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
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.
