Will my power supply be able to crossfire?

post #1 of 6
Thread Starter 
Will the psu on my sig rig be able to crossfire 6950 1gb?
My gut feeling is no, but what do you guys think?
And what would be the minimum psu I need to perform the crossfire?

Thanks!

It should be alright if you don't go for any crazy overclocks.

You should be fine. The sensible PSU recommendation for 6950 Crossfire is a 650W unit. While your EA-650 is labeled as a 650W unit, its +12V output is only 540W. A pair of 6950s would require between 250 and 300W under a normal gaming load, so that leaves you with enough power for everything else.

It should be fine. Usually high quality PSUs (such as yours) can handle significant overloads (200W+) very safely. You have absolutely nothing to worry about.
