Abstract: The invention provides a power supply structure of a desktop computer, a mainboard to which the desktop computer belongs comprises a mainboard power input port. The power supply structure comprises a cabinet, a power supply device, a power adapting device and a mainboard power supply line. The cabinet comprises a cabinet inner space and a bearing plate. The cabinet inner space is divided into a mainboard mounting side provided for the mainboard to be disposed thereon and a back side. The bearing plate comprises a first through hole. The power adapting device is disposed in the cabinet and located at the back side. The power adapting device comprises a power source input port and a mainboard power supply port penetrating through the first through hole. The mainboard power supply line is connected with the mainboard power supply port and the mainboard power input port.

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: A fan driving circuit with temperature compensation comprises a power input end, a power output end connected with a fan motor, a first transistor arranged between the power input end and the power output end, a signal adjuster connected with the first transistor and connected with a signal generating circuit, a second transistor connected with the signal adjuster, and a feedback unit. The feedback unit comprises a first resistor and a second resistor connected in series, and a compensation bypass connected in parallel with the first resistor or the second resistor, wherein the compensation bypass comprises a thermistor, a resistance of the thermistor changes along with the temperature and changes a magnitude of a feedback current which is provided to the second transistor, so as to compensate a change of a common emitter current gain in the second transistor generated by the temperature.
