- Exceptional Quiet Operation with Eco Switch: Includes an Eco switch that, when activated, optimizes power consumption and allows the fan to remain off under 30% load, providing a silent computing experience.
3. Configuració i instal·lació
Before installation, ensure your system components are compatible with an 850W power supply and that your PC case has adequate space for the unit (dimensions: 150mm L x 150mm W x 86mm H).
3.1 Desembalatge i inspecció
Carefully remove the power supply and all modular cables from the packaging. Inspect for any visible damage. If any damage is found, contact your retailer or FSP support immediately.
3.2 Muntatge de la font d'alimentació
- Position the power supply in the designated PSU bay of your PC case. Ensure the fan is oriented correctly for optimal airflow (typically facing downwards if your case has a bottom vent, or upwards if not).
- Secure the power supply to the case using the provided screws.
3.3 Connexió de cables modulars
The FSP Hydro G PRO is fully modular, allowing you to connect only the cables required for your system. Refer to the image below for the connector layout on the power supply unit.

- Alimentació de la placa base: Connecteu el cable ATX de 24 pins a la placa base.
- Potència de la CPU: Connect the 8-pin (4+4 pin) EPS/CPU cables to your motherboard's CPU power connectors. Modern motherboards may require one or two such connectors.
- PCIe Power (Graphics Cards): Use the appropriate PCIe cables for your graphics card(s). This unit includes a native 12V-2X6 connector for compatible PCIe 5.1 graphics cards. For older cards, use the standard 6+2 pin PCIe connectors.
- Potència perifèrica: Connect SATA power cables for storage drives (SSDs, HDDs) and other peripherals. Use Molex connectors for older devices or case fans if needed.
Ensure all connections are secure and properly seated. Route cables neatly to improve airflow and aesthetics.
4. Instruccions de funcionament
4.1 Encès inicial
- After all internal connections are made, connect the AC power cord to the power supply and then to a wall outlet.
- Flip the main power switch on the back of the power supply to the 'ON' position.
- Premeu el botó d'engegada de la caixa de l'ordinador per iniciar el sistema.
4.2 Eco Switch Functionality
The FSP Hydro G PRO features an Eco switch located on the rear panel. This switch controls the fan's operation based on load.

- When the Eco switch is ON, the power supply fan will not operate under low load (below 30%), providing a silent experience during low power consumption. The fan will automatically activate when the load exceeds 30% to maintain optimal cooling.
- When the Eco switch is OFF, the power supply fan will operate continuously, regardless of the load, providing constant airflow.
5. Manteniment
The FSP Hydro G PRO power supply is designed for long-term reliability with minimal maintenance.

- Eliminació de pols: Periodically inspect the power supply's fan intake and exhaust vents for dust accumulation. Use compressed air to gently clear any dust to ensure proper airflow and cooling. Ensure the power supply is turned off and unplugged before cleaning.
- Recobriment conformal: The unit features an "Off-Wet Technology" conformal coating, providing protection against dust, moisture, and stains. This reduces the need for frequent internal cleaning in typical environments.
6. Solució De Problemes
If you encounter issues with your FSP Hydro G PRO power supply, consider the following steps:
- Sense energia:
- Assegureu-vos que el cable d'alimentació de CA estigui connectat correctament tant a la font d'alimentació com a la presa de corrent.
- Verify that the main power switch on the back of the power supply is in the 'ON' position.
- Check all modular cables (24-pin ATX, CPU, PCIe, etc.) are firmly seated in both the power supply and the respective components.
- Proveu la presa de corrent amb un altre dispositiu per confirmar que subministra corrent.
- Inestabilitat del sistema/aturades aleatòries:
- Assegureu-vos que els requisits d'alimentació del vostre sistema no superin la capacitat de 850 W de la font d'alimentació.
- Check for proper ventilation around the power supply and within the PC case to prevent overheating.
- Verify that all power connectors are correctly installed and not loose.
- Fan Not Spinning (Eco Mode):
- If the Eco switch is ON, the fan is designed not to spin under low load (below 30%). This is normal operation. The fan will activate automatically when the system load increases.
- If the Eco switch is OFF and the fan is not spinning, ensure the power supply is receiving power and is not faulty.
If issues persist after performing these checks, contact FSP customer support or your retailer for further assistance.
