3.3 Conexión de alimentación

1. Connect the AC power cord to the PSU's power inlet.
2. Plug the other end of the AC power cord into a wall outlet.

4. Instrucións de funcionamento

4.1 Acendido/Apagado

1. Flip the power switch on the back of the PSU to the 'ON' (I) position.
2. Preme o botón de acendido da caixa do teu ordenador para iniciar o sistema.
3. To power off, shut down your operating system normally, then flip the PSU power switch to the 'OFF' (O) position if desired for complete power disconnection.

4.2 Semi-Passive Cooling (Zero-RPM Mode)

The Power Zone 2 features a semi-passive cooling mode. The 140mm Pure Wings 3 fan will remain inactive under low system loads, ensuring near-silent operation. As the system load increases and internal temperatures rise, the fan will automatically activate to maintain optimal cooling.

Figura 5: The semi-passive cooling feature ensures the fan remains off during low loads for silent operation, activating only when needed.

After the system load decreases, the fan may continue to spin for 2-5 minutes to ensure proper cooldown before returning to zero-RPM mode. This behavior is normal and designed to prevent frequent fan starts and stops, contributing to fan longevity and quietness.

Figura 6: The fan may run for a short cooldown period (2-5 minutes) after heavy loads to ensure optimal thermal management and prevent frequent cycling.

5. Mantemento

To ensure the longevity and optimal performance of your Power Zone 2 PSU, follow these maintenance guidelines:

• Limpeza: Periodically clean the exterior of the PSU and the fan grille to prevent dust buildup. Use a soft, dry cloth or compressed air. Ensure the power supply is turned off and unplugged before cleaning.
• Fluxo de aire: Ensure adequate airflow around the power supply. Do not obstruct the fan intake or exhaust vents.
• Xestión de cables Regularly check that all modular cables are securely connected and not obstructing airflow within the PC case.

6 Solución de problemas

If you encounter issues with your Power Zone 2 PSU, consider the following common troubleshooting steps:

• Sen enerxía: Ensure the AC power cord is securely connected to both the PSU and the wall outlet. Verify that the PSU's power switch is in the 'ON' (I) position. Check your wall outlet with another device.
• O sistema non arranca: Double-check all modular cable connections, especially the 24-pin motherboard connector and the 8-pin CPU power connector. Ensure your graphics card(s) are properly seated and powered.
• Intermittent Shutdowns: This could indicate an overload or overheating. Ensure your system's power requirements do not exceed the PSU's 750W capacity. Check for proper ventilation and dust buildup.
• O ventilador non xira: Remember that the Power Zone 2 operates in semi-passive mode. The fan will only spin under sufficient load. If your system is under load and the fan is still not spinning, or if you notice overheating, contact support.

If these steps do not resolve your issue, please refer to the warranty and support section for further assistance.
