[SOLVED] Upgraded high-end system. Crashes while gaming under good temps

Recently I upgraded my old system with a new CPU, motherboard and case. Unfortunately since then I have been having issues while gaming. Mostly after 10-45mins the PC instantly powers off and automatically restarts after a minute or so. The power button is unresponsive during this minute. Temperatures are pretty good, CPU sits at 40°C and GPU around 50°C. My guess would be problems with the PSU, but it was working fine in the previous build a while ago (never had crashing issues back then). The only change that I'm not sure about is the 8 + 4pin connector for the CPU. At first I added an extra cable to the PSU and connected them both. I read mixed results about the second 4 pin not being required so I tried both, but the PC crashed in both cases.

While upgrading the PC I re-used the (m2) drives, PSU, GPU and RAM from my old setup. At first I just booted my old startup disk and tried installing the new drivers. It worked but got me the same crashes. Now I'm on a clean install with updated drivers & windows and am still having the same results.

I checked all the cables, graphics card & ram is seated correctly. The only thing I can think of is that the PSU cannot handle the new CPU/motherboard/CPU cooler (with xmp enabled)? But I'm at a brick wall because I think 850w should be good enough right? Is there anything else I can try or check before getting a new PSU?

Thanks a lot for taking the time to read this!

Common causes of sudden shut offs/restarts, and what you can do about them:
1)Missing or corrupt Windows drivers
A)Make sure PC is clean - run antivirus and antimalware programs.
B)https://support.microsoft.com/en-us/help/4026529/windows-10-using-system-file-checker
C)Reinstall Windows - especially after changing motherboards

2)Memory failure
A)Memtest86 free version: https://www.memtest86.com/
It does take a few hours, so run it overnight.

3)Insufficient power supply
That's an old platform from 7-8 years ago. 5 year warranty. It was great budget unit back in the day - it's 'meh' now.
A)Replace it. That's all you can do here.

4)Overheating power supply - it refuses to turn on for a set period of time
Either due to fan failure, or the loads are simply too much for the internal components to deal with anymore...
A)Same as number 3.
