Game consistently crashes my whole PC.

[Marvin]

As the title suggests, while playing Black Mesa it often times crashes my entire PC into a forced restart.
During normal gameplay it "only" crashed once every couple of hours, causing my PC to automatically shut off it's overclocking (which helped for a bit) but after entering Xen and now specifically in Gonarchs Lair my PC crashes after MINUTES of playing.
Here's what I tried:

-verified integrity of game files
-reinstalled the game completely
-turned off Overclocking
-deinstalled Half Life 1, 2 and DM and then reinstalled Black Mesa
-Updated ALL of my drivers
-played the game in Potato mode and in windowed
-restarted my PC (duh)
-turned off Overclocking and essentially gibbed my PC into only using a fraction of it's power
-tried straight up speedrunning through sections that made my PC crash

Here's my PCs specs if they help
PC itself is an Alienware aurora R9
Windows 10 64bit
Processor: Intel i7-9700 3.00GHz
16 GB Ram
NVIDIA GeForce RTX 2060

Your power supply is most likely having trouble with the game itself if it forces your whole computer to restart.

Thanks for the feedback, I'll try changing a few settings related to my power supply around to see if that helps!

Killed my PC after literally less then a minute.
I should mention that my PC manages to play RDR2, GTA V aswell as even the mess that is Cyberpunk 2077 at at least 200+ fps on ultra with no problems what so ever yet somehow Black Mesa on Gonarchs lair is too much for it to handle. I'll try playing on a new safe file in case my current one is corrupted, I'll also try a few beta versions to see if that changes anything

If the power supply is faulty, you can't just 'change around some settings' to fix it.

Well I do have the option to run it at maximum power or "energy savings mode" (had it in energy savings mode) and after changing that to maximum power usage it turns out it killed my PC after simply starting the damn thing. Currently in the process of reinstalling the game for the 100th time.

Everyone has that option, but that is beside the point I was trying to make.
