Question Need help finding out what this click sound is coming from my pc

[Lawin_000]

Every time I turn on or turn off my pc I hear a quiet click noise, I'm scared if this is bad because I don't wanna risk my pc. Could anyone tell me what it could be? I'm thinking its either the power supply or motherboard.

My specs:
Motherboard: Gigabyte B365M DS3H
CPU: i7-9700k
RAM: 16GB DDR4 2666MHz (2x8GB)
GPU: GTX 1050 Ti
PSU: ADATA XPG CORE Reactor 650 W 80+ Gold Certified Fully Modular ATX Power Supply (I bought this new 2 days ago)

Clicking can only be made by moving parts. The easiest thing would be to make sure a cable didn't drift into the way of a fan blade. If you have HDD they can click when seeking and such. To a certain level it's normal, but generally not if really loud and notable. Pumps (AIO) can make noise as well.

Beyond that, there is nothing else I can readily think of that CAN make a clicking noise.

It only does the click once when turning it off or on though and it only happened when I changed my PSU

FFS.... It's an inrush current relay. Welcome to the world of quality PSUs.

Yep that's the relay in the PSU opening and closing when you turn on and off the system.

Totally normal. Nothing to worry about.

Is that bad?

Glad these fellows got you sorted.

It just seemed an obvious guess since you had the machine apart just before, something I have learned from experience.

Of course not. It's normal for 99% of the PSUs on the market.
