I've got a question about my rig. I'm planning on buying a second RHD7870, and i know my PSU can handle crossfire. My i5 3570K isn't overclocked yet, and running with stock cooler 3.4Ghz. Now my question is: Can i overclock my CPU with an aftermarket cooler without having a power shortage? Specs: Corsair TX650 @650Watts Intel Core i5 3570K Sapphire HD7870Ghz Corsair Vengeance 1600 4GB x 2 Asrock Z77 Extreme4 1SSD+1HDD 2x120mm Case Fans Thx in advance!
I'd have thought you would. Do you intend to OC the GPU's too or only the CPU? I'll be honest and say I don't know what power draw two HD7870's will be in full load, but from reading Hilberts review of the Corsair CX600M he runs a GTX590 and an I7 870 @ 3.8ghz with no problems and hits around 480W during the load testing.
