[ale] Server PS shuts off for no reason

[Benjie]

You can still open a 1U case and plug an ATX PS in.  You are probably
right that you will end up with a RMA.  Since it is running with a
live cd, I would be inclined to think that it is a bad PS. You aren't
really using the hard drive, and hard drives pull a lot of juice on
boot and during heavy I/O.
