PS4 PRO shuts down without warning

I’m having problem with my PS4 Pro cuh-7016b it’s just shuts down on “load “. For example, when in loading into the any game it just crashes, there is no video output, just black screen, however the light indicating that the console is on, but there is no reaction from buttons or controller, i need to plug out the console and afterwards i can turn it on again.

I’ve already tried to replace disks, update software, clean it up and replace thermal paste, and my last idea was that the power supply is the culprit, but i had another ps4 pro and I've tried to replace the power supply from that one and it didn’t help (but there is probability that this power supply was damaged as well).

I’m hopeless right now, anyone any idea what it might cause?
