    I agree that faster is better, but there is definitely a 100 mS minimum time delay specified for the Power_OK signal in the ATX12V Power Supply Design Guide, Page 19, Table 12. i.e. "100mS<T3<500mS".

    I sometimes wondered how many engineers were stupid enough to actually use the minimum time for power-ups monitoring, they normally are for power-downs/ power-offs.

    It is the maximum longest time invalid states are allowed upon power-downs.
