Device shuts down unexpectedly during gameplay.
Device shuts down unexpectedly during gameplay.
I've noticed my main computer shutting down unexpectedly only during gaming sessions. I've reviewed the logs, but no clear clues were found. System temps are normal, GPU runs in the low 80s, and CPU stays around 60. I also tested Prime95 and Furmark stress tests simultaneously for two hours without any crashes. This usually occurs only when playing BG3; I played Sims 4 for hours without issues, but it typically stops within 30 minutes or so. I've already changed several things: reinstalled Windows, unplugged the sleeve cable extensions, reinserted RAM, swapped out RAM modules, removed the GPU riser card, replaced the power supply, and changed the motherboard. Despite these efforts, random shutdowns still happen, especially during BG3. I'm unsure what else to try now.

Help suggestions would be appreciated.
Use MSI Afterburner to reduce GPU TDP to 80% instead of the default 100%. This helps prevent power spikes that could trigger OCP issues. An 850W rating should suffice, though both the RX 6000 and RTX 3000 models typically need a power supply that handles overspec.
You've explored various RAM, motherboard, power supply, and Windows configurations. At this stage, you're focused on the GPU and CPU. When the system shuts down, does the Windows Event Log show any errors? Are fans and other components halting before a full power cut? You're also curious about the GPU's heat dissipation—Agall mentioned it should handle spikes. Did you switch to a newer or larger power supply when testing?
AIB minimum suggested for 6800 XT models lies between 800-850W, where the issue arises from millisecond 200% TDP spikes. This can affect even PSUs rated up to 850W. The concern isn't the power delivered, but insufficient capacitance and inductance in higher-wattage units. When the power supply shuts down abruptly, combined load measurements of the graphics card and CPU are taken and verified with different PSUs. This information is from Basic & Practice, page 6 on igor´sLAB (igorslab.de).
The machine stopped working entirely, leaving only a black display. Pressing the power button restored normal operation. I have an older 3600X available for testing, and my other PC has a 6700XT, though those are the final components still in place. The backup power supply is a 1000W unit. There aren’t many clear logs, but the only notable occurrence was "Event 41," which simply indicates an unexpected shutdown.
