well im looking at replacing my ultra 500w psu. (ready for flaming). Its been loud recently and i think the fans going out. Its not that stable on the 12v and 5v rails so yea cheap pos. Anyway back on subject im looking at getting a corsair psu such as the 620hx or the 520hx. Are there any others <150 USD that are on par with these or are they the best? Also heres the specs of my build. e6300 oced to 2.6ghz 8gb ddr2 800 oced to 856 p5n-e sli mobo evga 8800GT 1x 80GB sata hard drive (maxtor) 1X 320GB sata hard drive (WD) ultra 500w pos looking to eventually get a better processor such as the e8400 or similar. Would 520hx be enough or do you all think i should go ahead and grab the 620hx? Thanks
