Question PC will restart all of a sudden from time to time, without BSODs! Help plz!

Hi! Been a while since I last posted on here, but I'll do my best to explain!

For a while now, my PC has restarted from time to time without any warnings or BSODs.

So far, I've tried these steps without any success:
1. Made sure my PC wasn't overheating.
2. Made sure my drivers were updated.
3. Ran a virus scan, malware scan, adware scan, etc.
4. Ran windows memory diagnostic tool.
5. Reseated RAM/placed in other slots.
6. Disabled automatic restart.
7. Updated my BIOS.

My specs are:
-Asus ROG X570 Crosshair VIII Hero WiFi
-Ryzen 9 5950X (not overclocked)
-EVGA RTX 3070 Ti FTW3
-EVGA Supernova G6 650W fully modular
-Corsair Vengeance RGB Pro 32GB @2933
-Corsair H115i Elite RGB
-Crucial SSD 4TB
-Samsung 970 EVO Plus 1TB
-Samsung 970 EVO Plus 2TB
-Samsung 970 EVO Plus 2TB

I don't know what else to do. 🙁 I'll include the last event viewer log & some extra screenshots. If anyone can assist me with this, it'd be greatly appreciated! Thanks in advance!

How old is the PSU in your build? I'd try and source(borrow, not buy) an 850W reliably built PSU and see if that helps alleviate the issue.

I'm not sure how old the PSU is tbh. 🙁 probably 2 years or so? Sadly, i'm not able to borrow another PSU to test out atm. I'll try to save up enough money to get a new one.
