APEVIA CORP. ATX-GX850W Galaxy 850W 80+ Gold Semi-Modular Power Supply

Apevia ATX-GX850W Galaxy 850W Power Supply

The Apevia ATX-GX850W Galaxy is an 850W ATX power supply with 80+ Gold certification and semi-modular cabling. It delivers a single 12V rail rated at 66A alongside 3.3V and 5V rails at 20A each. A 135mm auto-thermally controlled fan manages airflow while Active PFC and Double Forward Converter topology maintain stable output. Heavy-duty protections guard against short-circuit, over-voltage, over-power and under-voltage events.

Suited for high-output ATX builds needing Gold

This unit fits builders assembling systems that require 850W of continuous power with 80+ Gold efficiency and a semi-modular cable set for cleaner routing. The connector complement includes one 20/24-pin main, two 4+4-pin EPS 12V, four 6+2-pin PCIe, four SATA, four peripheral and one floppy connector. Buyers whose cases only accept smaller form-factor supplies or who need fully modular cabling should consider other options.

Single 12V rail rated at 66A

The power supply provides its full 850W capacity through a single 12V rail delivering up to 66A, which determines whether the unit can handle the combined load of high-end graphics cards and multi-core processors. Minor rails supply 3.3V at 20A and 5V at 20A with a 5Vsb standby rail at 3A. The design complies with ATX 12V 2.3 and includes large Japanese capacitors for reliability.
