I built a new gaming rig about 6 months ago in the winter. I have a PNY nVidia GTX 770 card (http://www.amazon.com/dp/B00CZ7Q028/ref=pe_385040_30332200_pe_309540_26725410_item) with a Corsair TX 750W power supply (http://www.newegg.com/Product/Product.aspx?Item=N82E16817139006). The thing runs great except for when I play games full screen, there is this loud and persistent buzzing noise that goes through my headphones. My friends in my skype call say they can hear it too. I know it is not coil whine because when I take my headphones off and listen to my computer, it doesn't buzz. With similar problems in this thread, I read that it could be interference or that my psu is working way too hard / on max load when playing games. However, I think the 750W psu should be enough for the GTX 770 right? I don't know... I need your guys' opinions / ideas on what I should do please.
EDIT: When I plug in my headphones to the back audio panel, the whining is almost completely gone. It's barely audible / not at all. But, I'm worried since I can hear the whining through the front, but not the back, could the whining still be hurting my computer? Like, is the whining indicate a new psu or am I fine?
