White 850 W ATX Power Supply

The Corn Electronics GX 850 delivers 850 W of continuous power in a white ATX form factor. It targets builders who want a fully modular unit with a clean aesthetic for mid-to-high-end systems. The single +12 V rail design simplifies load balancing across components. This unit suits gaming rigs and workstations that demand stable, efficient delivery.

80 Plus Gold Efficiency and Protection

Rated at 80 Plus Gold, the supply exceeds 90 % efficiency at typical loads, reducing waste heat and electricity draw. Active PFC corrects the power factor across a 100–240 V, 50/60 Hz input range. Over-voltage and overload protection circuits guard connected hardware. The LLC resonant topology with synchronous rectification and DC-DC conversion maintains tight regulation.

850 W Capacity With 4090-Class Headroom

Four 6+2-pin PCIe connectors support modern graphics cards including the 4090 tier, while nine SATA connectors handle multiple drives. The 140 mm fan stays off below 20 % load for silent idle operation. At 150 mm depth the unit fits most standard ATX cases. Builds requiring more than 850 W or additional PCIe cables will need a higher-rated platform.

Questions about this item

Should I pick the 850 W version or look for a different capacity?

This model is offered only as an 850 W unit, so there is no alternative capacity to compare.

What does the 850 W rating actually deliver inside my PC?

The 850 W figure is the maximum continuous output the supply can sustain across all rails while staying within its 90 % efficiency target.

Does the ATX form factor and active PFC limit what I can connect?

The ATX layout with active PFC fits standard cases and works on 100-240 V mains, while the full-modular cables let you attach only the connectors your build needs.
