nVidia GTX 460 PSU choice help

[UiriamuChan]

I have chosen three PSU based on the fact that they are on sale on Newegg as a combo with a video card which I plan to not use and sell because I'm getting a nVidia GTX 460.

Components:
ASUS Maximus III GENE LGA 1156 Intel P55 Micro ATX Intel Motherboard
Core i5 2.66ghz Lynnfield-750
2x2gb DDR3 ram
nVidia GTX 460

PSU:
OCZ ModXStream Pro OCZ500MXSP 500W

Rosewill Green Series RG530-S12 530W

CORSAIR CMPSU-400CX 400W
http://www.newegg.com/Product/Produc...82E16817139008

I know Corsair has good reputation. OCZ is okay, but I'm worried about the amount of amps going through the 12V as it's the lowest of the three. Rosewill has the most amps going through each rail, but I've heard their reputation is pretty bad.

So which one should I choose?

rosewill is a def. no-no, i would say the corsair one, but that card isnt exactly lenient on power use. 400 might do it, but your losing that buffer area.

i guess the one thing ocz is good for is their PSU's, but just last week my cousin's OCZ psu blew up (almost litterally)

your best bet would prolly be the corsair. they are good quality and should be OK even if you are running close to 400 watts, it just depends on the rest of your setup.

from benchmark tests @ tomshardware, that card uses about 260 watts under load, so if you have a 95-125 watt CPU, you should be fine.

Best answer is "none of the above".

Nvidia recommends a minimum of 450 watts for a 460, and the card requires two 6 pin PCI-E connectors. The Corsair fails on both criteria. I don't trust OCZ or Rosewill PSU's.

This is the best buy out there right now if you grab it while the promo code is still available:

I thought from reading the stickies that the wattage didn't mean all that much as long as I was getting enough amps.

ehh, opposite is true... too an extent.

pretty much any PSU would provide enough amps to keep a system happy. amps relate to physical work, or basicly how much energy can be moved at once, the higher this is, the more stable you would be in a system that demands bursts of power.

wattsi s a little harder to explain, but basicly its how much actual power the psu and output. watts are the basic unit of power. they are the most important factor in a psu.

This is true, but the Corsair 400 is not suitable. It's not set up for two PCI-E connectors.

If you are spending $200+ on a video card, it makes sense to spend an extra $20 for a power supply that will definitely handle it reliably.
