Ok, i'm buying a new PSU and my choices are the Enermax EG465AX-VE (W) FMA, EG465P-VE FC, or the Antec True 480w. I'm a little confused about the Enermax psu's because on newegg.com the EG465P-VE FC is 460watts without PFC and the EG465AX-VE (W) FMA (which is more expensive) says on newegg.com that its only like 433watts? The Enermax's have a 70% effiency and the Antec has a 68% effiency. Both Enermax's have 33amp 12v rails and the Antec has a 22amp 12v rail. My only concern is that the Enermax's are 20watts less than the Antec, and I don't really know what PFC does to make a PSU better? So anyone got some ideas? Thanx!

enermax is better but both of them are great power supplies

Ya, I just looked at the Enermax web site and the one that newegg.com has listed as 433watts is really 460watts and has PFC unlike the other one, which would explain why its more expensive. Thats probably what i'll be getting. Would anyone by chance be able to explain what the advantages of PFC is though? Thanx!

I would go with an antec true power, but both are great choices.

why??

I never had any problem with my Antec.

Well, the enermax has 33amps on the 12v rail but only has 460watts and the antec has 480watts but only has 22amps. Which one would be better for me to get?

I prefer Antec, but if you are going to do some serious overclocking, go with the
Enermax because of the higher 12V rail. The Antec PSU still has a fairly high 12V line, so if you are going to do only moderate overclocking, go with the Antec. You probably won't need the 33amp rail though, so go with whichever one is cheapest.

well, I got the enermax. The 12v rail is at 11.74 but that is checking it through software so it'll show less. I decided to see how stable it was so total I had 2 hard drives, 12 fans, a nice oc (sig), 1 burner, cdrom, floppy, 2 case lights and a bunch of usb stuff. I don't usually have 12 fans and a few other things but thats all I could find to see how much it would fluxuate. The 2nd case light was from a car so it takes some good 12v power. So I checked it after booting up and its at 11.80? What is with that? I dunno, I though it was funny though. It is stable as a rock though. no movement on the rails. I still need to check it through hardware though. I'll update after then.
