The amps are what matter, there is a table on PSU label, it gives amps values, best with at least 18 -20 on the +12v for your CPU, make sure its a good make, some PSU are useless, give ratings that are peaks and not sustainable. If it fades out after a few mins, that sounds like a heat prob, is heatsink tight to CPU, and enough paste, but not to much, about a grain and a half or rice size of paste is required, if you are using Artic Silver or metal pastes, be very careful. AMD warranties are void with metal pastes. Some, yours included, have metal nodes on top which will short with metal paste. The AMD64 bit chips do not have these nodes. Is your CPU fan OK?, connected to the Cfan connector. Other thing is you may have a bent CPU pin. Although, a short on mobo, flakey PSU, or a flakey Dimm slot are prime suspects, try RAM in another slot, just use 1 stick, If RAM is incompatible with CPU and board, ie Registered, ECC, Dual channel or something, when board wants Non ECC, unregistered, single channel, can cause this. I have seen boards post first time and appear fine, but on reboot, the RAM settings are altered and it won't post . The normal cure then is to remove ALL cards and MEM, reset CMOS, allow to discharge. Then use a differant Ram stick to force a reset of stored values. Your not using a USB Keyboard and mouse are you.? Which Mobo is it?
Good luck
Mike .

The latest CPUs need a lot of amps on the +12v lines, the AMD64s need at least 18 amps barebones just to post. but 30amps will run them OK.
Its a XP3200+ and the hardware monitor shows (showed) that the 12V voltage
supply is 12V+. Wouldnt that imply that there were sufficient amps? The
other day I soak tested it for some 12 hours and thought all was hunky-dori.
Next day I switched on again and it died after a few minutes. Hasnt booted
since then. Same behaviour as just before I changed motherboard, CPU, RAM
and PSU! Ive tested with two different, relatively new HDDs, both of which
have been extensively tested on another machine and found to be ok.
