4. Setup and Installation

Follow these steps to properly install your Aerocool KCAS 750GM RGB Power Supply into your PC case.

1. Mounting the Power Supply: Secure the power supply into the designated PSU bay of your PC case using the provided mounting screws. Ensure the fan is facing the correct direction for optimal airflow (usually facing downwards if your case has a bottom vent, or upwards if it's a top-mounted PSU).
2. Connecting Main Power Cables:
   • Connect the 24-pin ATX motherboard power cable to your motherboard's main power connector.
   • Connect the 8-pin (4+4 pin) CPU power cable to your motherboard's CPU power connector.
3. Connecting Modular Cables: Identify the necessary modular cables for your components (graphics card, SSDs/HDDs, etc.) and connect them to the corresponding ports on the power supply and your components.

   • PCI-Express (PCI-E) Cables: Use these for graphics cards. The KCAS 750GM provides multiple PCI-E connectors to support high-end GPUs.
   • SATA Cables: For SSDs, HDDs, and optical drives.
   • Peripheral/Molex Cables: For older components or fan controllers.
4. RGB Connection (Optional): If you wish to control the RGB lighting via a compatible motherboard or controller (like Aerocool P7-S1 or P7-Hub), connect the appropriate RGB sync cable from the power supply to your motherboard's RGB header or the controller.
5. Connect AC Power Cord: Once all internal connections are secure, connect the AC power cord to the power supply's inlet and then to a wall outlet or surge protector.
6. Power Switch: Ensure the power switch on the back of the PSU is in the "OFF" (0) position before connecting to AC power. After connecting, you can switch it to "ON" (I) to power your system.

• Fan Operation: The 12cm silent fan operates with an intelligent thermal fan speed control circuit. This means the fan speed adjusts automatically based on the power supply's temperature, ensuring efficient cooling while minimizing noise.

6. Maintenance

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

• Dust Removal: Periodically clean dust from the power supply's fan and ventilation grilles using compressed air. Ensure the power supply is turned off and unplugged before cleaning.
• Ventilation: Ensure that the PC case has adequate airflow and that the power supply's intake and exhaust vents are not obstructed.
• Do not attempt to open the power supply casing for cleaning or any other purpose.

7. Troubleshooting

If you encounter issues with your Aerocool KCAS 750GM RGB Power Supply, refer to the following common troubleshooting steps:

• No Power to System:
  • Check if the AC power cord is securely connected to both the power supply and the wall outlet.
  • Ensure the power supply's main switch on the back is in the "ON" (I) position.
  • Verify that the 24-pin ATX and 8-pin CPU power cables are firmly seated in their respective motherboard connectors.
  • Test the wall outlet with another device to ensure it has power.
• System Instability or Random Shutdowns:
  • Ensure all modular cables are correctly and securely connected to both the power supply and the components.
  • Check for proper ventilation within your PC case. Overheating can cause instability.
  • Verify that your system's power requirements do not exceed the 750W capacity of the power supply.
• RGB Lighting Not Working:
  • Ensure the RGB sync cable is properly connected to your motherboard's RGB header or an Aerocool P7-Hub/P7-S1.
  • Check your motherboard's or Aerocool's RGB software settings to ensure lighting is enabled and configured correctly.

If issues persist after following these steps, please contact Aerocool customer support or your retailer for further assistance.
