HX620W starts getting constant buzz noise


Recommended Posts

I just noticed last night that my HX620W emits out low constant buzzing noise (electrical buzz from coil or transformer?). It's not from the case fans. I disconnect them all but the buzz noise still there. The next thing I did was to validate if the PSU fan causes it. I use a pencil and poke in to stop the PSU fan and the buzz noise still there. But if I have my exhaust fan runs at 12v (max rpm), I don't hear the buzz noise anymore. I guess the fan noise is overlapping the buzz noise.


Is the buzz noise normal? But then I again I just started to notice it.


May be I plug the modular cables into the wrong connector ports?
