Summary: I've purchased a few of these 600w units, and have never had a single problem. They are usually one of the least expensive PSUs available but still come with a nice warranty and a good number of connectors. Supposedly there are reliability issues, but I have yet to see any. I'll be buying more of these.
Summary: I picked this up for a spare power supply to have on hand in case of issues with ones in my several builds around the house. I used it to power up my cooling loop for several hours for a leak test. It's pretty quiet overall and not bad looking. With mail-in rebate it works out to about $30 so can't go wrong with that. Glad I have it around for a spare for testing purposes.
Pros: Cheap net cost with mail-in rebate, Reliable, Fairly Quite
