Overclocking CPU and GPU

[jon0]

Hello, i recently bought a Gtx 780 and im wanting to overclock it as i've seen what the card is capable of.

I'm also wanting to overclock my I5 4670K CPU .
I'm wondering what a good PSU would be for this as i plan to do a heavy overclock.

A 650-750w unit from Antec, XFX, Seasonic will be plenty.
