From the 80 PLUS website:

The 80 PLUS performance specification requires power supplies in computers and servers to be 80% or greater energy efficient at 20%, 50% and 100% of rated load with a true power factor of 0.9 or greater. This makes an 80 PLUS certified power supply substantially more efficient than typical power supplies and creates a unique market differentiation opportunity for power supply and computer manufacturers.

It’s been my observation that the majority of technical questions here could be answered with a quick google. Maybe we need a fluther question on why some people ask questions that are easily answered with google? :)

Benseven actually googling this question hot on this web site first so…........
I would have to say that google is only as good as the web sites make it to be.
Without this question answered here I would have never found this great site.
