Installation of the new GPU 3080 Ti causes the system to restart repeatedly.
Installation of the new GPU 3080 Ti causes the system to restart repeatedly.
Hello. I recently purchased a 3080 Ti GIGABYTE Vision 12GB and upgraded from a 3060 Ti INNO3D LHR. My issue is that after the upgrade, my PC restarts immediately under heavy load (in games) but doesn’t crash when idle or while using apps. I haven’t experienced any problems with the 3060 Ti. I own a noname 720W Argus PSU; manufacturers suggest a 750W PSU, yet some users run the card on 650W and even a friend uses a 3090 on a 650W easily. My belief is that higher-quality PSUs can better handle the 3080 Ti compared to mine. Have you heard that they perform more reliably? I’ve tried undervolting via afterburner, which slightly improves stability but still causes restarts and reduces performance to around the 3060 level. All cables are secure, the PCIe slots are correctly connected, the GPU and RAM are re-seated, I reset the BIOS, used DDU to uninstall and reinstall drivers, and my BIOS is up-to-date. My system runs a B450 Gaming X, 5600X, with two 8GB G.Skill DDR4 modules at 3600MHz.
Choose a reliable 850W power supply. Running it on a 650W unit with ease isn't enough. Your system uses premium components, so don't cut corners on the PSU—it should be the core that powers everything smoothly. It's probably more capable than advertised, even if the label says 720W, which might not reflect its true performance.
650W sufficed for gaming setups with CPUs up to 105W and 3rd generation GPUs until 2016. Now a solid brand 750W is the baseline requirement. I’m unsure why you’d spend the same price on lower wattage: Antec, Corsair, Thermaltake, EVGA. Overclocking or UC only causes instability and reduces hardware lifespan.
They say 650W is fine, but most people don’t know what they’re talking about. Your power supply isn’t well-known and isn’t top-notch either. It won’t manage the sudden power bursts from a 3080 Ti graphics card. Don’t skimp on PSUs, particularly when you need strong performance—using one that’s too weak could cause serious damage, even start a fire. Invest in something much better, like a 750W or higher, preferably 850W for optimal results.
Thanks to all the responses, I've purchased a Corsair RM850x and plan to use the corresponding card.
