Hey guys, I have a question, I got an Corsair GS500 psu from a friend that is unstable, sometimes it works, sometimes it doesnt. He bought another psu. I played with it for a bit, but it is still unstable. He doesn't have the receipt anymore. The psu has been announced in 2011, and it has 3 year carry in warranty. Do you think they will accept the rma? Does anyone have experience with this?
