I am guessing you have OC'd the CPU. What stepping processor do you have? GO or B3 and what CPU voltage are you running your OC at?
What block config do you have the memory in? 2x4Gb, 4x2GB, etc.
Is the sound card in a PCI slot?
What fans do you have in your case? Size and quantity. Any fan controllers? I take it as you don't mention it that you are on air and not WC?
Do you have any USB connections that draw power?
Any DVD/Blue-ray, etc? Please specify type and quantity?
And finally, any cathodes?
Am I right in thinking that ur GFx takes two 6-pin connectors? And if so, the specs on your PSU indicate that it has just two 6-pin connectors and also 2x 8pin. Is this right?
Or you could just follow Spree's link and work it out for yourself. But as my last question makes reference, it is not just about raw power but availability of connectors!
