5 out of 5 eggs8 Units, no problems

Pros: We have purchased 8 of these for 1U servers, starting over a year ago, and haven't had any problems. Solid, reliable.

2 out of 5 eggs50/50 isn't bad.

Pros: NA

Cons: Deployed two of these ~6 weeks ago. One has died already.

Not good for a server part.

Other Thoughts: Does anyone do any QA anymore?

5 out of 5 eggsgreat, even for slim desktop usage

Pros: I'm using this ps to power a custom built sff desktop. It's nice and slim, with more than enough juice to power an overclocked i7-2600k. One great feature of the ps is the P4 cpu power plug. There is a single 4 pin connector plus the two combining 8 pin plug, so that's three plugs total. All cables were long enough to reach to where they were needed.

Cons: Wish there were threaded mount screw holes on the bottom, rather than just on the ends.

Other Thoughts: Fans are nice and quiet, unlike many 40mm fans. Even under a high power load of 50% the ps stays cools and the fans quiet.
