Abstract: The invention provides a power supply including at least one power output port, at least one status alert component, and at least one output port status monitoring module. The status alert component generates at least one visual prompt based on an alert signal. The output port status monitoring module includes at least one temperature sensor adjacent to the power output port, a microcontroller connected to the temperature sensor and sensing an output current from the power output port, and a reset signal generator connected to the microcontroller. The microcontroller comprises at least one port status alert condition that takes a temperature and the output current of the power output port as decision factors. The microcontroller outputs the alert signal to the status alert component when the port status alert condition is met and maintains the status until a reset signal provided by the reset signal generator is received.

Abstract: The present invention provides a fan speed control method for avoiding inaccurate control caused by sudden changes in a power supply output state, including the steps of: acquiring an output current value of a power supply device; and then, determining a change of the output current value in a sampling timeframe, if a slope representing the change is positive, controlling the control signal generating unit to gradually replace the fan control signal currently output to the fan with another fan control signal on the basis of a first latency, and if the slope representing the change is negative, controlling the control signal generating unit to gradually replace the fan control signal currently output to the fan with another fan control signal on the basis of a second latency. The first latency and the second latency are determined by the output current value, respectively.
