4. Operating Instructions
4.1 Powering On/Off
Ensure all components are correctly connected before powering on your system. Use the main power switch on the PSU to turn the unit on or off. Always power down your system and unplug the PSU from the wall outlet before performing any internal hardware changes or maintenance.
4.2 Fan Operation
The PSU features a 120mm PWM fan designed for optimal cooling and low noise. It operates in a fanless mode during low loads for quiet operation, and the fan speed adjusts automatically based on power output to maintain optimal temperatures.

5. Maintenance
5.1 Magnetic Dust Filter Cleaning
The magnetic mesh dust filter on top of the fan can be easily removed for regular cleaning. This ensures dust-free operation, maintains ample ventilation, and extends the PSU's lifespan and reliability.
- Gently pull the magnetic dust filter upwards to remove it from the PSU.
- Clean the filter using a soft brush or compressed air to remove accumulated dust.
- Align the filter with the PSU's top panel and allow the magnets to secure it back in place.

7. Troubleshooting
If you encounter issues with your Lian Li EDGE1200W Power Supply, consider the following troubleshooting steps:
- No Power: Ensure the PSU's main power switch is in the 'ON' position and the power cable is securely connected to both the PSU and a working wall outlet. Verify that the motherboard's 24-pin and CPU power connectors are firmly seated.
- System Instability/Crashes: Check all power connections to components (GPU, storage drives, etc.) to ensure they are secure. If issues persist, test components individually if possible, or consult a qualified technician.
- Fan Noise: The PSU fan operates in a fanless mode at low loads. If the fan is constantly running loudly, ensure adequate airflow within your PC case and that the PSU's dust filter is clean.
- USB/Fan Hub Issues: Verify the hub is correctly connected to the PSU or independently powered. Check motherboard signal connections (USB Type-A or USB-USB) for proper data transfer.
