The NZXT C850 is an ATX power supply unit designed to deliver 850 watts of continuous power for PC systems. It is built on the ATX 3.1 standard, which supports high transient power demands from modern graphics cards and processors. With an 80 PLUS Gold certification, the unit operates with high efficiency to minimize wasted heat and energy consumption. Its active Power Factor Correction circuitry further ensures stable and reliable voltage regulation for all connected components.
This model utilizes a fully modular design, allowing for the use of only essential cables to facilitate cleaner system builds and better internal airflow. A 135 mm fan handles thermal management and is engineered for low-noise operation, including a silent mode for periods of low system load. The power supply is housed within a standard ATX enclosure measuring 160 mm in depth, fitting a wide range of computer cases. For system reliability, it incorporates a full suite of protections such as OVP, UVP, SCP, and OPP.
