Hello,

I have a GTX690 incoming in which I don't plan to get a 2nd one for SLI.

Currently my specs are:
i7-3770K
DZ77GA-70k
8GB DDR3
500W Enermax PSU
H100i AIO Cooling

What PSU would I need in order to handle the GTX690 under these specifications? I can potentially get a PC Power and Cooling 750W Silencer from my family member, would that suffice? Would it allow for minimal OCing with the 750W silencer?

Thanks.
