Introduction With the widespread use of computers, the safety of computer power supplies as the energy providers of computers has become increasingly important. Correct usage and maintenance of computer power supplies can effectively extend the lifespan of computers and prevent dangerous situations such as electrical fires. Here are some guidelines for safe use of computer power supplies.

II. Pre-use Checks

Before using or replacing a computer power supply, perform the following checks: 1. Inspect the power cord for any damage, such as exposed wires or broken plugs. 2. Confirm that the output voltage and current of the power adapter match the requirements of the computer. 3. Ensure that there are no obstructions in the ventilation slots of the power supply to allow for proper cooling. III. Usage Precautions 1. Avoid using computer power supplies in damp environments to prevent electric shocks. 2. Do not place heavy objects on the computer power supply to avoid deformation or damage.

3. Avoid frequently plugging and unplugging the power cord to prevent damage or poor contact.

4. When using a computer, ensure good contact between the power plug and socket to avoid electrical sparks due to poor contact. 5. Do not unplug the power cord while the computer is still running. First, turn off the computer, then unplug the power cord. IV. Maintenance and Care 1. Regularly clean the dust inside the power supply to maintain good ventilation and cooling. 2. Avoid continuous long-term use of computer power supplies and allow the computer to rest periodically to extend the lifespan of the power supply. 3. If you notice that the power supply is overheating, has an odor, or makes excessive noise, stop using it immediately and contact a professional for inspection and repair.
