PSU's aren't always what they appear to be. To paraphrase something I read, "they would claim their product cures cancer if it weren't illegal to do so" which seems to be applicable in a lot of computer marketing, notably PSU's.
To cut through the marketing in PSUland, I pretty much rely on the expertise of the reviewers found through this link http://www.realhardtechx.com/index_archivos/Page541.htm
If you want to minimize your reading and research, I would recommend looking at PSU's from such brands as SeaSonic, XFX, Corsair, Antec, FSP then read the review for that model (or model closest in the series) that will give you an idea of the quality of the PSU (you can even jump to the conclusion page to minimize reading but it is good stuff IMO)
Run far, far away from Biostar. I had one in my first build and I NEVER stopped having problems. If I can impart an wisdom, it is this. Spend some extra $$ for a good motherboard. It doesn't seem important until it is too late, especially if you plan to OC.
