Product information

Description

The FSP DAGGER PRO ATX3.0(PCIe5.0) 850W is a compact, high-efficiency power supply unit designed for modern PC systems. Delivering a total power output of 850 W and certified 80 PLUS Gold efficiency, this ATX3.0-compatible PSU supports an AC input range of 100–240 V at 50/60 Hz and includes a 20+4 pin ATX motherboard connector. The unit features a built-in active cooling solution with a 92 mm fan and comes in a black finish. Supplied cables include CPU, PCIe, Peripheral (Molex), and SATA, with cable lengths suited for typical mid-tower and compact builds.

Advantages

The FSP DAGGER PRO combines ATX3.0 and PCIe5.0 readiness with an 80 PLUS Gold efficiency rating, which helps reduce energy loss and heat generation under load. Its 850 W total output provides stable power for high-performance components while the 92 mm fan delivers targeted active cooling in a compact form factor. Cable selection includes essential connectors for modern motherboards, graphics cards, and storage devices, and measured cable lengths simplify routing in many chassis types.

Suitable for

  • Gaming PCs with mid to high power components
  • Compact and small-form-factor builds that require ATX3.0 compatibility
  • Workstations requiring reliable 24/7 operation and efficient power delivery
  • Systems using PCIe5.0-ready graphics cards

Key specifications

  • Total power output: 850 W
  • Efficiency: approximately 90% (80 PLUS Gold)
  • AC input voltage: 100–240 V
  • Input frequency: 50/60 Hz
  • Motherboard connector: 20+4 pin ATX (cable length 35 cm)
  • SATA power cable length: 450 mm
  • Fan: 92 mm active cooling
  • Compatibility: ATX3.0 and PCIe5.0-ready
  • Color: Black

How to use

Install the power supply into a compatible ATX chassis following the case manufacturer’s instructions, ensuring correct orientation for airflow and secure mounting. Connect the 20+4 pin ATX cable to the motherboard and attach the CPU, PCIe, SATA and peripheral connectors to the appropriate components. Verify AC input matches the local mains voltage (100–240 V) and ensure all connections are secure before powering on the system. Allow the PSU fan to operate unobstructed to maintain cooling efficiency.

Usage recommendations

For best results, use this PSU with systems whose total component power draw remains within the unit’s rated 850 W output and observe proper cable routing to avoid airflow obstruction. Maintain adequate case ventilation and periodically inspect cables and connections for wear or dust build-up. When pairing with high-end PCIe5.0 graphics cards, confirm required power connector types and ensure combined connector capacity meets the component specifications.
