3. セットアップ手順
Follow these steps to properly install your FormulaMod 12VHPWR Extension Cable:
- システムを準備します: 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.
- コネクタを識別します。 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.
- GPUに接続します: 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.
- PSUに接続します: Connect each of the four 8-pin female connectors from the extension cable to four 独立した 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. 操作手順
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. メンテナンス
The FormulaMod 12VHPWR Extension Cable requires minimal maintenance. Follow these guidelines to ensure its longevity and optimal performance:
- 定期点検: Periodically check the cable and its connectors for any signs of wear, damage, or discoloration.
- 清潔さ: Keep the cable free from dust and debris. Use compressed air or a soft, dry cloth to gently clean the cable and connectors.
- ストレスを避ける: 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.
- 安全な接続: Ensure all connections remain firmly seated. Loose connections can lead to power instability or component damage.

6。 トラブルシューティング
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.
- システムの不安定性またはクラッシュ:
- 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.
- 物理的ダメージ: If the cable appears damaged, bent, or discolored, discontinue use immediately and replace it.
