The power supply came with a case that a friend of mine bought. I have used it for less than a month. It is a Turbolinx model LC-A420ATX so i assume that means 420 watts. It has 28 amps on the +12v rail. In speedfan it is showing anywhere from 13-13.2v. I unplugged one HD and the big case fan and the voltage stayed the same. For some reason it shows 2 +5v with one at 4.8v and the second at 6.85v.
