You can probably find some bottom feeder power supplies that don't have PFC, but I wouldn't trust them to power a fan. 80 PLUS certification requires PFC (active or passive) to correct PF to 0.9 or better, and I wouldn't dream of ever buying a PSU, even for a system I don't care about, that wasn't 80 PLUS certified.
Speaking of 80 PLUS, SeaSonic's 80 PLUS Platinum certified units, which requires 90%+ efficiency, are due out in September. I think I may finally upgrade my S12-600. > -----Original Message----- > From: [email protected] [mailto:hardware- > [email protected]] On Behalf Of Bino Gopal > Sent: Sunday, July 31, 2011 10:11 PM > To: [email protected] > Subject: [H] PFC (power factor corrected) PS for PCs? > > > So for all you guys building computers, are all power supplies PFC nowadays, > or do you specifically only buy the ones that are PFC?
