1. 电源供电不足：更换功率更高的电源或检查硬件配置是否超过电源的承载能力。 2. 电源噪音大：可能是电源风扇的问题，可考虑更换风扇或清洁风扇。 3. 电源短路：检查电源线是否损坏或接触不良，及时更换或修复。 七、英文翻译： 1. Computer Power Supply: It is a power device that converts alternating current (AC) to direct current (DC) to provide a stable power supply for computer hardware. 2. Components of Computer Power Supply: Input port, rectifier, transformer, filter, and output port. 3. Power of Computer Power Supply: It is measured in watts (W), indicating the maximum power that the power supply can provide. When selecting a power supply, ensure that its power is sufficient to supply all the hardware of the computer. 4. Interfaces of Computer Power Supply: It provides power for computer hardware through various interfaces, such as ATX interfaces with 20 or 24 pins, PCI-E interfaces, etc. 5. How to choose a suitable computer power supply? Consider the power of the power supply to ensure that it can supply all the hardware of the computer; pay attention to the interface types of the power supply to ensure that they match the interfaces of the computer hardware; choose a brand and a product with reliable quality to ensure the stability and safety of the power supply; pay attention to the efficiency and cooling performance of the power supply to reduce energy consumption and temperature. 6. Common problems and solutions of computer power supply: insufficient power supply, replace a higher-powered supply or check if the hardware configuration exceeds the carrying capacity of the power supply; loud noise from the power supply, which may be a problem with the power supply fan, consider replacing or cleaning the fan; short circuit of the power supply, check if the power cord is damaged or poorly connected, and timely replacement or repair. 通过以上内容，我们对电脑电源的基础知识有了从A到Z的全面了解，希望能对你有所帮助。
