Highest Efficiency 500+ watt PSU?

[futura2001]

Just wondering (mostly because I have to replace an Antec TP-480 with a 24 pin PSU soon) what the most efficient PSU that provides more than 500 watts is?

Antec Phantom 500 or a Seasonic unit might be what you're looking for.

The Seasonic S-12 series is known for its high efficiency and low noise. They make a 500w and 600w model, both with 80+ efficiency.

I agree - Seasonic S12 PSUs are among the most efficient with around 80%-85%.

seasonic s-12 all the way

Seasonic S12, some high watt Zippy models, the new Fortron Epsilons, and 850W+ PC P&C are all at or above the 80% level.

Well, looks like I am going to go with an S12 500 or 600 watt PSU since everyone likes it so much.
Thanks guys.

just a word of warning the 20+4pin power cable is a bit shorter then the average PSU at 16 inches. Aside from that it's a very solid PSU with steady lines and whisper quiet.

PCP&C 510

Zippy PSUs.

HHmm , no one hear mentioned the NeoHE 550 (85% efficency , Active PFC) . Maybe this is due to the bad reviews coupled with certain Asus boards ???

But ,for me , Ive got two NeoHE 550's , both running in Opty 165 systems (Abit AN8-SLI/ Asrock Duel) , and have NO complints what-so-ever . Units are VERY VERY quite , solid rails , SLI ready , runs cool and modular design an added plus in my book .
