Hi guys,

I'm building the following system:

Gigabyte GA-880gm-ud2h motherboard
AMD Athlon II X4 640 cpu
4gb (2x2gb) Crucial DDR3 1333
1 Samsung 1.5tb SATA-II drive
1 Bluray drive
1 (powered) external HD

This won't be a gaming machine so I don't intend to put another graphics card in other than the on board graphics of the motherboard. I've been burnt with a rubbish insufficient power supply and have been looking at the following two PSUs:

Corsair CMPSU-500CX ({power+supply}%2bc{420}%2b)
OCZ StealthXstream II 500W ({power+supply}%2bc{420}%2b)

Both seem to provide what I would think is sufficent power - both have dual 12V rails, the Corsair has 34A on 12V and the OCZ has 36A.

Would either or both of these be sufficient?

I'm bearing in mind here that I've already tried two PSUs in this build; one rated at 450w (17A on 12V) which wouldn't even allow the system to POST and another rated at 500w with I think 24A on 12V that crashed after around 2 minutes of uptime in Windows XP. So I'm erring on the safe side.
