• Fan Operation: The internal fan's speed is automatically regulated by a thermal sensor to maintain optimal operating temperature and minimize noise.
• Voltage Selection: The 115/230V switch should only be adjusted when the power supply is completely disconnected from the wall outlet. Do not attempt to change this setting while the unit is powered.

7. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your power supply.

• Dust Removal: Periodically clean dust from the power supply's fan and vents using compressed air. Ensure the computer is powered off and unplugged before cleaning.
• Cable Inspection: Occasionally check all connected cables to ensure they are securely seated and free from damage.
• Ventilation: Ensure that the computer case has adequate airflow and that the power supply's vents are not obstructed.

8. Troubleshooting

If you encounter issues with your power supply, refer to the following common problems and solutions:

No Power to System:

Check if the power cable is securely connected to both the power supply and the wall outlet. Ensure the power supply's main switch (if present) is in the 'ON' position. Verify the 115/230V voltage selector switch is set correctly for your region. Confirm all internal power connectors (motherboard, CPU, etc.) are firmly seated. Test the wall outlet with another device to ensure it has power.

System Powers On but Shuts Down Immediately:

This could indicate an overload or a short circuit. Disconnect non-essential components and try again. Ensure all components are correctly installed and no metal parts are touching the motherboard or other components causing a short. Verify the power supply wattage is sufficient for all your components.

Loud Fan Noise:

While the fan speed is thermally controlled, excessive noise might indicate dust buildup. Clean the fan and vents as described in the Maintenance section. Ensure the power supply is not operating in an excessively hot environment.

If problems persist after attempting these solutions, contact customer support.
