3. Betjeningsvejledning
3.1. Smart Zero Fan Function
The Smart Zero Fan function ensures silent operation by preventing the 120mm FDB fan from spinning until the power supply load exceeds 20%. This minimizes undesired noise during low-load conditions. A physical switch on the back of the PSU allows you to enable or disable this function.

3.2. Tænd/sluk
After all components are securely connected, plug the AC power cord into the power supply and a wall outlet. Flip the main power switch on the PSU to the 'ON' position to power your system.
4. Vedligeholdelse
For at sikre optimal ydeevne og levetid for din strømforsyning:
- Keep the power supply and surrounding area free from dust and debris. Use compressed air to clean the fan and vents periodically.
- Ensure adequate airflow within your PC case to prevent overheating.
- Avoid operating the power supply in high humidity or extreme temperature environments.
5. Fejlfinding
If you encounter issues with your power supply, consider the following:
- Ingen strøm: Double-check all power connections, including the AC power cord, 24-pin ATX, and CPU power cables. Ensure the main power switch on the PSU is in the 'ON' position.
- Systemustabilitet: Verify that all modular cables are correctly and firmly plugged into the power supply and components. Ensure your system's power requirements do not exceed the PSU's capacity.
- Ventilatoren drejer ikke: If the Smart Zero Fan function is enabled, the fan will not spin until the PSU load exceeds 20%. This is normal operation. If the fan never spins under load, check the Smart Zero Fan switch position.
- Overophedning: Ensure proper ventilation in your PC case. Clean any dust buildup on the PSU fan and vents.
