What PSU will I need?

[Net]

If I go with the i7 875k, gtx 460 and I want to overclock my proc to ~4.1-4.5GHz what power supply will I need.

I'm building up my system here: http://forums.anandtech.com/showthread.php?t=2112363

will 650w work or do I need 750w?

650W would be plenty, good quality of course.

Around 600w will be more than sufficient

I would consider the XFX 650w... They are Seasonic made, look cool, semi modular, 5 yr warranty and are Priced right. I paid $87 plus shipping on sale for the XFX 650 in my 2nd rig. Its overkill for it but I know it will last for future upgrades.

I know I'm running 2 of them... But I have 5 PC's running in my house (yes 5 I know) and everyone of them are using a Seasonic based PSU without issues.

When I first built the Gaming PC I have below with only 1 GTX 470 I originally picked up a 700w Modxsteam OCZ and it struggled to run my system at MAX load. Quality just wasn't there. I added a 2nd GTX 470 and a XFX 850w and no issues at all!
