In troubleshooting an old system I ended up purchasing a 500W PSU. It didn't solve the problem and now I have components for a new system on the way. I never took the +12v rail amperage into account. So based on the component list below will i be ok with 20A on the +12 rail.

Gigabyte GA-EP35-DS3R mobo
Intel Core 2 Duo E8400
EVGA 8800GTS 320Mb
2Gb Corsair XMS2 DDR2 800
80Gb WD SATA2 HD
250Gb Seagate SATA1 HD

Its a generic unit I purchased at a local wholesale shop. And since it isn't going to work. Any recommendations that will get me running and not break the bank.

As far as brands go, look at the tier chart in "Forums, CPUs and Components, power supplies, a sticky by Jake Barnes called power supply facts, and at the bottom of the page is a tier for PSUs.

As far as wattage goes, with what you list and I assume some other hardware, you should look for a PSU between 550wt to 650wt. That should allow for some additional hardware later.

Would an Antec Earthwatts 500 Watt ATX PSU work? It has 2 +12V rails that will support 17 amps each.

That should work with what you have. The Earthwatts 500 is a good PSU. The only potential problem is that it won't leave much room for expansion, and if you ever wanted to go SLI or Crossfire, it would be too small. But only you can determine if you ever want two video cards.

Excellent. I can get an Earthwatts 500 locally. As far as the idea of SLI or Crossfire goes. I'd need to upgrade more components than the PSU to get capability. All in all I don't have enough time to game to make it worth the added expense to go to an SLI or Crossfire system. Thanks to everyone for the assistance. I have a good handle on where to go from here.

Imagine your bank if you have to replace all of your computer parts because you were cheap with the PSU.
SeaSonic or it's OEM supplied partners. PCPower etc.
