The Antec 1200W efficiency is not outstanding, but it's still very high and reaches 91% at 50% and 230VAC. With 115VAC the maximum efficiency is 89%, more than acceptable for practical use. Another interesting fact is that the TruePower nearly attained 80% at low load. With 83% the Seasonic X-Series was a little bit better here, but 80% is still a positive and unusual result for 10%. On one hand they can’t establish a record here. On the other hand, PFC was often over 0.975, even at 230VAC. And 0.999 is an impressive result as well. With 90VAC Antec reached up to 87.14% efficiency at 50% load.

Very silent? Isn't that like a little bit pregnant?computergeek485 - Wednesday, July 7, 2010 - link
haha yea pretty muchshin0bi272 - Wednesday, July 7, 2010 - link
My case has a dual power supply setup... Even running triple or quad SLI I wonder how long it would be before I would need 2 of these. he he heJarredWalton - Thursday, July 8, 2010 - link
Inexpensive Antec PSUs are the same as any other inexpensive PSU: they have to cut some corners. The high-end stuff is generally in a different league.atmartens - Thursday, July 8, 2010 - link
SPCR gives good power supply reviews. The CP-850 and CP-1000 in particular seem to be high quality. The catch is they only fit several Antec cases. In any case, don't just go by brand name.michal1980 - Thursday, July 8, 2010 - link
into a 20amp circuit. Or dont bother having anything else turned on in that room.1200watts, 110% load = 1320 Watts / 84.04% efficent = 1570.68Watts / 120V = 13 amps. Most outlets really only see ~115 volts. Which puts you at 13.65 amps.
Most room circuits are wired at 15amps. Which means with this psu maxed out you have about 230 Watts left over for everything else.
Why?

Why would you be loading it to 110%?michal1980 - Thursday, July 8, 2010 - link
ok, at 100% your at nealry 12amps.Still darn close to the limit of most circuits at home
Simple put, a 15amp circuit can put out 1800watts.

But why are you assuming that people would be running the PSU at 110%.That would be the fault of the owner, not the fault of Antec for building a 1200W PSU.
A triple SLi GTX 480 setup would need about a 1200W PSU, although it wouldn't be pulling that much power.
Not a good idea to even run a PSU at 100% for extended time.
Besides, just put the PSU on its own 15A circuit.

Ha,here in UK we have 240v Yay us :) 3000w at our disposal.
