PC shuts down repeatedly due to high frame rates.
Have you verified your temperatures during high FPS? Look in the task manager for unusual activity. Review event viewer logs. Restore BIOS settings, including DOCP. Revert any GPU adjustments such as power and voltages, and check the Nvidia control panel. Ensure the GPU is correctly seated. If possible, test with a different GPU since you lack integrated graphics. The PSU might also be the cause. 850 watts isn't excessive for the system, though it should function properly. Consider downgrading to Windows 10.
The temperatures during high FPS were around the low 60s. Most components in BIOs are stock except XMP, though I've reset to default settings. I ran DDU and the only issue in the event viewer was an error about an unexpected PC crashing kernel power event 41.
You might be experiencing strong spikes from the GPU, drawing up to three times its normal power for a brief moment. This activates the overcurrent protection on your power supplies and causes your computer to shut down. Possible fixes include purchasing a more capable PSU, reducing the GPU's voltage to lessen those spikes, or underpowering the GPU.
I’ve heard about this too—possibly the PSU isn’t handling the load anymore. Two weeks ago I kept gaming at 200 fps, and my PC hasn’t ever restarted before.
Your PSU is wearing down gradually. What's its age? Were you playing the same game two weeks prior?
Your PSU meets the basic needs but is showing strong transient spikes. Switching to a 1000W unit will resolve the issue. Alternatively, lower your card's power cap to around 80%—it should maintain over 90% of its performance. (Apply Asus GPU Tweak for this adjustment.)
It hasn’t been that long for a PSU, and I’ve been running the same game nonstop at 200 fps for a week. After it restarted after rebooting, it’s been happening every other session. It doesn’t seem like the 850W is the issue—it’s been working fine for three years. I just need to confirm it’s a PSU problem before spending over $200 on a replacement.
I can examine the dump files for any useful hints. Visit C:\Windows\Minidump and verify if there are any minidump files present. If they exist, return to your Windows directory and transfer the entire Minidump folder to the Downloads folder (you may use the desktop if OneDrive isn't available). Compress the copied folder and include it in a message. Please adhere strictly to the guidelines provided by Windows.
It really comes down to the exact card you have, since these spikes are also affected by how the board partners deliver power. I’d still recommend lowering your voltage. You probably won’t notice any drop in performance, you’ll use less energy, and you won’t stress your power supply. I’ve tested an RTX 3090 with a 750W PSU without issues that way.
