What this supply delivers

The Corn Electronics RGB-850 Pro is an ATX12V power supply rated at 850 W with 80 PLUS Gold certification. It targets builders who want a fully modular unit that can run a high-end graphics card and keep cable routing clean.

The efficiency figure that matters

At typical loads the unit reaches 90 percent efficiency or higher, which means less waste heat and lower fan speeds. Derating begins at 40 °C, dropping from 100 percent to 80 percent capacity by 50 °C ambient temperature.

Steady output under load

A single +12 V rail provides stable DC power for demanding components. Protection circuits include OPP, OVP, UVP, OCP, OTP and SCP, while the 140 mm fluid-dynamic-bearing fan adjusts speed by temperature to maintain cooling during extended sessions.

Questions about this item

What does the 850 W rating mean for actual system builds?

The 850 W rating delivers up to 850 watts of continuous power with 90 % efficiency at typical loads, supporting high-end graphics cards and CPUs on a single +12 V rail.

How does the ATX12V form factor limit compatibility?

The ATX12V form factor fits standard ATX cases and motherboards, measuring 170 mm long, 150 mm wide and 86 mm high.

What clearance is needed for the 140 mm ARGB fan and modular cables?

Allow space for the 140 mm fan height plus flat black modular cables; the unit is 86 mm tall and 170 mm deep, so check case PSU clearance.
