Seasonic Core GX-850-V2 850W ATX 3.1 80+ Gold White Power Supply

The Seasonic Core GX-850-V2 is a fully modular 850W unit for desktop and gaming systems with a bright look. It is built to the ATX 3.1 standard with PCIe 5.1 compatibility and ships with white braided cables, suiting it to white-themed cases.

Power & efficiency

The unit provides 850W with 80 PLUS Gold certification, an efficiency level that supports economical power conversion and keeps wasted energy and heat down in daily use. The output gives comfortable headroom for current gaming and desktop systems, and the ATX 3.1 standard fits it to present-generation platforms and graphics cards.

Cables & connectors

The design is fully modular, so you connect only the cables your system needs and keep the case interior tidy. A built-in 12V-2x6 cable serves newer graphics cards, and for owners of earlier cards a 12V-2x6 to dual 8-pin PCIe adapter is provided.

Reliability & cooling

Cooling relies on a 120mm HDB fan governed by Seasonic's S²FC fan control, balancing airflow against noise in everyday use. The compact 140mm CORE-series body eases installation in standard ATX cases, and the OptiSink design uses the internal space more effectively for heat dissipation.
