Setup and Installation

Follow these steps to properly install your FSP Dagger Pro SFX Power Supply:

1. Prepare Your System: Ensure your computer is completely powered off and unplugged from the wall outlet. Open your PC case to access the PSU mounting area.
2. Mount the PSU:
   • For SFX cases: Align the Dagger Pro PSU with the SFX mounting holes in your case and secure it with the provided mounting screws.
   • For ATX cases: Attach the included SFX to ATX adapter bracket to the Dagger Pro PSU using the provided screws. Then, mount the PSU with the adapter bracket into the ATX PSU bay of your case and secure it.

3. Connect Modular Cables: Identify the necessary cables for your motherboard, CPU, graphics card(s), and storage devices. Connect one end of each required modular cable to the corresponding port on the PSU. The ports are clearly labeled (e.g., MOTHERBOARD, CPU, PCI-e, PERIPHERAL).
4. Connect Components: Route the modular cables neatly through your case and connect the other end of each cable to the corresponding component (e.g., 20+4 pin ATX to motherboard, 4+4 pin EPS to CPU, 6+2 pin PCIe to graphics card, SATA to SSD/HDD).
5. Secure Cables: Use cable ties or straps to manage cables, ensuring they do not obstruct airflow or interfere with other components.
6. Close Case and Connect Power: Close your PC case. Connect the AC power cord to the power supply's AC inlet and then plug the other end into a grounded wall outlet.
7. Power On: Flip the power switch on the back of the PSU to the 'ON' position. You can now power on your computer.

Operating Principles

The FSP Dagger Pro 650W PSU operates with advanced features to ensure stable and efficient power delivery:

• Semi-Fanless Operation: The integrated 92mm fan is designed to remain off under low load conditions (typically below 20% of total wattage) for silent operation. As the system load increases and the internal temperature rises, the fan will automatically spin up to provide necessary cooling. This intelligent design extends fan lifespan and reduces noise.
• Single +12V Rail Design: This PSU features a robust single +12V rail, which provides the full available wattage to your system's components, particularly high-power devices like graphics cards. This design simplifies power distribution and helps prevent potential overcurrent issues that can occur with multiple, lower-amperage +12V rails.

Maintenance and Care

Proper maintenance can extend the life of your power supply and ensure continued optimal performance:

• Dust Removal: Periodically (every 3-6 months, depending on environment) power off your PC, unplug the power cord, and use compressed air to gently blow dust out of the PSU's fan grill and ventilation openings. Accumulation of dust can hinder cooling and reduce efficiency.
• Cable Management: Ensure cables inside your PC case are neatly managed and do not block airflow to the PSU or other components.
• Environmental Conditions: Operate the PSU in a clean, dry, and well-ventilated environment. Avoid placing your PC in areas with excessive dust, humidity, or direct sunlight.
• Do Not Disassemble: Never attempt to open the power supply unit. It contains high voltage components and is not user-serviceable. Opening the unit will void the warranty and poses a risk of electric shock.
