PS4 Pro randomly turns off, not overheating

PS4 Pro turns off randomly I already changed out the fan, replaced the thermal paste and the cooling pads.

when I first bought it couple months ago it would occasionally not turn on and I would have to cycle the power. I did all the mentioned above things and I noticed one of the chips was missing a cooling pad which I fixed when I replaced the rest. after this there were no issues, until several days ago the menus for super slow and laggy. I reinstalled the OS and upgraded the original SSD I put in with a better Samsung 870 SSD drive now it is shutting off randomly. I tried a different outlet and plug which I thought had fixed it until today. I am assuming it is the power supply, anyone else have any other ideas or thoughts?
