4.2 Physical Installation

  1. Prepare Your System: Ensure your computer is completely powered off and unplugged from the wall outlet.
  2. Remove Old PSU (if applicable): Disconnect all cables from your old power supply and remove it from the chassis.
  3. Mount the New PSU: Carefully place the Redragon RGMS-1200W PRO into the power supply bay of your computer case. Secure it with the provided mounting screws.
  4. Connect Main Power Cables:
    • Connect the 24-pin ATX cable to your motherboard.
    • Connect the 8-pin (4+4) ATX 12V CPU power cable(s) to your motherboard.
  5. Connect GPU Power Cables:
    • For modern GPUs requiring PCIe 5.1, connect the 12VHPWR cable directly to your graphics card.
    • For other GPUs, use the appropriate 8-pin (6+2) PCIe cables.

    IMPORTANT: When bending the 12VHPWR cable, ensure a minimum distance of 35mm from the connector before bending to prevent damage. Do not bend horizontally or over-bend the cable.

  6. Connect Peripheral Cables: Connect SATA power cables to your storage drives (HDDs, SSDs) and optical drives. Use Molex cables for other peripherals if needed.
  7. Cable Management: Utilize the fully modular design and flat cables to route and secure cables neatly within your chassis for optimal airflow.
  8. Final Check: Double-check all connections to ensure they are secure and correctly seated.

5. Operation

5.1 Powering On

  1. After completing the installation and verifying all connections, connect the AC power cord to the power supply and then to a wall outlet.
  2. Flip the power switch on the back of the PSU to the "ON" position (usually marked with "I").
  3. Power on your computer.

5.2 Zero RPM Fan Mode

The Redragon RGMS-1200W PRO features a Zero RPM fan mode. The fan will remain off under low loads to provide silent operation. It will automatically activate when the internal temperature of the PSU reaches approximately 60°C to ensure optimal cooling. This is normal operation and not an indication of a fault.

5.3 RGB Lighting Control (if applicable)

Some models may include RGB lighting. If present, a button on the back of the PSU allows you to cycle through various lighting effects. To turn off the LED lighting, press and hold the RGB button for a few seconds.

6. Maintenance

To ensure the longevity and optimal performance of your power supply, follow these maintenance guidelines:

  • Cleaning: Periodically clean the exterior of the power supply and its fan grille to prevent dust buildup. Use compressed air to gently clear dust from the fan and vents. Ensure the PSU is unplugged before cleaning.
  • Environment: Operate the power supply in a clean, dry, and well-ventilated environment.
  • Cable Integrity: Regularly check that all modular cables are securely connected and free from damage.

7. Troubleshooting

ProblemPossible CauseSolution
