Need a PSU for an old rig

[Dizik]

I'm trying to hobble together some old parts so that I can play around with Ubuntu, but I think my old PSU has finally bit the bullet. Most of the parts are fairly old (Core 2 Duo E6600, 4GB DDR2, Audigy 2 ZS, couple of old 160GB SATA drives), with a fairly recent video card (GTS 450). With that being said, I'm not sure exactly what I would need for this setup. Any help would be appreciated.

Im guessing a 400w PSU would be fine for that setup. What makes you think your old PSU is dead?

Disregard....the computer booted. For whatever reason, it wouldn't work when I hooked up the front panel connectors manually. This is despite me unplugging, double and triple checking to make sure that they were connected properly. When I use the connector block, everything works great. Odd. Ubuntu 12.04, here I come.

Usually means that either something in the front panel assembly is loading down the +5VSB rail so much that the board can't return "power good" to the PSU, or else something in the front panel connector assembly has a ground short.
