Product information

Description

ENERMAX ERV850G-AHG-NAC is a non-modular desktop power supply unit with 850 W total output designed for ATX PC builds. It features a 20+4 pin ATX motherboard connector, a 120 mm cooling fan and black flat cables. The unit is 80 PLUS Gold certified for high energy efficiency and accepts universal input voltage from 100 to 240 V at 50/60 Hz, providing stable power delivery for gaming rigs, workstations and high-performance systems.

Advantages

This ENERMAX 850 W PSU delivers efficient power conversion with 80 PLUS Gold certification, helping to reduce wasted energy and heat. The non-modular black flat cable design simplifies installation and routing inside the case. A 120 mm fan provides active cooling while maintaining a compact form factor suitable for standard ATX builds. The 20+4 pin ATX connector ensures compatibility with a broad range of motherboards.

Suitable for

  • Gaming desktop systems with mid to high power demand
  • Home or office workstations requiring stable 850 W supply
  • Upgrades where non-modular cabling and compact cooling are acceptable
  • Systems requiring 80 PLUS Gold efficiency to reduce energy loss

Key specifications

  • Total power: 850 W
  • Motherboard power connector: 20+4 pin ATX
  • Efficiency certification: 80 PLUS Gold
  • Cooling fan: 120 mm
  • Input voltage: 100–240 V, 50/60 Hz
  • Cable type: Non-modular black flat cables
  • Product colour: Black

How to use

Install the ENERMAX ERV850G-AHG-NAC into a compatible ATX case following standard PSU mounting orientation so the 120 mm fan has adequate airflow. Connect the 20+4 pin ATX cable to the motherboard main power socket and attach the remaining cables to drives and peripherals as required. Ensure the system power switch is off before making connections and verify that the input voltage selector (if present) matches your mains supply. After powering on, monitor system stability and temperatures to confirm reliable operation.

Usage recommendations

Use this PSU in systems that match its 850 W capacity; avoid relying on it for sustained loads above its rated power. Maintain case airflow to support the 120 mm fan, keep cables organized to improve ventilation, and allow clearance around ventilation openings. For optimal longevity, operate the unit within ambient temperatures and voltages recommended by your system’s components.
