The NZXT C850 is an ATX 3.1 power supply unit that provides a total power output of 850 watts. It holds an 80 PLUS Gold certification, indicating high operational efficiency under typical load conditions. The unit incorporates active Power Factor Correction (PFC) to maintain stable and consistent power delivery to system components. Its compliance with the ATX 3.1 standard makes it suitable for use with current-generation hardware that requires precise power handling, including modern graphics cards.
This PSU features a fully modular cabling system, which allows users to connect only the necessary cables for improved airflow and a cleaner build aesthetic. Cooling is managed by a single 135 mm fan with a fluid dynamic bearing, operating with an active cooling profile and a rated noise level up to 44.5 dB. The unit is equipped with a comprehensive suite of protection circuits, including over-voltage, over-power, and short-circuit protection. Its standard ATX form factor and 160 mm depth ensure compatibility with a wide range of computer chassis.
