Efficiency in accordance with the 80 PLUS specification:


Efficiency under different load profiles:


It becomes clear during testing that Enermax has earned its 80 PLUS Gold certification. We saw impressive results in the 87% to 91% range in our energy efficiency measurements, both at 115 as well as 230 volts. This very solid showing was confirmed in other load measurements, with efficiency falling somewhat only at very low power loads. The overload test shows that Enermax's Pro87+ still has plenty of reserves. Even with an overload of more than 20% of the power supply's stated output, it still provides stable voltages. A small weakness was revealed when testing the hold-up time, though. Here, the power supply even falls short of the ATX specification requirements. This is an unnecessary drawback given the otherwise very high quality.
In the sub-$150 price class, the Enermax Pro87+ is a genuine highlight. The high energy efficiency under mid- and full-power loads qualifies the power supply for use in rather high-end PC systems. The Enermax Pro87+ is less suitable only for very low-power computers, as the energy efficiency diminishes under very light loads. However, for such PCs, this PSU would be overkill, anyway.

anyway I did not notice voltage stability measurements and a "hot box" test.
Other then that, it's a pretty quick analysis. Wish you'd open them up to actually see what components they used in their primary and secondary circuits.

I'm happy that yet another site thinks highly of the CM Silent Pro series; I'm using the M600W currently.
according to most people that i know, seasonic is the very best brand that make quality psu for the money
newegg has a Seasonic S12ii Bronze 520w for just $69.99

and according to reviews it is the very best power supply in its price range(it even beat the Corsair HX 620w)

But yea very nice read, was expecting some more cheaper PSUs tbh though, the vantec ions seem to offer good price/performance, at least here in new zealand, dunno if you get them in america
in my opinion, if i am buying a 500w psu
my main concern will be efficiency
since i wont mind doing some crazy overclocking or tri-sli or quad fire over a 500w psu
also look at this very interesting result that i have found
a Core i7 920 + GTX 260 @stock under PRIME 95+ Furmark has only a maximum power consumption of 371w

and in real life usage i bet you wont even get close to that power consumption even when overclocked
With that aside, in my opinion finding a value PSU is about weighing price and quality. Although the Pro87+ was a monster when it came to efficiency, it was still said to be available for around $140. First, that's a bit much for a budget/midrange PSU and secondly, I couldn't find that particular PSU anywhere online. I found the 600W variant on newegg for around the same price...but it's not the same PSU.
Pretty much the same goes for the other PSU's. I couldn't find them at any reputable online dealers (newegg, tigerdirect, zipzoomfly, etc.). And I do realize that it takes much time to do a review like this, but it seems like some of the more popular brands have been left out. Even if they don't have an 80plus "Gold" PSU at or around the 500W level. At least then you'd have a baseline for a so called normal efficiency power supply.
I did a lot of research when I purchased mine a couple of years ago when I last built a ground up system. I settled on a corsair VX550 and have been thoroughly impressed with how it's handled my moderate gaming system. Now this is a personal preference, but I've been so pleased with it, I doubt if I will go to another PSU label. But anyway, that's my $0.02.
you probably figured out what I was trying to say...but meant a good PSU allows components to last longer. Sorry bout that.
Very interesting article, thanks
The review you posted is from 2007...that power supply unit is old tech. Get with the times.
That's not what the picture says
Be patient guys, this is the first time, right?

Other than that, this looks very useful.
