Another testament to the old "watts mean nothing" saying.  This is a pretty good review from HardOCP.  The best place I know of for anything related to power supplies and reviewing them is http://www.jonnyguru.com/

The other major sites like AT are usually not as thorough and detailed, but that's to be expected when comparing a broad spectrum hardware site to a specialist site.  Still, it's a good review from H.

I'm just happy that HardOCP started testing power supplies in this manner since nobody else had been, and I like the fact that if it sucks, they'll outright say so and why.  The power supply is THE most important part of a computer and too often is overlooked as an important component (beyond the wattage sticker).  Too many computer manufacturers throw in just whatever they get at a cheap cost.  It's no good having a top of the line motherboard, CPU, video, etc, and then have a crap PSU, but how do you know if that PSU is good or crap?  Look at the sticker?  Read the box info?  I don't think anyone would deliberately put an engine from a Yugo into a Ferrari or a Hummer, but you know the dealers would if they could get away with it.  I've seen bad power supplies take out computer mainboards and hard drives when they fail, so the more torture testing they do the better.
