Product information

Description

FOCUS GX ATX 3.0 is a high-efficiency power supply designed to meet ATX 3.0 and PCIe 5.0 standards. Available in compact 140 mm depth models from 750 W to 1000 W, the unit provides stable power delivery for modern high-performance graphics cards and processors. The supply features Seasonic's Digital Hybrid Fan Control and a Fluid Dynamic Bearing fan for balanced cooling and reduced noise.

Advantages

The power supply delivers 80 PLUS Gold efficiency and a fully modular cable design that simplifies installation and cable management. Digital Hybrid Fan Control offers three operating modes — fanless, silent and cooling — to optimize noise and thermal performance. A Fluid Dynamic Bearing fan reduces mechanical noise and extends fan lifespan through improved lubrication and reduced friction.

Key specifications

  • Efficiency rating: 80 PLUS® GOLD
  • Form factor compatibility: ATX 3.0 & PCIe 5.0
  • Wattage: 850 W (model example shown), input: 100–240 V, 50/60 Hz
  • Modularity: Fully modular cables
  • Motherboard connector: 20+4 pin ATX
  • Cooling: 135 mm Fluid Dynamic Bearing fan
  • Color: White

How to use

Install the power supply into a compatible ATX chassis, secure it with screws, and connect the fully modular cables to the motherboard, graphics card and peripherals according to component requirements. Ensure input voltage matches the local mains (100–240 V). After powering the system on, the Digital Hybrid Fan Control will automatically select Fanless, Silent or Cooling mode depending on thermal load.

Recommendations

For reliable operation, use this PSU with motherboards and GPUs that support ATX 3.0/PCIe 5.0 power delivery. Keep the PSU intake area free of dust, verify that the chassis supports a 140 mm deep unit, and periodically clean the fan and ventilation openings to maintain optimal cooling performance.
