## Long 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.
