The Corsair HX850 is a high-performance power supply unit engineered to provide clean, stable power to demanding PC components. With its 80 PLUS Platinum certification, this unit achieves up to 92% efficiency, effectively reducing power waste, lowering heat generation, and ensuring quieter operation under load.

Designed for enthusiasts, the HX850 utilizes a fully digital platform with resonant LLC topology and DC-to-DC conversion to maintain steady power delivery while eliminating coil whine. The fully modular cabling system allows users to connect only the necessary cables, simplifying cable management and optimizing internal chassis airflow.

Cooling is handled by a 140mm fluid dynamic bearing fan, which uses a specialized curve to balance temperature and noise.
