Oh, no, it still makes noise. But it shouldn’t shock you!
I hot glued just the yellow transformer inside the power supply, and it helped a little. I was going to hot glue the rest of the board and try to lower the squeal a bit more, but haven’t gotten around to it yet.
As is, when the power supply is in the back of the cabinet and everything is closed, once the game boots up, you can still hear it. Lowering the brightness changes the pitch, so I would lower it to where it is the least unpleasant for you, then put it in the back of the cabinet and close everything up and see if you can live with it.
I think the bit of noise it makes is worth it for the look, but that’s a decision you have to make on your own.
At least the under cabinet LED strips are quiet.89402DDF-97E7-48E4-9E13-129322D2ECFF (resized).jpeg
