I've recently bought an AMD Ryzen 7 7800X3D and am facing a troubling issue: my PC unexpectedly shuts down during certain games (like *Ghostrunner 1/2*) when loading screens or level transitions occur. Strangely, there's no BSOD involved, and the only thing logged in the Event Viewer is a "Kernel-Power Critical Error 41" with no additional relevant logs. My CPU temperatures hover between 80-90°C during gaming, which I thought were normal under heavy load and shouldn't trigger shut downs. I haven't tampered with any BIOS settings; they're all on stock defaults, including PBO. Here are my full specs: *CPU: AMD Ryzen 7 7800X3D, GPU: MSI RTX 5070 Ti Shadow, Motherboard: ASUS TUF GAMING B650M-E WIFI, RAM: Corsair Vengeance 32GB (XMP tested on and off), PSU: Corsair RM1000e (recently replaced; I first used an 850W PSU), and AIO: MSI MAG Coreliquid 280.* I've done a clean OS reinstall and updated all drivers and BIOS, but this issue remains. Interestingly, with my previous CPU (Ryzen 5 7600X), this never happened, with the same components. I'm starting to think the 7800X3D might be defective, but I can't pinpoint the exact problem.

Have you checked whether you're plugged directly into the wall or if you're using a power strip? Sometimes older power strips can cause issues like this. Try using a different one or plug your PC directly into the wall to see if that makes a difference.
Honestly, if your cooler isn’t doing its job properly, that could definitely lead to shutdowns. My setup with the 5800X3D stays around 55°C even under load with a 240mm AIO, so it seems like your cooler isn't handling the heat as it should. Make sure you are using thermal paste correctly, and check the cooling setup.
It sounds like your CPU might actually be running a bit too hot, especially for an AIO setup. Reseat your AIO cooler to ensure it's performing well. Those temperatures (80-90°C) are a bit high and could cause instability. Make sure your cooler is functioning properly – also, check if you forgot to remove any protective plastic that's preventing good contact with the CPU.
