Nah, over 80% efficiency is the same as bronze rated.
Sorry I'm a bit out of the loop on windows 8. Is it a better performer for gaming?
Ha, well there's 2% - but this isn't 80 plus rated. It's rated at over 80 but can't get an official rating as it doesn't work in the US.
Though the jonnyguru site gives the OCZ a very good score, and that's probably the best PSU review site. So I'll change my suggestion to that. Just don't tell Potty.

There are better Psus for a similar price and have longer warranty.
