The main point: if you disconnect the fan connector and switch on
the power supply, it will record the fault status to the internal
memory and the power supply will become unusable permanently. When you switch on the power supply it will power on for 2-3 seconds and turn to stand by mode.
There was an unlucky attempt to reset the fault status via USB to I2C adapter based on CH341A chip.
There is an idea to reset the fault status via USB to PMBus adapter, but
it costs almost as a new or used power supply. Please, submit a
solution if you got one.
