ENERMAX Power Supply Revolution III 850 Watt 80 Plus Gold Fully Modular ATX 3.1

ENERMAX ERV850G-AHG-MAC is an 850 W desktop power supply unit with 80 PLUS Gold certification and a fully modular cabling system. It delivers up to 93% efficiency under typical load, includes a 20+4 pin ATX motherboard connector and supports AC input from 100 to 240 V. The unit uses industrial-grade Japanese capacitors, a 120 mm fluid dynamic bearing fan and comes with premium mesh-sleeved cables and cable combs for tidy routing.

Advantages

The power supply meets Intel ATX 3.1 standards for compatibility with modern, power-hungry graphics cards and is certified to operate continuously at temperatures up to 40°C and altitudes up to 5,000 meters. Its 80 PLUS Gold certification ensures high efficiency (up to 93%), while 100% Japanese capacitors provide stable and reliable electrical performance. The 120 mm F.D.B. fan reduces noise without compromising cooling, and the fully modular design lets you connect only the cables you need for a cleaner build.

How to use

Install the power supply into a compatible ATX case following the case manufacturer’s instructions and secure it with the supplied screws. Connect the 20+4 pin ATX motherboard connector and any required modular cables for CPU, GPU and storage devices. Route modular cables using the included cable combs and mesh sleeves to maintain airflow and neatness. Ensure AC input matches the local mains voltage (100–240 V) and switch on the system.

Recommendations

For optimal longevity and performance, keep intake and exhaust airflow unobstructed, use the modular cables supplied by the manufacturer, and avoid exposing the unit to temperatures above 40°C. If operating at high altitude, confirm case ventilation is adequate to maintain cooling.
