5. Operating Instructions

5.1 Powering On/Off

Connect the AC power cord to the power supply and a wall outlet. If using the included internal power switch cable, ensure the switch is in the "ON" position before connecting or disconnecting the main power cable.

5.2 Smart Cooling Feature

The power supply features a smart cooling system with a fanless mode. The fan remains off for silent operation when the system load is at or below 40%. As performance demands increase and the load exceeds 40%, the fan will automatically engage and ramp up to maintain optimal temperatures and ensure long-term reliability.

8. Maintenance

  • Keep the power supply and surrounding area free from dust. Use compressed air to gently clean the fan and vents periodically.
  • Ensure adequate airflow around the power supply within the PC case.
  • Avoid placing objects on top of the power supply or blocking its ventilation.

9. Troubleshooting

  • No Power: Check all power connections, including the AC power cord, the internal power switch cable (if used), and the 24-pin ATX connector to the motherboard. Ensure the wall outlet is functional.
  • System Instability/Crashes: Verify all modular cables are securely connected to both the power supply and the components. Ensure your system's power requirements do not exceed the PSU's capacity.
  • Fan Not Spinning: The power supply features a fanless mode below 40% load. If the system load is low, the fan may not spin. If the system is under heavy load and the fan is still not spinning, ensure there are no obstructions and contact support if the issue persists.
  • Overheating: Ensure proper case ventilation and that the power supply's fan and vents are not obstructed by dust or other components.
