I bought a PSU a month ago for my new gaming rig, and have decided to get a different GRFX card.

Would a 750W PSU handle without any OC:

i5 2400 @ 3.1Ghz (non OC)
8Gb RAM
1Tb 7.2K HDD
Auzentech X-Meridian 7.1 PCI sound card
EVGA 3Gb GTX 590 Classified
2x 200mm fans
2x 120mm fans
DVDRW Drive

A lot of calculators are giving me mixed readings:

Extreme is telling me 592W
Newegg is telling me 756W
Cooler Master is telling 625W

The most limited in options is the newegg calculator, which leads me to believe it's making some big assumptions on the number of fans and if i OC or not.

"GeForce GTX 590 - On your average system the card requires you to have a 700 Watt power supply unit.
GeForce GTX 590 SLI - On your average system the card requires you to have a 1000+ Watt power supply unit."
