FWIW, I usually avoid the cheap PSUs and go for something modest, but a bit better in my client builds (and mine).
Corsair makes nice units, reasonably priced.
One item to note: the fan bearings.
This fan runs with the axis vertical, so ball-bearings are mandatory.
Sleeve bearings fail prematurely when run in the vertical axis.
Back in the Bad Old Days of bad capacitors, it was not uncommon to see the cheap PSU destroy motherboards.
Saving $20 isn't worth it.
There are a number of PSU dedicated testing sites you can Google to find.
These have comprehensive reviews, scope traces, etc, of a wide variety of supplies.
For media servers using standard video, the disk drive count determines the required power.
A 65w Sandy Bridge processor with embedded video is the least of your worries.
Since you are AMD, checking the power requirement is a prerequisite.
