Question Computer will not turn on ?

I have been gaming on my computer just fine until earlier today. I see my screen turns off because I'm inactive, so I go to the keyboard and press some keys and wait a minute but nothing turns back on. The computer was still running, so I didn't think anything was wrong. I press my reset button and wait a few minutes, and still with no video output, which usually only takes a few seconds. I turn it off with the power button and try turning it back on again, but the power button doesn't work.

So I pull the power button off of the pins and try it manually with a screwdriver, and nothing happens. I unplug the psu and reset the cmos battery, and try again, nothing happens. The lights on external devices and internal rgb does flicker, but does not stay on. I tried a different power cable too. I checked to make sure everything was seated properly. Anyone have any more troubleshooting suggestions?
 
Sounds like the PSU may have died.

Please post full system specs including PSU make, model & approximate age ?
I was also thinking psu problem. I wanted to test it but I can't find documentation for which pins I need to jump in order to see if it is even responsive.

Cpu: i5 12500

Ram: GSkill V-Series 3200 Mhz 2x16 GB

Mobo: Gigabyte B660M Aorus Pro AX

PSU: Aresgame 750W Fully modular 80+ Gold

System is about a 3 weeks old, and the PSU is a few months past a year old
