The NZXT C850 is an 850-watt power supply unit compliant with the ATX 3.1 standard, designed for systems with high-demand components. It holds an 80 PLUS Gold certification, indicating high efficiency during operation to reduce wasted heat and energy consumption. The inclusion of a 12V-2x6 connector ensures native support for modern high-performance graphics cards without requiring adapters. Its fully modular design allows builders to use only necessary cables, which can simplify cable management and improve airflow within the chassis.
The internal construction utilizes Japanese-rated capacitors to support long-term reliability and stable power delivery under load. A 135 mm fan provides active cooling to maintain optimal operating temperatures for internal components. This model features a silent mode that stops the fan under low-load conditions, resulting in quieter operation during idle or light usage. The unit also incorporates a suite of protections, including over-voltage, over-power, and short circuit, to safeguard system components.
