The Antec HCG 850 PRO is an 850W power supply designed for high-performance PC systems. It operates with 80 PLUS Platinum certified efficiency, which minimizes heat waste and reduces energy consumption under load. Compliant with the ATX 3.1 and PCIe 5.1 standards, it is equipped to handle the power excursions of modern graphics cards and processors. Its native 12V-2x6 connector provides direct power to compatible components, and the fully modular design allows builders to use only necessary cables, simplifying installation and improving internal airflow.
Cooling is managed by a 135 mm fan that provides effective heat dissipation while maintaining low operational noise, further supported by a silent mode under light loads. Housed in a standard ATX chassis measuring 160 mm in depth, it ensures compatibility with a wide range of computer cases. A comprehensive suite of power protection features is integrated, including over-current, over-power, and short circuit protection, to safeguard system components. The active Power Factor Correction contributes to stable and clean power delivery during operation.
