That's an excellent powersupply. Output for +12v may not be as high as some of the others, but it's very consistent and reliable. There's a few reviews on it over the Net and they've all been favorable. I've bought about 3 of these powersupplies over the last few years and they've all worked great. This model is AMD approved all the way up to 1ghz, but I think AMD may need to update that info as when the info was posted, the 1 ghz was the fastest available.
Speaking myself, I have this PS running in my main system right now and I haven't experienced any problems with my 1.1ghz T-bird/KT7-Raid.
