HOW TO

Why does my PSU make a *click* sound when I turn on my PC?

Most of our power supply units (PSUs) have an inrush current bypass relay that makes a *click* noise when the PC turns on and off. This is considered normal and not a defect.

If your PSU is making loud repetitive clicking sounds after you turn your PC on, contact Customer Support.
