I'm experiencing crashes with my GTX 1080 Ti under heavy loads when I play games like CS2 or ETS2. Typically, it happens after about 5-10 minutes of gameplay, even though the GPU temperature remains below 78°C. I don't have any issues with benchmarks, and Fortnite runs smoothly on Performance Mode with low settings. This makes me think the crashes occur when the GPU is near 100% capacity. I've tried using older GPU drivers and lowered the power limit in MSI Afterburner, which only delayed the crashes. My power supply (PSU) is 600W. Could the PSU be the culprit here, or is my GTX 1080 Ti starting to show signs of failure?

If the game freezes and sends you back to the desktop, that might indicate a power supply issue. Have you checked if it shuts down completely or just crashes to desktop?
It might be a problem with your PSU. I have a GTX 1080 running at 0.96V with an overclock up to 2073 MHz and my PSU is 650W. My GPU stays around 65-72°C under load. If your power supply isn’t delivering enough juice, that could definitely cause crashes. Alternatively, it’s possible that your GPU isn’t stable at the current overclocks. Try underclocking or increasing the voltage to see if it helps stabilize it. Also, failing GPUs often show artifacts, and since you’re not seeing those, it could lean towards a power issue instead.
OK, thank you so much!
Given that it's an older card, it might just be showing signs of wear and tear. Sometimes, aging hardware can fail under stress even if it doesn't seem to in other situations. It could be worth testing with a different power supply if you have one available.

The game freezes and then takes me to the desktop.
