Problem started a few days ago when I turned on the power outlet (UK) to a extension cable I used this socket hub to connect my PC and my monitor. The wall outlet when I turned it on started to make popping sounds, going from barely noticeable to a loud pop. But then the PC works fine without any problems or noises. My house sockets are relatively old, don't know exactly how old.

I got a brand new PC a month ago, parts came in 18/12/20, and my power supply unit is the ABKONCORE TN600W.

When I turned on the outlet today, it was the loudest it was ever been, and then my PSU started to have a popping/hissing electrical sound. I turned it off immediately. Then I switched the socket and switched the extension cable to another one and it stopped and it seems to be working currently, with no loud noises heard and since I am typing this on the PC.

I want to diagnose the problem and know what the next thing I should do next, should I use the warranty of the PSU or replace it? Or is it OK?

Current operations on the PC seem to be working as normal, and no abnormal sounds on PSU as of typing this.
