I have a Corsair CX750M PSU, and whenever I'm in a game, it emits a noise that I can only describe as a buzzing or even a soft sizzling. If I alt-tab or quit the game, the noise stops immediately. From what I can tell, it doesn't seem to be coil whine, although having never experienced coil whine, I'm not 100% sure. The PSU is pretty new, only a week or two old. I actually don't mind the noise but I'm worried of possible danger to my other parts.
