    5.1v

    Still buzzes underload

    On the current set up its GPU load that causes it. Voltages seem fairly stable though when the buzzing starts it does flicker a little.

      The toasty PCB definitely makes me think of a Deer!

        The buzz is coming from the larger of the two coils (12v I presume?) on the secondary side.

        What can be done about this, would swapping it from another PSU be ok?

        Failing swapping it would covering it in hot glue be ok

          i would try painting it with epoxy.

          do not use superglue - ever.
          it vaprises when it gets hot.

            I think it would be worth a shot to replace the 5VSB output diode. I had a PSU a long time ago that had 5V on the 5VSB but would not power up. I swapped out the 5VSB output diode and it powered up.

              I have put a good smothering of epoxy over it, will see if it cures it!
