PSU faulty?

[jave808]

Hi,
My PC has just started to play up. I go to hit the power button, PC power LED lights up, I hear a 'click', then it powers down. If I hit the power button repeatedly like 3 or 4 times, PC will fire up and boot.

Is my PSU about to go? It's not a cheapie - Seasonic Focus 650W. I have other supplies, so may need to test them out.

Thanks.

If you are OCing... set it back to normal and try it.

Or, it could be PSU, Motherboard, memory, etc.
Process of elimination... try different psu, try with one stick of memory (try one, then try with another). Any lights or beeps from motherboard?
When you get it running, check device manager to see if any devices are acting up.

It would help if you listed your system specs.

Nah, not overclocking. If anything, I've set the speed in BIOS to 3.6GHz. I did this to control CPU temp when crunching.

Running Linux Mint 20, so no Device Manager.
