Product information

Description

Enermax ERV850G-AHG-MAC is a fully modular ATX power supply delivering 850 W of continuous power with 80 PLUS Gold efficiency. It supports universal 100–240 V AC input at 50/60 Hz and includes a 20+4 pin ATX motherboard connector. Designed for desktop PC builds that require stable and efficient power delivery, it features premium mesh-sleeved cables, a 120 mm fluid dynamic bearing fan, and industrial-grade components for reliable operation.

Advantages

The unit is 80 PLUS Gold certified, offering up to 93% efficiency under typical loads, which reduces heat and energy waste. It uses 100% industrial-grade Japanese capacitors to maintain consistent voltage and longevity. The 120 mm F.D.B. fan ensures quiet cooling, while the fully modular design and individually mesh-sleeved cables with cable combs simplify cable routing and create a tidy build. The power supply is ATX 3.1 ready and rated to operate continuously at up to 40°C and at altitudes up to 5,000 meters.

Suitable for

  • Gaming desktops with high-performance graphics cards
  • Workstations requiring stable 12V power rails
  • Custom PC builds where clean cable management is desired
  • Environments at higher altitudes or warmer ambient temperatures

When it may not be suitable

This 850 W power supply may be excessive for very basic office or home PCs with low-power CPUs and integrated graphics, where lower-wattage, lower-cost units would suffice. It may also be unnecessary for small form-factor systems that cannot accommodate standard ATX PSUs or where modular cable length and connector types do not match case constraints.

Key specifications

  • Output power: 850 W continuous
  • Efficiency: 80 PLUS Gold (up to ~93% typical)
  • Input voltage: 100–240 V AC, 50/60 Hz
  • Form factor: ATX
  • Motherboard connector: 20+4 pin ATX
  • Cooling: 120 mm Fluid Dynamic Bearing (FDB) fan
  • Capacitors: 100% industrial-grade Japanese capacitors
  • Cabling: Fully modular with individually mesh-sleeved cables and cable comb kit
  • Operating conditions: continuous operation up to 40°C and up to 5,000 m altitude
  • Color: Black

How to use

Install the Enermax ERV850G-AHG-MAC into a compatible ATX case and secure it with the provided screws. Connect the 20+4 pin ATX cable to the motherboard main power socket, then attach any required CPU, GPU and peripheral cables from the modular cable set. Only connect the cables you need to keep the interior tidy. Ensure input mains voltage matches the PSU rating and that the case has adequate ventilation. Power up the system and verify stable operation and proper fan function.

What to consider before purchase

  • System power requirements (total wattage including peak GPU/CPU draw)
  • Compatibility with your case (ATX form factor and cable routing space)
  • Required connectors and cable lengths for GPU, CPU and peripherals
  • Operating environment (high altitude or high ambient temperature needs)

Usage recommendations

For reliable performance, pair this 850 W Enermax ATX power supply with mid- to high-end CPUs and discrete GPUs, route only necessary modular cables for improved airflow, and ensure your case provides adequate ventilation to maintain operation within the specified 40°C limit.
