to all you who have the same psu as i do. I have an antec 902 case and when i turn on the computer, i do not know what is causing that irrating sound. at idle i believe it is my psu fan that is making all this noise and i dont know why. is the 650 hx suppose to be this loud at idle? is all this noise coming from my case? i currently do not have a powerhorse gpu, just a crappy one.
