PC keeps restarting/rebooting on game startup

[warraich91 0]

I have PC with following specs
   Intel Xeon X5670
   Lenovo X58 board
   20 GB DDR3 RRAM
   Rx 590 8GB
   Window 10
I have played games like Sekiro, God of War, Spiderman (both), GTA V, Doom Eternal, Furi, NFS MW etc on this setup smoothly.
But certain games, when started, force restart / reboot of PC. This has happened when I started games like Ghostrunner 1/ Ghostrunner 2. Recently I installed Lies of P and as I start the game, again PC suddenly shuts down and then restarts.
I have tried everything like disabling internet / anti-virus, reinstalling game / drivers, disconnected any devices, even reinstalled clean Windows.
(PC details are attached here and some in comment)
Kindly help.

Google Drive is not public.

Also, it's most likely a PSU or GPU hardware issue as the PSU's power surge protections might be triggered by unusual power draws from the GPU.

See for example this video as something that might cause that kind of issue:
