2 out of 5 eggs6 months and power supply died

Pros: did a great job running the system overall when it ran properly
perfect size for my system
quiet fans

Cons: had several times it would cut out imediately upon power on started at about the 2-3 months of having it. it would also sometimes power down randomly losing any work at that time. pulled apart the whole system thinking maybe some sort of short only to find out nothing was wrong and problem still persisted until it completely died and will no longer power up at all.

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.

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.
