My PSU is whining when it is plugged in and switched on, even if the pc itself is not switched on. I did a little search but most of the problems people are talking about is when their PSU is under load. It never done this before I swapped over to my new case and cpu cooler ( Raven 02 and Frio ) could this be causing the problem ? this is the powersupply in question, http://www.ocztechnology.com/products/power_management/ocz_600w_stealthxstream_power_supply it is about a year and a half old and is powering a stock clocked i5 750 and a GTX470. Could this be bad? I have heard many horrific stories about things dying when PSU's die ...
