I just got a new video card today and noticed when I'm gaming that the power supply makes a buzzing sound, almost like you can hear the electrical current inside. It only happens when I'm gaming and you have to put your ear close to the tower to hear it. I'm just wondering if this is something I should worry about? My games run fine, temps are fine, fps are at a constant 60 in game. The buzzing bugs me though, any help would be appreciated.
