The NZXT C-Series 850W is an ATX power supply designed to provide consistent and stable power for high-performance PC builds. It delivers a total output of 850 watts and holds an 80 Plus Gold certification, indicating high efficiency during energy conversion which minimizes wasted heat. The fully modular design allows builders to use only the cables required for their components, simplifying the installation process and improving internal airflow. Its adherence to ATX 2.52 and EPS12V 2.92 standards ensures broad compatibility with most modern motherboards.
System cooling is managed by a single 135 mm fan that operates on a variable curve from 0 to 2300 RPM, adjusting its speed based on thermal load. This configuration enables quiet operation during idle or low-power tasks, as the fan can stop spinning entirely. The unit integrates active Power Factor Correction for stable power delivery and is rated for a mean time between failures of 100,000 hours. The included power cables, such as the 700 mm CPU and 650 mm PCIe cables, offer sufficient length for routing in various chassis sizes.
