As shown in fig. 1, in the computer power supply of this embodiment, a key indicator lamp 9 is further disposed on the power circuit board 2; the main control chip IC1 further comprises an indication output end; the key indicator lamp 9 is electrically connected with the indication output end.

Specifically, the input wire is used for connecting with the mains supply; the output wire is used for supplying power for the computer accessories; the power supply unit 7 is a power supply unit 7 in a common computer power supply in the market, the structure of the power supply unit is not limited, and the function of converting the commercial power into the voltage required by the computer and the power circuit board 2 can be realized. The light-emitting body 5 can be arranged on the fan blade of the fan 4 or on the bracket of the fan 4, so that when the fan 4 works, a user can visually observe the working state of the fan 4. The main control chip IC1 and the light emission control chip IC2 are all common processing chips such as a common single chip microcomputer in the market, and the structure thereof is not limited. The temperature sensor 6 is used for detecting the temperature of the current computer power supply, and preferably, can be selected as a negative temperature coefficient thermistor.

In operation, the temperature sensor 6 converts the collected temperature information into an electrical signal and sends the electrical signal to the main control chip IC1, and then the main control chip IC1 outputs different electrical signals to the fan 4 according to the received temperature information, so as to control the rotation speed of the fan 4, in order to linearly control the rotation speed of the fan 4, the main control chip IC1 converts the collected temperature information into PWM signals with different duty ratios to drive the fan 4, specifically, the PWM signal output by the main control chip IC1 is directly connected to the PWM pin of the fan 4, so as to realize the rotation speed change of the fan 4, and more preferably, the rotation speed of the fan 4 can be set to be changed between 10% and 100% of the maximum power. For example, the rotation of the fan 4 is stopped below 40 °, the rotation speed of the fan 4 is linearly changed above 40 °, and the maximum rotation speed of the fan 4 is reached at 70 °. By short pressing of the key, low-speed operation of keeping 10% below 40 degrees can be realized. When the heat generation is small, the fan is turned off.

The main control chip IC1 is convenient for a user to light or extinguish the luminous body 5 at any time by arranging the key switch 8; in practical application, when the light-emitting body 5 needs to be turned off, a user only needs to press the key switch 8 for 3 seconds, and the main control chip IC1 lights the key indicator lamp 9 after receiving a signal of the key switch 8; at this time, since the other end of the key switch 8 is electrically connected with the light-emitting control chip IC2, after the key switch 8 is pressed for 3 seconds, the second light-emitting output end of the light-emitting control chip IC2 controls the light-emitting body 5 to be turned off; similarly, when the light emitter 5 needs to be turned on, the key switch 8 is turned on only by pressing for 3 seconds, and the light emitter 5 is turned on. This is a soft control mode.

However, in the soft control method, the light emission control chip IC2 is also in a power consumption state when the light emitter 5 is turned off, and therefore, the transistor Q1 is provided to further save power. Initially, a first light emitting control end of the main control chip IC1 is set to output a high level, that is, the base voltage of the triode Q1 is a high level, the triode Q1 is turned on at this time, the light emitting control chip IC2 normally works, the power is slightly lost, and the key switch 8 normally controls the light emitting body 5 to be turned on or off; when the main control chip IC1 detects that the key switch 8 is pressed for 3 seconds and then continues to be pressed for 3 seconds, the first light-emitting control end of the main control chip IC1 outputs a low level, the triode Q1 is turned off, the working voltage of the light control chip IC2 is turned off, the IC2 is completely powered off, and the power loss is reduced.

As shown in fig. 2, in the computer power supply of the present embodiment, the heat dissipation hole 3 is hexagonal.

Through the arrangement, more heat dissipation holes 3 can be arranged in a limited area, and the supporting force of the shell 1 can be prevented from being weakened greatly.
