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.

Most houses in the US have 20A circuits, but 15A outlets.Klinky1984 - Saturday, July 10, 2010 - link
A lot of people buying this probably don't need 1200 watts. There is some prestige to having a 1.2kW PSU, but what kind of system is really going to stress this power supply? Maybe if you got one of those 7x PCIe x16 motherboards and created a GPU distributed computing number cruncher, perhaps. But I'd think a more typical tri-SLI setup would have problems pushing 50% usage on this thing.Klinky1984 - Saturday, July 10, 2010 - link
Well, perhaps I underestimated the power-fatty Fermi is.cactusdog - Thursday, July 8, 2010 - link
This doesnt appeal, there are much better options out there with truly silent 140mm fans. Most new high end PSUs are going back to a single rail too.HOOfan 1 - Thursday, July 8, 2010 - link
>most new high end PSUs are going back to single railI wouldn't say that at all....some companies want single rail, but I think MOST is a serious exaggeration.
Why does it matter anyway?

If you buy a cheap supply, its going to be cheap. Regardless of the brand. I have a mid-range Antec and I have been very happy with it. Its quiet, and it weighs about 3x more than the cheaper PSU it replaced.doctormonroe - Thursday, July 8, 2010 - link
I'm not a big fan of having less than a 120mm fan, but the reviewer covered it when he said that you'd hear the rest of the system before a 1200W PSU under load.I'm glad that you've stopped using the charts that were in previous articles (as they were not easy to read and comprehend), but good charts are much better than tables, so hopefully soon you'll figure out a good chart to use.

Yeah...that happens. It happens with anything...especially with electronics.What model was it? If it was REALLY one of their halo products, I am not sure how you came to the conclusion that it was built cheaply.
Of course you have some people who think the PSU is such a simple design and that there is no excuse for a well built PSU to fail. People like that just make me roll my eyes...and usually ignore them from then on.

Antec used to have a reputation for using low temperature Caps that would fail at actual operating temperatures over time. I had assumed that they stopped doing this, but it is possible that they still use this practice.TGressus - Thursday, July 8, 2010 - link
In general the more popular ODMs will have a portfolio of designs. Some better than others. In my experience this is where some of the vendors get away with shady practices. Entry level components get hidden within a shiny exterior, marketed as something they are not and no one is the wiser.I'd like to see the status quo among reviewers/enthusiasts change to focus on relative comparison, and historical performance of the ODM models inside PSUs. As it stands now we tend to focus on a visual inspection, and essentially a second wave of manufacturer QC testing.
When we discuss SSD or GPU we consider the chipset first, and the brand second. This enables the community to make better informed decisions, and allows us to steer trends in product development, rather than the vendor hooride that is the PSU market.
