I don't know what you meant, but Cooler Master's eXtreme Power 500W and eXtreme Power Plus 500W is a "true" 500 wattage unit, it's just a bad built unit therefore should be avoided. A 380W-400W unit labelled 500W won't give more than 23A-29A on the 12v rail.Yeah. Unless you have a 380W psu labelled 500. (sm1)
@mazkraven, as hasanJ said not a worthwhile upgrade. Gather some more funds and upgrade the whole goddamn rig!
