I'm having a frustrating issue where my computer completely powers down while I'm gaming. I recently upgraded to an Asrock Steel Legend 9070XT GPU and decided to jump back into Battlefield 6, which I hadn't tried on this new setup before. I played through The Division 2 and Control on mostly max settings without any problems, so I thought I was good to go. But after finishing a match, while just sitting on the menu, my PC suddenly shut off like I pulled the plug! I shrugged it off as a fluke, but then it happened again while playing Control, and later, it wouldn't even make it past the intro of Hogwarts Legacy before powering off. On the bright side, I can still play Warframe and Forza Horizon 5 maxed out without issues. I've tested the RAM, CPU, and GPU using OCT, and everything seemed fine. I also updated my BIOS and the AMD Adrenalin software, but I'm still at a loss. Any help would be greatly appreciated!

It sounds like your power supply unit (PSU) might be the culprit here. Ensure that it has enough wattage to support your GPU and CPU, especially under load. You can use a PSU calculator to double-check your requirements. The Asrock Steel Legend 9070XT pulls about 304 watts, and your AMD 7800x3d can peak around 162 watts. Adding everything else, you should ideally be looking at a PSU rated for at least 700 watts. If you're already above that, then it could be an overheating issue.
Overheating could also be a cause, especially if your PSU is working hard and is underpowered. Check the temperature sensors for both your CPU and GPU to see if they're running too hot. It's worth keeping an eye on those logs, as they can give you insight into what's happening before the crash.
You might have a similar problem to what I faced. Reseating the RAM and all cables helped me out when my PC was shutting down randomly. Sometimes connections can loosen over time, especially after building a new rig or upgrading parts. It’s an annoying process but worth a shot.
Have you checked your BIOS settings? Sometimes, stability issues can arise if settings are not optimized. If your PC worked fine with old settings, try reverting to default settings or ensure nothing has been altered that could affect performance.
You might want to feel the PSU after it shuts down. I once had a PSU fan that was dead on arrival, causing it to overheat during heavy loads. If it feels excessively hot, that could be your problem.
