Ummm...not that I know of...try neoseeker.com...they search info on all tech stuff...as far as i know only enermax PSs gets the most reviews...even the 550w one. maybe there's not just anything to review...and they end up being about how it fits in the case or how easy it is to install which is pretty useless to me. There was one though...about the enermax 550w...they measured the voltage fluctuations on it...which was still pretty useless to me.
