I'm having an issue with my PC where it randomly restarts while I'm playing high-end games, specifically after around 2 hours of gameplay. Here are my system specs: I'm using an AMD Ryzen 5 7500F CPU, a BIOSTAR B650MT-E PRO motherboard, an RTX 3080 GPU, 16GB of DDR5 RAM at 5200MHz, and a 900W power supply. My main SSD is a WD PC SN810 NVMe. I've noticed that when I run stress tests like OCCT, the system is stable, but the problem only happens under high GPU loads during gaming. This issue logs as Event ID 41 (Kernel-Power). Could this mean that my PSU is failing to handle the load, especially as it heats up?

It sounds like your power supply is struggling under load, especially since the restarts happen after an hour or so of gaming. When components heat up, they can lose efficiency, which might trigger protections in your PSU and cause that sudden shutdown. I'd suspect the PSU is the culprit here. If possible, testing with another power supply would really help confirm this.
Check your temperatures while gaming! The RTX 3080 is great for undervolting, and keeping things cool is essential. Also, I'm curious about how you're powering your GPU. Are you using separate 8-pin connectors or daisy chaining them? This can affect stability too.
Sounds like it could definitely be the power supply. I'd recommend looking for something reliable based on a PSU tier list. You might not need to go over 1000W; a solid 900W unit could be fine too, especially if it's a good brand. But don't compromise on quality!
