iv upgraded to a phenom ii x4 965BE and my psu's fan has died out on me. loud vibrations then it just slowly stopped. i need help finding a better psu as iv had trouble with ocz in the past. any help would be appreciated.
PSU vendors often make several lines and judging one line against another vendors therefore can be problematic. For example, if I said "Corsair was better than Antec" I'd be correct if we were talking about the Corsair TX series and Antec BQ series. But I'd be dead wrong if we were talking about the TX and the Antec SG or CP series.
Vendors have different lines to target specific market segments so it's not what manufacturer but what line we are talking about. Right now the sweet spots are the 650 and 850 watters as the cost increase to those from the 550's and 750's is marginal.
For comparison purposes , the list below contains performance ratings (10 scale) at jonnyguru.com / prices as per newegg on 12/31/2010 and ones w/ double asterisks (**) made it onto silentpcreview.com's Editor's Choice List meaning they excelled at both electronic and acoustic performance. Note: Just because you see a brand name on this list, never make the assumption that their other lines are of matching quality. Silverstone for example has other models w/ 6.0 and 7.0 ratings. Ones in bold are real buys atm.
Decent 500w would do you for that setup, I've had OCZ for years and had no problems but the Stealth isn't their best offering, ModX and Fatal1ty are better units. Any of these would do you, price order -
