I prefer to also use product reviews in making a PSU selection.
Several websites that do a good job of reviewing hardware are: Overclockers Club, Legion Hardware, AnandTech, Tom's Hardware, Benchmark Reviews, HardOCP and TweakNews.
If one is able to find more than one review of a particular brand and model I find that's a big help also.
One last note, having been an electronics geek for decades, a good rule of thumb is that the heavier a power supply is, the better quality it generally is. This means larger better transformer, bigger better quality filtering capacitors, better quality resistors, heavier heatsinks, heavier gauge wiring, etc.
