First of all, sorry if I don't explain well enough, and thank you in advance for helping.
All this started a few weeks ago, I decided to clean my computer case. I opened it, clean the dust (I didn't use anything electronic, and the computer was unplugged), removed the RAM and moved the HDD (testing for future upgrades) and put everything back on it's place.
A few days later, while playing (X-plane 11 in this case), the computer suddenly loss power after 20 minutes ingame. NO BSOD, no nothing. The computer didn't turn on until I unplug the PSU and plugged it again (I discovered later that I can also switch it off and on). I tried again with the same game and same place, and the same thing happened after the exact amount of time.
After looking for it everywhere, I downloaded OCCT, tested CPU, tested GPU, tested RAM (also with windows RAM testing tool), made the power test, and the computer didn't turn off. No temp issues, I removed the RAM again and put it back on its place, I also dismounted the PSU from the cage, removed all the connectors, put them back, and checked the fan was working once ingame. I tried playing and everything was fine, so I put the PSU back into the cage.
At first, I thought everything was fixed, but then, I tried other demanding games (Microsoft Flight Simulator, Euro Truck Simulator 2, GTA V, Digital Combat Simulator), and the issues came back. The computer now doesn't shut down during gaming, BUT only randomly after closing the game. There is a lapse of 5/10 seconds, and then sometimes (and I say sometimes because is not happening always) computer loss power. To reproduce it, I have to play one of those games for at least an hour, It doesn't happen if I play a few minutes. More demanding games (MSFS, XP) will lead to reproduce it more frequently than other less demanding (ETS 2), but at some point all demanding's games cause this.
So today I decided to run OCCT test for the entire hour. CPU one was successful, and the GPU one was too, but just after the GPU test finished, computer has shut down again.
I have a video of the OCCT monitor during those power loses, but it doesn't show anything relevant. Just everything going to idle, and a few seconds later, the shut down. I also discovered that I don't need to unplug and replug the PSU to restart the computer, It will restart alone after a few minutes since the hard shut down.
I hardly find the causes for this, most of topics I read point to a PSU problem, but I would appreciate some perspectives, since only happens in this situation.
The computer is 4 years old, the specs are:
