Confirm my suspicion....

Best power supplies I've come across are the PC Power and Cooling units. Never had one die yet. Just look at the guts of the things..

I second that.

I ordered a 510XE for use with my Supermicro X5da8, and it is superb (albeit a bit noisy, but being made for a server mainboard, the PSU will not be made to be quiet). All voltages are spot on, all the time.
(it was expensive though, esp. as there was an additional import tax on it )

I've heard good things about Seasonic PSUs, both their quality, noise, and efficiency.

I really like my Be-Quiet! Darkpower Pro PSU

and it is indeed quite quiet, has stable rails, high efficiency, flexible cable management, and 3 special fan connectors (which keep the fans spinning for 3 minutes after shutdown)!
