5.2 Connecting Cables

Connect the appropriate cables to your motherboard and components. Refer to your motherboard and component manuals for specific connection points.

1. Motherboard Power: Connect the 24-pin ATX connector to the corresponding socket on your motherboard.
2. CPU Power: Connect the 4+4-pin EPS/ATX 12V connector to the CPU power socket on your motherboard.
3. Graphics Card Power: If your graphics card requires external power, connect the 6+2-pin PCI-E connector(s) to the graphics card.
4. Storage Devices: Connect SATA power connectors to your SATA hard drives, SSDs, and optical drives.
5. Peripherals: Use Molex 4-pin connectors for case fans or other legacy peripherals as needed.
6. Cable Management: Route cables neatly to ensure proper airflow within the case.

Once all internal connections are made, close your computer case.

5.3 External Connection

1. Connect the AC power cord to the power supply's AC inlet.
2. Plug the other end of the AC power cord into a grounded wall outlet or surge protector.
3. Ensure the power switch on the back of the power supply is in the "OFF" (O) position before plugging it in.

6. Operating Instructions

6.1 Powering On Your System

1. After all connections are secure, flip the power switch on the back of the power supply to the "ON" (I) position.
2. Press the power button on your computer case to start the system.

6.2 Thermal Control System

The FSP400-60GHS(85)-R1 features an 80mm cooling fan with thermal sensing technology. This system automatically adjusts the fan speed based on the internal temperature of the power supply, optimizing cooling performance while minimizing noise.

6.3 Energy Saver Standby Mode

This power supply is designed with an energy-saving 1-watt standby mode, reducing power consumption when the system is in a low-power state or turned off but still connected to AC power.

7. Maintenance

Proper maintenance ensures the longevity and optimal performance of your power supply.

• Cleaning: Periodically clean the exterior of the power supply and its fan grille to prevent dust buildup. Use a soft, dry cloth or compressed air. Ensure the power supply is disconnected from AC power before cleaning.
• Ventilation: Ensure that the power supply's fan and ventilation openings are not obstructed. Good airflow is crucial for cooling.
• Cable Integrity: Regularly check all power cables for any signs of wear, fraying, or damage. Replace damaged cables immediately.

Do not attempt to open the power supply unit for internal cleaning or repair. This will void the warranty and can be dangerous.

8. Troubleshooting

If you encounter issues with your power supply, refer to the following common problems and solutions:

8.1 No Power to System

• Check AC Power: Ensure the AC power cord is securely plugged into both the power supply and a working wall outlet.
• Power Switch: Verify that the power switch on the back of the power supply is in the "ON" (I) position.
• Internal Connections: Confirm that the 24-pin ATX and 4+4-pin EPS/ATX 12V connectors are firmly seated in the motherboard.
• Short Circuit: Disconnect all peripheral power cables (SATA, Molex, PCI-E) and attempt to power on. If the system powers on, a short circuit may exist in one of the connected components or cables. Reconnect them one by one to identify the faulty component.

8.2 System Instability or Random Shutdowns

• Overload: Ensure your system's power requirements do not exceed the 400W capacity of the power supply.
• Ventilation: Check for proper airflow within the case and ensure the power supply's fan is not obstructed. Overheating can cause instability.
• Cable Connections: Re-check all power connections to ensure they are secure. Loose connections can lead to intermittent power delivery.

8.3 Excessive Fan Noise

• Dust Buildup: Clean the fan grille and fan blades with compressed air.
• Obstruction: Ensure no cables or foreign objects are interfering with the fan's rotation.
• Operating Environment: High ambient temperatures can cause the thermal control system to increase fan speed. Ensure adequate room ventilation.

If troubleshooting steps do not resolve the issue, contact FSP customer support or your retailer for assistance.
