Computer Power Supply Detailed Explanation: From Basic to Advanced Levels 1. Basic Overview The computer power supply, also known as Power Supply Unit (PSU), is a crucial component in a computer. Its main function is to provide a stable power supply for various parts of the computer, ensuring its normal operation. 2. Basic Structure The computer power supply is mainly composed of the following parts: Input end: the interface for connecting to the commercial power supply, including live wire (L), neutral wire (N), and ground wire (G). Transformer: converts the commercial power supply into a voltage suitable for the computer parts. Rectifier: converts the alternating current (AC) into direct current (DC). Filter: filters the DC to remove noise and harmonics. Output end: the interface for providing power supply to the computer parts. 3. Power Supply Power and Selection Power supply's power is an important indicator to measure its performance. Generally speaking, the higher the power of the power supply, the more stable power supply it can provide. However, when selecting a power supply, you should choose the appropriate power according to the configuration and needs of the computer. At the same time, you should also pay attention to aspects such as the conversion efficiency and safety performance of the power supply. 4. Advanced Explanation In addition to the basic structure and power, advanced power supplies also have the following features: 80 PLUS certification: indicating that the power supply's conversion efficiency meets certain standards and can save energy. Full-modular design: it is convenient for users to customize the cables according to needs, improving installation efficiency. Silent design: it adopts silent fans or liquid cooling technology to reduce noise. Protection function: equipped with multiple protection functions such as overvoltage, overcurrent, and short circuit to ensure safe operation of the computer. Digital management: it connects to the computer system through an interface to monitor the power supply status and voltage, current, and other parameters of each component in real-time. The above is a detailed explanation of computer power supply from basic to advanced levels. Hope it can help you better understand this important component of your computer system.
