3. Configuració
3.1 Instal·lació física
- Assegureu-vos que l'ordinador estigui apagat i desendollat de la presa de corrent.
- If replacing an existing PSU, carefully remove it from your PC case.
- Position the Power Zone 2 PSU in the designated power supply bay of your PC case. For ATX cases, use the included adapter bracket if necessary to secure the SFX-L form factor PSU.
- Secure the PSU to the case using the provided screws.
3.2 Modular Cabling
The Power Zone 2 is a fully modular power supply, allowing you to connect only the cables required for your system, which improves airflow and cable management.

Figura 3: Clearly labeled modular ports on the Power Zone 2 PSU simplify cable management and ensure correct connections.
- Identify the necessary cables for your motherboard, CPU, graphics card(s), and storage devices.
- Connect the required cables to the corresponding labeled ports on the PSU. Refer to the diagram below for cable types and lengths.
- Route the cables neatly through your PC case to their respective components.
- Connect the cables to your motherboard (24-pin ATX, 8-pin CPU), graphics card(s) (12V-2x6 or 6+2-pin PCIe), and storage devices (SATA/PATA).

3.3 Connexió d'alimentació
- Connecteu el cable d'alimentació de CA a l'entrada d'alimentació de la font d'alimentació.
- Connecteu l'altre extrem del cable d'alimentació de CA a una presa de corrent.
4. Instruccions de funcionament
4.1 Engegada/apagada
- Gireu l'interruptor d'alimentació de la part posterior de la font d'alimentació a la posició "ON" (I).
- Premeu el botó d'engegada de la caixa de l'ordinador per iniciar el sistema.
- 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. Manteniment
To ensure the longevity and optimal performance of your Power Zone 2 PSU, follow these maintenance guidelines:
- Neteja: 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.
- Flux d'aire: Ensure adequate airflow around the power supply. Do not obstruct the fan intake or exhaust vents.
- Gestió de cables: Regularly check that all modular cables are securely connected and not obstructing airflow within the PC case.
6. Solució De Problemes
If you encounter issues with your Power Zone 2 PSU, consider the following common troubleshooting steps:
- Sense energia: 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.
- El sistema no arrenca: 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.
- El ventilador no gira: 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.
