Re: Computer randomly powering off
Definitely sounds like a bad power supply. Generally speaking, if you build a PC and you can't name the power supply by official name, it probably wasn't a quality part. Also, if you can hold it comfortably in one hand, it's probably not a good power supply. The best power supplies will be h e a v y. Not break your hand heavy, but they should have some heft to them. Do you know if yours was a brand name PSU, or did you in fact pay only $20 or $30 for "500 watts" ?
