Should I upgrade my PSU

[HingeDisc07]

I plan on getting a Corsair H100, do you guys think I should upgrade my psu?

Heres what I got:

CPU: Intel i5 2500k oc'ed 4.5
Motherboard: ASRock P67 EXTREME4 GEN3
GPU: MSI R6870 Twin Frozr II crossfired
HardDrive: SAMSUNG Spinpoint F3 1TB
Ram: CORSAIR Vengeance 8GB 1600 ddr3
PSU: CORSAIR Professional Series HX750
Asus DVD burner
Hyper 212+

Case is a Corsair Carbide Series 400R which can hold the fan above the motherboard. Am I fine with the 750 or should I look at a quality 850 psu?

Thanks!

that is a pretty power hungry system, If it was me i would upgrade my psu.

You wouldnt want a power problem in that case!

Why? the HX-750 is an excellent psu and cranks out over 900W.
No need to guy.

When all else fails - simply run the numbers for an unbias, accurate determination of the PSU power and amps required to run your current or future system config. and then check the output and objective test reviews for the PSU(s) that you have or that you are interested in. The link below will show you how easy it is to do.

BTW the Corsair H100 won't draw all that much power but I do not personally recommend the low end H2O coolers like Corsair because they have been reported to leak and cause expensive hardware failures that do not occur with a performance air-cooled HSF.
