Seasonic, Antec, Corsair, XFX, Enermax/LEPA, or (new) FSP are the ones I'd consider. I've seen some good test results for the PCP&C units, but despite their name they are very loud under load. m 0 l Related resources 850w Corsair more than enough for new build? - Forum Do I need 850W ? - Forum XFX 850w XXX loud, need replacement!! - Forum I need a psu what is 850w for under 100$ - Forum Do i need 750w or 850w PSU? - Forum Can't find your answer ?

The original Silencers were loud, the MK II units probably aren't seeing as they (all except the 950W version) use large 13.5cm fans with maximum speeds of 1500RPM and noise rating of 29dBA. Although with a $250 dollar budget I would definitely buy something else.
