英文翻译： Computer Power Supply Knowledge Introduction: Understanding the "Heart" of Your Computer Among the numerous components of a computer, the power supply is often regarded as the "heart" of the computer, providing power for the entire system. It is not only a simple power supply device, but also a key factor in ensuring the stable operation of the computer. Below, we will explore the related knowledge of computer power supply in depth. Firstly, the basic concept of computer power supply. The computer power supply, also known as a power supply unit or power supply, mainly converts alternating current (AC) into direct current (DC), providing a stable power supply for various parts of the computer. The quality of the power supply directly affects the performance and stability of the computer. Secondly, the composition of the computer power supply. The fan inside the power supply is responsible for cooling and ensuring that the power supply can work normally in high-temperature environments. The circuit board is the core part of the power supply, with electronic components and circuits laid out on it. The transformer lowers or increases the input voltage to meet the needs of various computer parts. The filtering capacitor is used to filter out noise in the power supply and ensure the stability of the output voltage. Thirdly, how to choose a high-quality computer power supply. Consider the power requirements based on the configuration of your computer to select an appropriate power supply that can meet the needs of each part. Choose a well-known brand and a high-quality power supply to avoid computer malfunctions caused by inferior power supplies. Ensure that the power supply has relevant safety certifications, such as 80PLUS certification. The fan design of the power supply should be reasonable to reduce noise and ensure a good working environment. Finally, usage and maintenance of computer power supply. Pay attention to the use environment, avoiding placing the computer in damp, high-temperature, or dusty environments to prolong the service life of the power supply. Regularly clean the dust inside the power supply to ensure good cooling effect. Prevent overloading by not running your computer in excessive load conditions, so as not to burden the power supply excessively. Replace it timely if any fault or aging occurs to ensure normal use of your computer.
