Question PC rebooting when playing games. Faulty PSU?

My pc is restarting whenever I try to play a game. In the past, this happened after a few hours of playing, but now my pc can't take even 20 minutes.

At first I thought the problem could be the high temperature of the CPU, so I changed the thermal paste but it was no use.

During my research I was told it could be a ram problem, so I used MemTest86 but no errors were found. I tried to look at the windows event viewer and the only thing that caught my attention was the error: Kernel-Power 41 0x8000400000000002, but that just tells me that windows shut down the wrong way.

My best evidence for the problem was a test using OCCT. I tried different tests and all were well succeeded, even under stress the temperature of my CPU did not exceed 80 degrees celcius, but when I try to perform the power test my pc reboots.

Does this indicate that my PSU is not working properly? My PC works normally when I watch movies or use the internet. Only when I play or do the powert test does it restart. I don't have another PSU to test and I would like to be sure before buying a new one. I've already tried a fresh instalation of Windows 10. Could my mobo be the problem?

My build:
B450 Bazooka v2
Ryzen 5 2600
RX 580 8GB
2x DDR4 8GB
EVGA 550 Bronze Plus

If they restarted only when you do gaming and working normally when do other things, sure that the power issue. Mobo issue rarely causing restart.
