Product information

Description

The ASUS Prime -850G is an ATX power supply unit that delivers 850 W of continuous power with 80 PLUS Gold efficiency and active power factor correction (PFC). Designed for desktop systems that require stable and efficient power delivery, it features a 20+4 pin ATX motherboard connector and a range of peripheral cables for common PC components. The unit is finished in black and is intended for builds where reliable performance and energy efficiency are priorities.

Advantages

The Prime -850G combines high efficiency with durable cooling and modular cabling to support sustained loads. 80 PLUS Gold certification indicates lower energy losses and reduced heat output compared with lower-efficiency units. The design includes long-lasting fan bearings and fully modular cables to simplify system assembly and cable management, while active PFC improves voltage stability under varying loads.

Suitable for

  • High-performance desktop workstations that require steady, efficient power delivery
  • Gaming PCs with discrete graphics and multiple drives
  • All-round PCs used for content creation, streaming, or multitasking

Key specifications

  • Total power: 850 W
  • Motherboard power connector: 20+4 pin ATX
  • Efficiency certification: 80 PLUS Gold
  • Cooling: active fan with dual-ball bearing design
  • Operating input range: 100 - 240 V
  • Product colour: Black
  • Weight: 1.48 kg

How to use

Install the ASUS Prime -850G into a compatible ATX case, secure it to the PSU mounting points, and connect the 20+4 pin ATX cable to the motherboard. Attach the included CPU, PCIe, SATA and Molex cables to the corresponding components, ensuring all connectors are fully seated. Verify correct input voltage and power on the system; monitor voltages and system stability during initial use. Observe standard safety practices: disconnect mains power before making internal connections and avoid obstructing the fan intake and exhaust paths.

Usage recommendations

Match the power supply to your system’s cumulative power draw with headroom for peak loads; for multi-GPU or highly overclocked configurations, plan for additional capacity. Keep ventilation clear and perform periodic dust removal to preserve cooling efficiency and prolong fan life.
