Hi

Just connected my UPS today, the problem is I can hear my Computer PSU buzzing some times?

I am using one of the leads which came with the UPS to connect my computer to the APC Pro 1500.


APC Pro 1500 230V Power Saving Back UPS 865watts

If I move the UPS sometimes I can hear a buzzing from my computer PSU.

When I test my ups by turning the power off, my computer PSU starts buzzing (the ups also starts beeping). I have a UK tech support number for APC. Can't call them until Monday. Any one got any advice for this?

thanks

This may sound daft, but are all the power cables properly plugged in?

I have a Cyberpower UPS - which is great, but sometimes if I move it, a cable moves slightly, everything still works, but it then buzzes at the plug connection.

Other than that mine is completely silent.
