   • Connect SATA power cables to your hard drives, SSDs, and optical drives.
   • Connect Molex power cables to any other peripherals that require them.
6. Cable Management:

   Route cables neatly behind the motherboard tray or in other designated areas of your case to improve airflow and aesthetics.

7. Final Check:

5. Operating Instructions

The Antec HCG-750 is designed for reliable and efficient operation.

• Power On: Connect the AC power cord to the power supply and then to a wall outlet. Ensure the power switch on the back of the power supply is in the 'ON' (I) position. You can then power on your computer using its front panel power button.
• Power Off: Shut down your computer through the operating system. Once the system is off, you can switch the power supply to the 'OFF' (O) position if you intend to disconnect it or perform maintenance.
• 80 PLUS BRONZE Certification: This power supply features 80 PLUS BRONZE certification, indicating high energy efficiency. This means less wasted heat and lower electricity consumption compared to non-certified power supplies.
• Continuous Power: The HCG-750 provides 750 Watts of continuous power, ensuring stable and consistent performance for your components under various loads.

6. Maintenance

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

• Cleaning: Periodically clean the exterior of the power supply and its fan grille using a soft, dry cloth. For internal cleaning, use compressed air to gently remove dust from the fan and vents. Always disconnect the power supply from the AC outlet before cleaning.
• Ventilation: Ensure that the power supply's intake and exhaust vents are not obstructed. Maintain adequate airflow within your computer case.
• Environmental Conditions: Operate the power supply within recommended temperature and humidity ranges. Avoid extreme conditions.

7. Troubleshooting

If you encounter issues with your Antec HCG-750 power supply, refer to the following common troubleshooting steps:

• 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 back of the power supply is in the 'ON' (I) position.
  • Verify that the wall outlet is functional by plugging in another device.
  • Confirm all internal power cables (24-pin ATX, EPS12V, PCI-E) are firmly seated.
• System Instability/Random Shutdowns:
  • Ensure the power supply is adequately rated for all your system components. The HCG-750 provides 750W, which is sufficient for most high-performance systems, including those with multiple GPUs.
  • Check for overheating. Ensure proper case ventilation and that the power supply fan is operating.
  • If possible, test the power supply with a different set of components or in another system to isolate the issue.
• Unusual Noises:
  • A slight fan noise is normal during operation. If you hear grinding, clicking, or excessive noise, ensure no cables are obstructing the fan.
  • If the noise persists and is abnormal, discontinue use and contact Antec support.

If these steps do not resolve the issue, please contact Antec customer support for further assistance.
