These system restarts appear to occur mainly during gaming, except once when I simply opened the browser. While playing PUBG for an hour, I was suddenly hit by a black screen and then the Windows login screen.

also, you have a 6.5-year-old 650W PSU with a 1080Ti, which leaves very little room for error. PSUs usually output less power as they age.
consider upgrading to an 850W unit for extra confidence, especially if you're using high-power GPUs.
if Amazon is accessible in your area, you can purchase a PSU and return it within 30 days without hesitation.

just keep in mind, things could get worse; you might end up with a full loop of water cooling every time something changes, like I do.
I believe you omitted a sentence about the issue you were facing.
Thanks to the final part, we understand your main concern is random reboots during gaming, while your system performs well on P95 and other benchmarks.
Advice:
Uninstall the graphic drivers using the DDU utility, then reinstall the newest version and test again.
You might want to use benchmarks tailored for GPUs, such as Superposition, and run them multiple times.
Another benchmark, Furmark, is demanding; consider setting your fans to 100%.
Also keep an eye on system and GPU temperatures while benchmarking—this could indicate a faulty fan or poor heatsink contact.
If your system crashes, try using a different power supply.
Generally, faulty GPUs tend to cause artefacts or no response at all rather than crashes.
On the other hand, a power supply with a defective 12V rail can cause your system to fail when the GPU needs power.
I've updated the post with the added sentence at the beginning.
Now I've ran several loops of Heaven Benchmark and no issues. Good frames. At 1080p setting, 137+ frames. 142 sometimes. I will try superposition and Furmark. The curves are set to go to 100% if they meet the temp threshold.
As I say, my temps are good in games and benchmarks like Prime95/Heaven. So I don't think it's the seating of the coolers.
I just don't have another PSU at hand. Nor can I fathom effectively rewiring the whole rig. Is there any other way? What are the sure signs of a failing PSU?

Thanks for the positive vibe, buddy. I got the 1080ti on launch day through pre-order. The FE sounds a bit noisy and isn't very stylish, so I had to install the Kraken mod. I also did the arctic accelero mod before that. I really enjoyed both.
I think I won't go cheap on the PSU. It was top-of-the-line when I bought it for my 980ti five years ago. And for the UK in London, Amazon is definitely my choice.
Before I proceed, I'm going to run Cinebench, Superposition, and then Furmark to check if it crashes during the process. Cheers, man. I'm really happy with this community.
I’d point my finger at your PSU, my friend. The voltage on the 12v rail seems insufficient. Plus, the guru was right—cheap PSUs tend to fail faster if you keep using them. That’s why I advise people to get at least a 650w PSU with 80+ Bronze. Try the EVGA 650w 80+ Bronze; it’s reliable, and my old man uses it without any issues on his 9900k system.
Hi there. I had a strong suspicion it was the PSU. The issue is a Corsair RM650 80+ gold, but it’s now quite outdated. That day was near, and I could sense it.
your 1080ti can be paired with an 850w gold psu from the a-tier selection. it's not that costly. anytime!
