Hi. I have a 15 year old 650w psu that was running strong abt 9 hours ago. I turned it off for the night using the switch on it. When I went to turn it back on this morning I noticed it was crackling before I even touched it. I noticed that it doesn’t matter what the power switch is at and it crackles whenever I plug it in. I also have tried 3 different cables and it is still doing it. I know the other 2 work fine as they are in use atm
Edit: could be the switch, I’m testing it now
