Product information

Description

FSP DAGGER PRO ATX3.0 (PCIe5.0) 850W is a compact SFX power supply designed to deliver up to 850 W of continuous power for small-form-factor high-performance systems. Compatible with ATX3.0 and PCIe5.0 requirements, this unit supports modern GPUs and CPUs while maintaining energy efficiency through its 80 PLUS Gold rating. The supply accepts 100–240 V AC input at 50/60 Hz and comes with a 20+4 pin ATX motherboard lead and a selection of peripheral connectors, enabling installation in compact gaming rigs and workstation builds.

Advantages

The FSP DAGGER PRO 850W combines high output in an SFX enclosure with 80 PLUS Gold efficiency to reduce wasted energy and thermal load. Its ATX3.0/PCIe5.0 compatibility ensures it supports current power delivery standards for next-generation graphics cards. A 92 mm active cooling fan provides targeted airflow in constrained cases, while a range of included cables (20+4 pin ATX, SATA, PCIe, CPU, and peripheral) simplifies cable routing and component connectivity in compact builds.

Suitable for

  • Compact gaming PCs and mini-ITX or micro-ATX high-performance systems
  • Workstations requiring reliable, efficient power in small enclosures
  • Builds using PCIe5.0-capable graphics cards and ATX3.0 motherboards
  • Users seeking an 80 PLUS Gold certified SFX power supply

Key specifications

  • Total power output: 850 W
  • Efficiency level: approximately 90% (80 PLUS Gold)
  • Form factor: SFX
  • Input voltage/frequency: 100–240 V AC, 50/60 Hz
  • Motherboard connector: 20+4 pin ATX (cable length 35 cm)
  • Cooling: 92 mm fan
  • Color: Black

How to use

Install the FSP DAGGER PRO 850W into a compatible SFX mounting location within your case, observing orientation for optimal airflow toward the 92 mm fan. Connect the 20+4 pin ATX cable to the motherboard, then attach CPU power and PCIe connectors to the processor and graphics card as required. Use the provided SATA and peripheral leads for storage drives and accessories. Ensure all connections are secure before powering on the system and verify BIOS/firmware settings for power delivery where applicable.

Usage recommendations

Place the unit in an enclosure with adequate ventilation to allow the 92 mm fan to dissipate heat efficiently. Match cable routing to your case layout to avoid obstructing airflow. For stable performance with high-draw graphics cards, confirm that the PSU is installed according to ATX3.0 guidelines and that PCIe power cables are connected directly as required by the GPU manufacturer.
