Could you post your system components (with model #s)

If you had a similar issue with the power button, then disconnect the power button wire from the motherboard to rule that out.
You could short the two power pins with a flat screw driver to power on the PC.
A failing PSU could turn on and even power some components.
I would try another PSU.

It isnt a button issue i think its a psu because i tried to power it on ( plug a green and black wire together) and it doesnt work when i had the power button i tried this method to see if its motherboard or psu problem and when i shorted green and black wire the psu started which in this situation it doesn’t hopefully its a psu problem and not a cpu or motherboard

Make sure to unplug all wires connected to your computer before testing the PSU.
If you jumped the 4th and 5th pin on the PSU 24-pin connector (while the clip was facing you), and the PSU did not power on then the PSU has failed.
