Power Supply Clicks When Turned On

Why does my computer make a clicking noise when I turn it on?

Your computer is full of fans to dissipate heat inside the computer – a fan over your processor, a fan on your graphics card, even a fan or two to blow all that hot air out of the back of your computer. This sort of clicking may be caused if the fan is clogged and can’t turn properly – or if a fan blade is broken.

Why does my PSU click and not turn on?

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.
