There are unusual noises coming from the power supply unit.
Coil whine is something I’ve experienced before. There’s nothing you can do here. It seems like a bit of hot glue might have come loose, causing that noise. Fixing it would be tricky unless you’re experienced, and even then, swapping out the power supply might be cheaper than replacing the part. It’s just bothersome and doesn’t really affect performance—just your nerves.
Thanks for the assistance. It looks like you'll likely handle it and install another PSU later.
