   • Connect the 4+4-pin or 8-pin EPS/CPU power cable to your motherboard.
5. Connect Modular Cables: Attach the necessary modular cables for your components (e.g., PCI-E for graphics cards, SATA for hard drives/SSDs, Peripheral for fans/accessories). Connect them securely to both the power supply and the respective components.
6. Cable Management: Route cables neatly to improve airflow and aesthetics.
7. Close Case and Power On: Close your computer case. Connect the AC power cord to the power supply and then to a wall outlet. Flip the power switch on the PSU to the 'ON' position. Power on your computer.

6. Operating Instructions

Once installed, the Antec HCG-850M operates automatically. Here are some general operating guidelines:

• Power On/Off: Use your computer's power button to turn the system on or off. The switch on the power supply itself should generally remain in the 'ON' position during normal operation.
• System Stability: Ensure your system is stable. If you experience unexpected shutdowns or reboots, refer to the troubleshooting section.
• Ventilation: Maintain good airflow around your computer case to prevent overheating of components, including the power supply.

7. Maintenance

Proper maintenance can extend the lifespan of your power supply:

• Dust Cleaning: Periodically clean dust from the power supply's fan grille and the interior of your computer case using compressed air. Always disconnect the AC power cord before cleaning.
• Cable Check: Occasionally check that all power cables are securely connected to the power supply and components.
• Environment: Operate the power supply in a clean, dry environment with stable temperatures.

8. Troubleshooting

If you encounter issues with your power supply, try the following steps:

8.1 No Power to System

• Ensure the AC power cord is securely plugged into both the wall outlet and the power supply.
• Check that the power supply's ON/OFF switch is in the 'ON' position.
• Verify all internal power cables (24-pin ATX, CPU, PCI-E) are correctly and firmly connected.
• Test the wall outlet with another device to ensure it has power.
• If possible, test the power supply in another known working system or with a PSU tester.

8.2 System Instability or Random Shutdowns

• Ensure your system's power requirements do not exceed the 850W capacity of the PSU.
• Check for overheating components. Ensure proper case ventilation and clean any dust buildup.
• Verify all power connections are secure. Loose connections can cause intermittent power delivery.
• If the issue persists, it may indicate a fault with the power supply or another component. Consider professional diagnosis.
