Device shuts down and remains off until the power supply is cycled again.
You're experiencing sudden shutdowns while playing games that rely heavily on GPU power. The PC shuts down abruptly, requiring you to wait about five seconds before powering it back on. This issue occurs with several titles including Subnautica, Satisfactory, Borderlands 3, and Elden Ring. There are no error messages or blue screens—just a complete loss of power. Your system specs show a powerful setup, but the wattage estimate is around 423W. It seems the problem might be related to power delivery under load. Have you tried testing the power supply with a different unit or checking for loose connections? Also, consider monitoring real-time power draw with tools like HWMonitor or Core Temp to see if spikes happen during gameplay.
It seems like this could be a brief situation. Examine your motherboard for any metal-to-metal connections. Also, inspect beneath or behind it. If you attached any of the metal anchors from your case in spots where the board doesn’t have space, that might be the issue. I dropped a screw and it got stuck under my VRM heatsinks. I searched everywhere but couldn’t locate it. Despite that, the system booted normally, games loaded fine, but after roughly 30 seconds into play it would crash. I had to take apart the whole machine to find the tiny screw.
definitely psu, symptom you often describe with worn, swollen, or blown caps in psu. If other parts fail, they rarely shut down completely like that, causing crashes and sounds. You're lucky the psu is turning itself off to avoid harming other components. Don't risk it—replace another psu and try again.
All the extra screws are accounted for. It doesn’t look like anything is touching the case. I’m not sure how to verify this. I have my old PSU from before upgrading the CPU and GPU, but it’s only 550W—uncertain if it could cause issues with the new setup.
Could the system be getting too hot? This has been occurring after installing the new PSU; my previous unit never experienced this problem. The old model had an air intake inside the case, whereas the new one directs airflow from the bottom of the case. My computer doesn’t shut down right away during intense gaming sessions—it slows down for a moment before powering off, suggesting overheating might be the cause.
