I received my pc around 4 months ago and only recently realised that I could hear a silient high pitch like noise coming from the PSU after I would shut down my pc. When I turn off the power supply I can no longer hear the noise, I am still unsure whether this issue has been around for longer than I have realised. I remembered I had previously heard a noise when I had problems turning off my motherboard LED's whilst pc was shutdown but I had solved that issue a couple weeks ago. My main questions are; is my pc safe to use still, does it require a new/replacement PSU, and/or are the any fixes to my issue.
Any help is appreciated
