5 out of 5 eggsIn Production

Pros: 1000w
Works great with the Asus Z9PE-D16 server board.
Loud Beep when/if a module goes bad.
Quiet considering three small fans pushing air.
The green lights.

Cons: Only 1 EPS-12V 8-pin connector.
Where to buy replacement modules?
Price is seriously high.

Other Thoughts: We needed to build and test a server in a quiet office, and once ready send it off to the data center.

(1) You should buy an Athena CABLE-YEPS828 EPS-12V 8-pin Y-Splitter, for two cpu sockets. Even if you only run one cpu, some motherboards, like the Asus Z9PE-D16 require the two plugged in.
(2) You should buy a metered 'switched' PDU like the APC AP7901, so that you can get notified if a unit goes bad.
(3) This PSU is not dead silent, but if placed in the next room, you won't hear a thing.
