I upgraded my GPU from an RTX 3070 to an RTX 4070 Ti, and now my PC is crashing randomly, especially when launching games or even just sitting in menus. The crashes are accompanied by a black screen, the GPU fans ramping up to 100%, and the system becoming unresponsive, requiring a hard reboot. According to the Event Viewer, it reports a Kernel-Power Event 41 without giving any specific error logs. I've already tried reinstalling drivers, adjusting BIOS settings, and monitoring temperatures, but nothing seems to help. My suspicion is that it might be related to my power supply. It's a labeled 1000W Apevia model, but it's older and not ATX 3.0 compliant, which could potentially struggle with the power demands of the new GPU. Has anyone resolved similar issues by switching to a higher-quality ATX 3.0 power supply?

I've heard mixed reviews about Apevia PSUs. From what I've seen, they often rank lower in quality. If possible, get a brand with a solid reputation for reliability—like Corsair or EVGA—to help stabilize your setup. It really can make a big difference!
For sure, a good PSU can make a huge difference in overall system stability. Do your research!
It sounds like you've done a lot of troubleshooting already. The spikes you mention are definitely a sign the PSU might be struggling. Switching to a quality ATX 3.0 PSU (850W or higher) can often help with newer GPUs that have high transient power peaks. Many users have resolved similar issues this way, so it could be worth looking into!
Yeah, I've heard that many budget PSU models can't keep up with the demands of newer graphics cards. It might save you a lot of headaches in the long run.
Definitely consider upgrading! I had similar problems and a PSU change fixed everything.
Good point! I’ll definitely look into some recommendations before I commit to a new PSU.
