Great deal...Great item...600 watts and a plus 80 rating...only thing that would make this better is if it were modular for better cable management...cant go wrong with the name for the price...This PSU had an adequate number of cables and sufficient power output for my PC, which I would qualify as more than a standard PC but not quite a gaming rig.
