I had made a post earlier about a buzzing sound that I thought was coming from my video card (http://hardforum.com/showthread.php?t=1535707). Upon closer examination it seems like it is coming from the PSU. Should I RMA my PSU? I have only had this power supply since January this year. It doesn't make the sound all the time, but at the time of this posting it has been buzzing for about 15 minutes. Here is a sound clip.
