750W for GTX 590

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)
1Tb 7.2K HDD
Auzentech X-Meridian 7.1 PCI sound card
EVGA 3Gb GTX 590 Classified
2x 200mm fans
2x 120mm fans

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.

    You should be fine. The test system they used in this review uses an i7 920 and similar components to your system. Bottom line, under full load it only used 461. So I believe you should be fine with your 750W PSU.
  3. According to Guru3D:

    "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."
