New Build, What PSU

[bigtalon]

Ok here is what I'm building:

Video Card: Gigabyte 7870
Processor: i5 3570k
Processor Cooler: V8 Cooler Master "Air"
Ram: 8gb Corsair XMS3 1333mhz
Motherboard: Gigabyte Intel Z77 LGA 1155 Dual UEFI BIOS ATX Motherboard GA-Z77-DS3H
Fans: 3x120mm Fans Exhaust, 3x120mm Fans Intake
Hard-Drive: 500gb 7200rpm
CD-Rom: LG - Lightscribe - DVD Burner etc


Now, I do plan to overclock the video card and cpu, but I do not plan to crossfire anytime soon, but may eventually.

Is a good 750w PSU worth it, or should I go with a 850w or bigger ? What would I need to run this successfully, what would you buy ?


I have all the parts, but I have been very picky on the PSU and can't quite pin down which one I should get, if you guys could help that would be great.

You actually dont need thatr much.
Get a quality PSU from Antec, Seasonic, XFX, Corsair or PC Power and Cooling, Silverstone. ~ 600w. At least 80+ bronze quality.

Thanks, I was worried I wouldn't have enough power with 750 / 850, Guess I was thinking it took more , Thanks for all the advise guys, i will most likely be purchasing this 650w today.
