Hi, I have recently built a new computer, and my Corsair HX750 PSU is making an odd buzzing noise. It is always on when the power supply is just plugged in, and it is faint, but noticeable. It is not the fan in the power supply, when it is not running the noise is there, but I am not sure what it is. Does anyone have any suggestions for things that I could stop the noise?

sounds like a bad coil. does the noise increase with more stress on the PSU?
