- Mount the New PSU: Carefully place the FSP Hydro G PRO 1000W Power Supply into the designated bay in your computer case. Secure it with the provided mounting screws. Ensure the fan is oriented correctly for optimal airflow (typically facing downwards if your case has a bottom vent, or upwards if not).
- Connect Modular Cables: Identify the necessary cables for your components. This power supply is fully modular, allowing you to connect only the cables you need. Refer to the connection panel diagram below.
- Motherboard: Connect the 24-pin ATX cable to the 'MOTHERBOARD' port on the PSU and to your motherboard.
- CPU: Connect the 4+4-pin or 8-pin CPU power cable(s) to the 'CPU' port(s) on the PSU and to your motherboard.
- PCIe (Graphics Cards): Connect the 6+2-pin PCIe cables or the native 12V-2x6 cable to the 'PCIe' port(s) on the PSU and to your graphics card(s). The 12V-2x6 connector is designed for high-power graphics cards.
- Peripherals (SATA/Molex): Connect SATA power cables for SSDs/HDDs and Molex cables for other peripherals to the 'PERIPHERAL' ports on the PSU.
- Cable Management: Route cables neatly to improve airflow and aesthetics within your case.
- Final Connection: Once all internal connections are made, close your computer case. Connect the AC power cord to the power supply's inlet and then to a grounded wall outlet.

5. Operating Instructions
After installation, follow these steps to operate your power supply:
- Power On: Ensure the main power switch on the rear of the power supply is in the 'ON' (I) position. Then, power on your computer using its case power button.
- Eco Mode: The FSP Hydro G PRO features an Eco switch. When the Eco switch is engaged (ON), the power supply fan will remain off under loads below 30% of the PSU's rated power, providing silent operation. The fan will automatically activate when the load exceeds 30% or when temperatures rise. If the Eco switch is disengaged (OFF), the fan will operate continuously.
