Question Could the PSU be causing the issue? My PC reboots after a few minutes of gaming.

Hello, I'm having a very annoying issue with my PC, and I'm not sure what caused it or what's broken. I will keep my story short. Thanks for checking this post:

Two days ago, I tried turning off my PC by holding the power button while the monitor was off and several programs (like Chrome, Figma, etc.) were still open. It didn’t shut down right away, so I pressed and held the power button multiple times. Each time it turned off, it would turn back on by itself, so I kept holding the button to power it off again. This happened about five times before it finally stayed off. I went to bed and didn’t think much of it at the time.

The next morning, I turned the PC back on, and as soon as it reached the desktop, it restarted by itself. I unplugged it from the wall and left it for about 10 minutes. After that, it booted up normally. Later that day, I played a few CS matches. The first game went fine, but during the second game, the PC suddenly shut off and rebooted. I got back into the match, but after a couple of minutes, it happened again—no error, just a black screen and instant reboot.

Since then, I’ve tried a bunch of troubleshooting steps: swapped the RAM, removed and reinserted the BIOS battery to reset the BIOS, updated the BIOS, did a fresh Windows reinstall, updated all drivers, ran benchmarks (like Cinebench), and checked the temperatures. Everything looked normal, but the random restarts continued while playing CS.

Then I noticed something strange—when I changed my Windows power plan from High Performance to Balanced or Power Saver, the crashing stopped completely. Now I’m wondering: could this be because the CPU clock stays under 5GHz in those modes? Could my PSU be failing to provide enough power when the CPU is running at full performance? Is it possible that repeatedly forcing the PC off while it was trying to boot back on damaged something in the PSU?

Event Viewer error code: Event ID 41 Kernel

PSU: Sursa Segotep gp600g 500W 80 Plus Gold
MOBO: ASUS TUF GAMING Z790-PLUS D4
CPU: 13600K
GPU: 1050TI STRIX
RAM: 16GB 3600 CORSAIR

Are there any other things I should do or tests I can run to know for sure if it’s the PSU?
Thanks!

Well first of all that certainly isn't a power supply I'd consider using at all.

Balanced should have the same CPU scaling as High Performance under load. If it was just quantity of power then running Cinebench would trigger shutdowns.

This doesn't mean that the PSU isn't to blame for the issues going on. I'd suggest reconnecting all of the power cables just to make sure there isn't a physical connection issue. Also make sure the video card is all the way into the PCIe slot.

Trying another PSU would be the next thing I'd try before doing anything else.

the problem with this error is that it can be caused/triggered by multiple things .
reinstalling the drivers may help (in case it is a software issue)

trying to run your system with just one stick of memory may be another step to try
(just to exclude any ram issues)

but yeah most obvious first guess would be that power supply of yours .
even if you find out it was not causing this issue you should replace it anyway .
