Your power supply might be aging; your motherboard could be failing too. Reset the motherboard's CMOS to check if it resolves the issue. If you're comfortable with tech, use a multimeter to test your PSU. You can also run stress tests like prime95 for CPU and GPU to see how your system handles power draw. These tests aren't conclusive, but OCCT can help you log any findings from your experiments.
Thanks for your message! It seems you're short on multimeter skills but are taking steps by researching and testing your system. The CMOS reset, render tests, and stress test all came up normal. Temperature stayed stable and the PC didn’t crash. For a PSU, it’s hard to say without more details—consider it safe to wait a bit longer unless you notice recurring issues. Keep up the good work! 
Performing a CMOS reset might have resolved your issue. I’ll keep an eye on whether the problem recurs. The stress tests were a good sign. The PSU seems to be aging; if it still works, it’s fine to wait a bit, but in the end, I’d consider replacing it. Here’s a PSU tier list:
