System shuts down when graphics card works hard
System shuts down when graphics card works hard
Hello! I recently switched from a 1080ti to a 3080ti FE. The graphics card was purchased used on eBay ("one year of light use"), and the seller seems trustworthy. Once installed, everything worked smoothly until the GPU hit heavy usage, at which point the system would restart. It wasn't always consistent—sometimes games would run for about 15 minutes without a reboot, other times it would take up to two hours. I checked forum discussions for common problems: the power cable isn’t daisy-chained; there are two separate cables. All connections from the 12-pin adapter to the PSU are secure, with no dust or debris affecting them. The maximum draw across components stays around 650W, which is lower than the PSU’s 850W capacity. The PSU looks clean, and the fans aren’t blocked. Temperatures never exceed 80°C on either CPU or GPU. Drivers are up to date. I ran Valley to test for similar issues—it produced comparable results, sometimes restarting within 15 minutes, other times running smoothly for over three hours. I also tried setting the GPU’s power limit to 50% in Afterburner, but it didn’t affect the restart frequency. The attached images show the Event Viewer after the crash, with no error messages beforehand. Thanks for any advice or help—I’m running out of ideas for troubleshooting.

Do you have someone whose PSU is rated for more power than yours? I thought the 30 series NVIDIA GPUs might experience big power surges briefly.
You're really pushing it, man. The 3080ti beats the 3090 in raw power. When your PSU hits its limit, you just don't have enough juice for all the other parts. That's why you need to restart. I suggest upgrading your PSU to something over 1000 watts so it can handle those big power spikes.
You don't have to use a more powerful PSU, just one that can manage the quick power surges. I'm not sure if the Thermaltake model includes additional safeguards in its build.
