5. Operating Instructions

5.1. Smart Cooling Feature

The SP1000P features a smart cooling system with a zero-RPM mode. The fan remains off for silent operation when the power load is at or below 40%. As the system load increases above 40%, the fan will gradually ramp up to maintain optimal temperatures and ensure long-term reliability.

5.2. Powering On/Off

After all connections are made and secured, ensure the main power switch on the PSU (or the in-line switch if used) is in the 'ON' position. Then, power on your computer system as usual.

6. Maintenance

To ensure the longevity and optimal performance of your power supply, follow these maintenance guidelines:

• Dust Removal: Periodically clean the exterior of the power supply and the fan grille to prevent dust buildup, which can impede airflow and lead to overheating. Use compressed air or a soft brush.
• Cable Inspection: Regularly check all modular cable connections to ensure they remain secure and free from damage.
• Environment: Operate the power supply in a clean, dry, and well-ventilated environment. Avoid extreme temperatures and humidity.

7. Troubleshooting

If you encounter issues with your power supply, refer to the following common troubleshooting steps:

• No Power:
  • Ensure the main power cable is securely connected to both the PSU and the wall outlet.
  • Verify that the power switch on the PSU (and the in-line switch if used) is in the 'ON' position.
  • Check all modular cable connections, especially the 24-pin ATX and CPU power cables, to ensure they are fully seated.
• System Instability/Crashes:
  • Ensure the 12V-2x6 connector for your GPU is fully inserted, as indicated by the disappearance of the blue colored part.
  • Confirm that your system's power requirements do not exceed the PSU's 1000W capacity.
• Unusual Noise (e.g., Coil Whine):
  • While some electronic components can exhibit minor coil whine under certain loads, persistent or loud noise may indicate an issue. Ensure the PSU is properly mounted and not vibrating against the case.
  • If the noise is excessive or concerning, contact Lian Li support.

If problems persist after following these steps, please contact Lian Li customer support for further assistance.
