Hello I built a few days ago my first gaming pc and I noticed my psu makes a buzzing noise sometimes and stops.

I found out that it's most likely coil whining and it tends to happen when someone takes a bath with the water heater.

I enabled erp in bios bcuz I read it could help. What else can I do in this situation and is it ok to turn off the power supply at night?
