clicking noise using 220V input power


Recommended Posts

Anyone come across this problem


I'm in Italy. My HX520 is quiet when using a transformer to change the AC from 220V to 110V input. I don't want to use a transformer because the PS is dual voltage, and electricity is extremely expensive when using one.


When I plug straight into 220V the PS makes clicking noises based on the load. Surfing the net it's noisy with extra clicks while scrolling the mouse wheel. When playing COD4 the PS is quiet.


The easy answer is to use a transformer an pay the higher bill. But, the PS is dual voltage so I want it to work.

Its got to be either a problem with the PSU or the power source. I would test the PSU on a different circuit in your home and see if you can duplicate the same issues, and if so, lets get it replaced!


You can use the On Line RMA Request Form and we will be happy to replace it. Be sure to check the box that says “I've already spoken to Technical Support and/or RAM Guy.”
