My PSU buzzes randomly. It could suddenly buzz out of nowhere during idling. It wasnt the PSU fan. It still buzzes after shutting down the PC. The only way to stop it is to switch off the wall plug.

I have replaced a new unit from MSI but it still buzzes. The buzzing can be heard from 1 meter even if the buzzing sound source (PSU exhaust) is pointing away from me.


PSU: MSI A650GF
GPU: MSI RTX 4060 Ventus 2X 8GB
CPU: AMD Ryzen 5 7500F


Now I have no idea whether I should return the PSU to exchange for a different brand or not.

Use avr or ups. Borrowed from Ur office/ school. U got unstabilise current in Ur electric circuit that yr pc power on. Over time yr PSU caput. Been there done that.

Coil whine

Try the following diagnostics first :-

1. Unplug the Power Cord to the PSU and reseat back ensure its not loose.

2. Replace the Power Cord.

3. Test the PSU with on another PC, if not available then send the PSU back to vendor for further checking.

4. Lastly, get a UPS, around 800VA will do the job. Nowdays UPS comes with Voltage Stabilizer, Lightning Protection etc.


Hope this helps...

Searched around on the Internet and found those cases.

I'm thinking it could be a design flaw from MSI.
