**How to Choose the Right Power Supply Based on Needs?** To choose the right computer power supply, you need to consider actual needs and application scenarios. Here are some suggestions: 1. **Consider Power Requirements**: Select a power supply with an appropriate power rating based on the configuration and hardware requirements of the computer. Generally, the power requirement of the computer should be slightly higher than the total power requirement of the hardware to ensure stable power supply. 2. **Consider Power Supply Efficiency**: A power supply with high conversion efficiency can reduce energy waste, lower heat generation, and contribute to the stable operation of the computer. 3. **Consider Brand and Quality**: Choose a well-known brand and quality power supply to ensure stability and safety. Avoid selecting inferior or unbranded power supplies that may cause damage to computer hardware. 4. **Consider Chassis and Cooling**: If there is limited space in the chassis or good cooling performance is required, a small size and good heat dissipation power supply can be selected. 5. **Special Needs Consideration**: If the computer is used in special environments (such as industrial control, medical equipment), custom power supplies with high safety and stability should be selected.
