A high-performance power cable not only provides sufficient power supply but also guarantees the stability and safety of hardware equipment. I. Basic Function of Power Cables Power cables are the bridge connecting the computer mainframe and the power supply. Their main function is to provide a continuous and stable power supply for the computer. Specifically, their main tasks include: 1. Power transmission: The main responsibility of the power cable is to transmit power from the power supply to the computer mainframe. This requires the power cable to have good electrical conductivity and load capacity.

2. Voltage stabilization: Power cables should have the ability to adjust voltage, ensuring stable voltage under different working loads for the normal operation of hardware equipment.

3. Current distribution: Power cables should be able to distribute current reasonably to meet the needs of various parts of the computer, avoiding equipment damage caused by excessive or insufficient current. II. Essential Elements for Ensuring Stable Computer Operation 1. High-quality power cables: Selecting high-quality, compliant power cables is the foundation for ensuring stable computer operation. Good power cables have excellent electrical conductivity, load capacity, and anti-interference ability. 2. Correct connection method: When installing power cables, follow the correct connection method to ensure that the power cable is securely connected to the computer mainframe and power supply with good contact.

3. Regular inspection and maintenance: Regularly inspecting and maintaining power cables can及时发现and solve potential problems and prevent computer failures caused by aging, damage, or other reasons of the power cable.

4. Lightning and surge protection: Quality power cables should have lightning and surge protection functions to protect the computer from external factors such as lightning and surges. 综上所述，了解并正确使用电源线对于确保电脑的稳定运行至关重要。我们应该选择高品质的电源线，并采取正确的连接和维护措施，以保障电脑的稳定运行和安全性。
