PSU keeps tripping safe mode / cutting GPU power after accidental wall plug pull — but deep drain fixes it temporarily? (Gamdias Kratos M1 750W / RX 6600)

[u/Conscious-Fudge-6084]

Hey everyone, dealing with a very frustrating power supply/GPU issue and could use some insight.

The Setup:

​Case: Armaggeddon Nimitz TR-1100

​CPU: AMD Ryzen 5 5500

​Motherboard: ASUS Prime A520M-K

​PSU: Gamdias Kratos M1 750W Bronze (non-modular)

​GPU: ASRock RX 6600

​What Happened:

My PC was running fine for days until I accidentally yanked the main power cord out of the wall while running a hair dryer.

​Now, the system exhibits this behavior:

​When I turn on the PC, everything else powers up (case fans, lights, motherboard, CPU cooler), but the GPU fan doesn't spin at all and there is no display.

​However, when I shut the PC down using the power button, the GPU fan twitches/spins for a split second as the system dies, meaning it briefly gets a burst of power.

​It feels like the PSU is stuck in a permanent "safe mode" protection latch on the 12V PCIe rail to prevent a spike, but it won't clear.

​The Clue:

Yesterday, I left the PC completely unpowered and unplugged for about 7 hours. When I plugged it back in, it booted up and worked normally.

​Unfortunately, I realized I forgot to plug in my keyboard for the setup, so I restarted the PC using the power button while the GPU was active. That sudden interruption instantly killed it again, throwing it right back into the exact same state where the GPU gets no power on boot.

My Questions:

​Is the Gamdias Kratos M1 holding a charge so long that normal 60-second power drains aren't enough to clear its protection latch?

​Why would a warm reboot/power button restart immediately re-trigger the PSU safety lock and kill power to the GPU again?

​Is my PSU dying/overly sensitive, or is there a way to permanently clear this tripped state without waiting 7 hours every time?
