Ornolf Posted January 16, 2016 Share Posted January 16, 2016 Hello, everyone. When I push the power button on my PC I hear the single click from my PSU and system starts. Also there is single click when system shuts down. It sounds like some sort of switch turns on and off inside the PSU. No clicks or other noise during workload. Is this normal?
