4. Configuración e instalación
Follow these steps to install your COUGAR GX-S 750W Power Supply:
- Preparación: Asegúrate de que o teu ordenador estea completamente apagado e desconectado da toma de corrente. Abre a carcasa do teu ordenador para acceder á zona de montaxe da fonte de alimentación.
- Montaxe da fonte de alimentación: Carefully place the GX-S 750W PSU into the designated PSU bay in your PC case. Align the screw holes on the PSU with those on the case. Secure the PSU using the provided mounting screws. Ensure the PSU fan is oriented correctly for optimal airflow (typically facing downwards if there's a vent, or upwards if not).
- Connecting Motherboard Power: Connect the 24-pin ATX power cable from the PSU to the corresponding 24-pin connector on your motherboard. Ensure it clicks securely into place.
- Conexión da alimentación da CPU: Connect the 4+4-pin EPS (CPU) power cable to the CPU power connector on your motherboard. This is usually located near the CPU socket. If your motherboard requires an 8-pin connector, combine the two 4-pin halves.
- Connecting PCIe Power (Graphics Cards): If you have a dedicated graphics card, connect the 6+2-pin PCIe power cables from the PSU to your graphics card(s). Some high-end graphics cards may require multiple PCIe power connectors.
- Connecting SATA/Molex Power: Connect SATA power cables to your storage drives (HDDs, SSDs) and optical drives. Use Molex connectors for any other peripherals that require them (e.g., case fans, fan controllers).
- Xestión de cables Route all cables neatly to improve airflow and aesthetics within your PC case. Use cable ties or straps if necessary.
- Verificación final: Double-check all connections to ensure they are secure and correctly seated. Close your PC case.
- Encendido: Connect the AC power cord to the PSU and then to a wall outlet. Flip the power switch on the back of the PSU to the 'ON' position. You can now power on your computer.

7 Solución de problemas
If you encounter issues with your COUGAR GX-S 750W PSU, refer to the following troubleshooting steps:
- O sistema non se acende:
- Asegúrate de que o cable de alimentación de CA estea conectado correctamente tanto á fonte de alimentación como á toma de corrente.
- Comprobe que o interruptor de alimentación da parte traseira da fonte de alimentación estea na posición "ON".
- Verify that the 24-pin ATX and 4+4-pin CPU power cables are correctly connected to the motherboard.
- Proba a toma de corrente con outro dispositivo para confirmar que teña corrente.
- O sistema acende pero apágase inmediatamente:
- This could indicate a short circuit or an overloaded component. Disconnect all non-essential components (e.g., extra drives, graphics card) and try powering on. Reconnect one by one to identify the problematic component.
- Ensure all components are compatible with the PSU's wattage.
- Ruído excesivo do ventilador:
- Check for dust buildup on the fan grille and clean if necessary (after disconnecting power).
- Ensure the PSU is securely mounted and not vibrating against the case.
- High fan speed can be normal under heavy system load. Monitor system temperatures.
- Inestabilidade/fallos do sistema:
- Ensure all power connectors are firmly seated.
- Verify that your system's power requirements do not exceed the PSU's 750W capacity.
- This could also be related to other components (RAM, CPU, GPU). Test components individually if possible.
