see, that's what I believe, a less then popular brand PSU I wouldn't trust. I had a 480 Watt for my old pentium D820, it had 1 12V rail @18 Amps, everything ran stock and had a BFG 6800GT OC AGP in the system, should have had no problem, blew the card 2 times (lifetime warranty). Nothing else let go mind you, just the videocard, so I changed PSU for an Enermax 375 Watt (friend gave it to me), had less issues with that PSU and well didn't have an issue with it. Strange, but I still would have preferred more overall wattage so I did that with a quality PSU with more wattage then I needed this time and have not had any issues what so ever, of course not really pushing new PSU now so that helps. I guess you get what you pay for as the saying goes, oh and on another note, I noticed my cousin is going through the need to change PSU every 6 months because she buys no name PSU, and not to say she has a powerful machine (2.4HT socket 478, intel board, using all onboard components, 160Gb HDD and 1 DVDRW, no videogaming and the PSU she gets is 500Watts with 1 22Amp 12V rail)
