6. Operating Instructions
The LIAN LI SP850 is designed for reliable and efficient operation. Once installed and connected, the power supply will provide stable power to your system. The fan operates intelligently, only spinning up when a certain core temperature is reached, ensuring quiet operation under light loads.
7. Maintenance
- Regularly check for dust accumulation on the fan and ventilation grilles. Use compressed air to gently clean dust from the unit.
- Ensure all cables are securely connected and free from damage.
- Avoid placing objects on top of the power supply or obstructing its airflow.
8. Troubleshooting
- No Power: Check if the AC power cord is securely connected to both the power supply and the wall outlet. Ensure the power switch on the PSU is in the 'ON' position. Verify all modular cables are correctly seated.
- Fan Not Spinning: The fan is designed to remain off under low load conditions until the internal temperature reaches 60°C. This is normal operation and not a fault. If the system is under heavy load and the fan is still not spinning, check for obstructions or contact support.
- System Instability: Ensure all power connections to your components (motherboard, CPU, GPU) are correct and secure. If issues persist, consult the motherboard and component manuals or contact support.
