- Evitar o estrés: 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.
- Conexións seguras: Ensure all connections remain firmly seated. Loose connections can lead to power instability or component damage.

6 Solución de problemas
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.
- Inestabilidade ou fallos do sistema:
- 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.
- Danos físicos: If the cable appears damaged, bent, or discolored, discontinue use immediately and replace it.
