Overclocking intel i7 2600k with 650w PSU

[toxicsalmon]

I'm new to the business of Custom-Built PC's, and have built one already, but recently I've been looking into overclocking as I my motherboard has OC Genie included with it, but before I give it a try, I just wanted to know if there is a specific Power Supply Wattage needed for the Overclock to be stable.

Hardware Config:
Intel i7 Sandy-Bridge 2600K
Asus Geforce GTX 560 Ti
Corsair Vengeance LP - 16GB (4 DIMM slots)
OCZ ZS series 650w 80+ Bronze

I will be buying a Corsair H100 Water CPU cooler before I even try to overclock.

I also have an MSI P67A-GD53 Motherboard

Don't get an H100.
