Thanx fellas, its not mine, but the PSU is http://www.newegg.com/Product/Product.aspx?Item=N82E16817171018
Tell your friend to get a new psu and stay away from Coolermaster.
Their models below the Silent Series are quite frankly junk.
Antec,Corsair,Seasonic,XFX,make the high quality units.
OZC makes good quality units for those on a budget as do Antec,and Corsair.
Alot of people buy really good gear and cheap out on the psu.
Huge mistake.
That particular unit is an older model with a 500w max output,i seriously doubt it's even close to that in actual delivery.
Modern units have the output rated as continuous and the max is usually much higher.
My Corsair HX-750 is listed as 750W continous watts and maxes out over 900w.
