Question PC DOESNT TURN ON

[MittronR32]

Today my pc decided not to turn in, the gpu and cpu fans turn on as well a the lights and I hear a click when pressing the power button but fans seem to be quieter then usual and the monitors don't turn on. Yesterday my monitors started flickering alot. I tried cleaning gpu and ram pins, I reset the cmos but nothing seems to help.

I9 12900kf
Rtx 3080ti

32gb ram ddr5
1tb nvme m.2

What might have changed since yesterday, when all was well?

Nothing, I didn't update anything, didn't install anything. No clue. I'm thinking it's the psu.

What is the make/model of the psu?
How old is it?

Parts do not usually break out of the blue.
A bump could have loosened a connection for instance.

If you suspect the psu, borrow a quality replacement to test with.

Corsair l and its about 16 months old, I don't have a way of trying a new one without buying it

Corsair, excepting some VS units are decent.
If you must, to test, buy a quality replacement from a store with a good return policy.
Expect to pay a 15% return penalty if you want to return it.

Thanks, do you think this is the most like reason the pc isn't turning on?
