Oh yeah, another feature to look for for some people is how loud it is.
Can't beat a good deal on a decent power supply.
The only problem I've foudn with some reviews and what made it so difficult to make an informed decision, is that there are so many review sites, and they don't all review all the PSUs, some of the reviews are a few years old, yet the PSU is still an active product, but since th ereview is so old, and may be the greatest PSU since sliced bread, and as such could have recieved very high ratings, yet since then many more could have come out and been reviewed and now be much better. What I haven't been able to find is a good single comprehensive source with all the recent and latest PSUs with ratings along with relative comparisons of desireablility. Now that would be nice. I've seen something close to that with some CPU coolers.
