Just because the pc stays on doesn't necessarily mean there's not a power issue, it seems to me like there might be something not plugged in or plugged in the wrong spot.
My advice to check:
Where your ram is seated:

https://i.imgur.com/gyJob7E.pngEnsure your GPU is pushed all the way into it's socket (might be easier to un-seat it, pull the tab back, and reseat for the audible click when it locks in)
Ensure your mouse/keyboard are plugged into the top two USB slots on the back of your mobo
For your mobo power you're mentioning, are you talking about this photo?

Make sure your fans aren't plugged into a RGB socket and that your CPU fan is in the dedicated CPU fan connector (if no cpu fan is detected can power it off)
RAM properly seated.
Tried single RAM.
Tried different RAM sticks.
Replaced every PSU power cable and made sure they're tight.
Replaced GPU.
Mouse/keyboard plugged into top USB.
And yes, exactly that mobo extra 4 pins.
Re-flashed BIOS.
Still the same issue.
Could this be a PSU issue? The only two things I haven't tried are switching monitors and PSU at this point...
