3. Setup Instructions

Follow these steps to properly install your FormulaMod 12VHPWR Extension Cable:

1. Prepare your System: Ensure your computer is powered off and unplugged from the wall outlet. Open your computer case to access the graphics card and power supply unit.
2. Identify Connectors: Locate the 16-pin (12+4) power input on your PCIe 5.0 graphics card. Identify four available 8-pin PCIe power output connectors on your power supply unit.
3. Connect to GPU: Carefully insert the 16-pin male connector of the extension cable into the corresponding 16-pin port on your graphics card. Ensure it is fully seated and latched.
4. Connect to PSU: Connect each of the four 8-pin female connectors from the extension cable to four independent 8-pin PCIe power cables from your power supply. It is crucial to use separate cables from the PSU for each 8-pin connector on the extension cable to ensure stable power delivery and prevent overloading.

4. Operating Instructions

Once the FormulaMod 12VHPWR Extension Cable is securely connected to both your graphics card and power supply, no further operational steps are required for the cable itself. The cable acts as a passive conduit for power. Ensure all connections are firm before powering on your system.

After installation, close your computer case, plug in the power cord, and power on your system. Verify that your graphics card receives power and functions correctly.

5. Maintenance

The FormulaMod 12VHPWR Extension Cable requires minimal maintenance. Follow these guidelines to ensure its longevity and optimal performance:

• Regular Inspection: Periodically check the cable and its connectors for any signs of wear, damage, or discoloration.
• Cleanliness: Keep the cable free from dust and debris. Use compressed air or a soft, dry cloth to gently clean the cable and connectors.
• Avoid Stress: Do not bend the cable sharply or apply excessive force to the connectors. The cable features a pre-bent design for easier routing, but extreme angles can damage the internal wiring.
• Secure Connections: Ensure all connections remain firmly seated. Loose connections can lead to power instability or component damage.

6. Troubleshooting

If you encounter issues after installing the FormulaMod 12VHPWR Extension Cable, consider the following troubleshooting steps:

• No Power to GPU:
  • Ensure the 16-pin connector is fully seated into the graphics card. A click should be heard or felt.
  • Verify that all four 8-pin connectors are securely plugged into independent PCIe power cables from your PSU.
  • Check that your PSU is adequately powered and functioning correctly.
• System Instability or Crashes:
  • Confirm that your power supply unit meets the minimum wattage requirements for your graphics card and entire system.
  • Re-check all cable connections to ensure they are firm and not loose.
  • Ensure you are using four separate 8-pin PCIe cables from the PSU, not split cables, as shown in the setup diagram.
• Physical Damage: If the cable appears damaged, bent, or discolored, discontinue use immediately and replace it.
