Question Is my Motherboard broken?

[03_szust]

UPDATE: Solved. Hello, yes, it's me. I am the problem. After further testing and plugging everything out and in again everything seems to work. Most liekyl cause is a not completely plugged in main cable into the PSU.

Hello Guys
Today I had to replace my CPU because my old one was damaged by the intel razor lake vmin shift bug. After installing the new CPU i tried turning on the PSU and heard a sharper, more intense click in comparison to just flipping the switch, the RGB LED's and the GPU power LED turned on for a second and then turned off again.
SInce then I have tried a lot of things to see if anything worked (testing the PSU, reseating the CPU, checking the connections, removing the GPU, clearing CMOS) and after doing the first one the RGB and the GPU power LED turned on again for 2 seconds but then turned off and since then I got nothing.
How likely is it that my Motherboard is fried? Motherboard is ASUS ROG STRIX Z790-E gaming wifi and CPU is intel i9 13900k.
Thank you for your help.

Turn pc off completely PSU etc remove plug from wall hold power button down for a few minutes see if there's charge left in capacitors.

It's possible the PSU is damaged. Or motherboard.

How did you test the PSU? Just testing it for power on can't eliminate a PSU problem; it can only verify a completely dead PSU.

tried...testing the PSU

you tested the system with another power supply?
or tested this unit in another system?
just verifying that a PSU powers up doesn't mean that it can still properly power the connected components.

include the make & model + it's overall time in use.

I tested the PSU with the help of this: https://www.corsair.com/de/en/explo...ly-units/how-to-test-a-psu-power-supply-unit/ as it is a corsair RM850x and it behaved as expected. I can however go and test it with a multimeter.

Update: went and tested it with a multimeter: zeros across the board.

Further Update: after trying a bit more now it reads all values as intended. PSU seems to be fine

We couldn't hear the click, but it's very possible that the sound you heard was the PC as the capacitors providing power to the PC for a fraction of a second as they drained off. If the PSU isn't connected, you may do that intentionally to make sure the capacitors are drained as much as you're able to.
