I have to take down the server to replace the very cheap, generic, $20 "spare tire" power supply with the actual replacement that I ordered.
(Recall that a few days ago, the server's power supply gave a loud POP and ceased working)
The replacement, a Corsair PSU, is supposed to have a 10 year warranty, if that gives you any idea of the quality I'm after.
If the site is too busy tonight (or it's busy right up till my bedtime) I'll do it in the morning.
