 of 13
Thread Starter 
Hi all.

I am getting my two video cards for my new PC soon. They will be two Radeon HD 6870's and i am wondering if my Corsair HX650W Power Supply will handle two.

Will it be enough to power the two cards? I also have an overclocked Phenom II x4 965 BE CPU and have 2 sets of Cold Cathodes.

Thanks.

650w is pushing it if you follow AMD's requirements (500w single or 600w dual). I used to have a heavily overclocked Core i7 920 and heavily overclocked CrossFired 5850's with 4 hard drives and never had any issues though.

650W is really nowhere near pushing it. No worries.

I use the same PSU.

I'm more than fine with my specs, and I'm sure my 125w CPU and DDR2 RAM is using more voltage than your current setup.
