In simple terms, the computer power supply converts alternating current (AC) into direct current (DC) to provide the necessary power for each component of the computer. It plays a vital role in the stable operation of the computer and protecting the hardware security. **Composition of Computer Power Supply** 1. Power supply shell: Protects the internal components of the power supply from external influences. 2. Circuit board: Carries the electronic components and circuits of the power supply, achieving voltage conversion and current regulation. 3. Transformer: Raises or lowers the voltage to meet the needs of different hardware devices.

4. Capacitors and inductors: Used for filtering, energy storage, and circuit protection.

5. Fan: A key component for cooling, keeping the power supply temperature within a safe range. **Main Parameters of Power Supply** 1. Power: Represents the maximum electrical energy that the power supply can provide, measured in watts (W). When selecting a power supply, the power should be slightly greater than or equal to the total power consumption of the computer hardware. 2. Interface type: Including ATX, EPS, and other interface types, which should be compatible with the motherboard and graphics card hardware. 3. Voltage and current: The output voltage and current of the power supply should match the hardware requirements to avoid damaging the hardware. 4. 80PLUS certification: Indicates that the power supply's conversion efficiency and performance meet certain standards, an important indicator of power supply quality. **How to Choose a Suitable Computer Power Supply** 1. Select a power supply with an appropriate power rating based on the computer configuration, with some margin for spare power. 2. Pay attention to whether the interface type is compatible with the motherboard and graphics card hardware. 3. Choose a power supply brand with good quality assurance and after-sales service. 4. Refer to other user reviews and usage experiences to select a cost-effective power supply. **Notes for Using and Maintaining Computer Power Supply** 1. Ensure good ventilation of the computer power supply to avoid overheating. 2. Regularly clean the dust inside the power supply to maintain good cooling efficiency. 3. Avoid frequent switching on and off to extend the service life of the power supply. 4. If a problem with the power supply is detected, replace it promptly to avoid damaging other hardware components.
