Product Description
NZXT C850W Gold Reliable ATX 3.1 Power for High-Performance PCs

Efficient Power Delivery for Modern Components
The NZXT C850W is a premium power supply built for performance-focused PC builds requiring efficiency, stability, and high compatibility. With full compliance to the latest ATX 3.1 standard, this PSU ensures exceptional power regulation, better spike handling, and precise delivery to even the most power-hungry components, including next-gen GPUs. Its 850W output provides ample headroom for high-end processors and graphics cards while maintaining optimal energy efficiency.
Clean Builds with Silent Cooling
Designed with builders in mind, the fully modular layout of the C850W lets you connect only the necessary cables, leading to a neater interior and improved airflow. It features a 135mm fluid dynamic bearing fan that operates in Zero Fan Mode under 50% load, offering virtually silent performance during low to medium workloads. Whether you're gaming, creating, or multitasking, this PSU keeps your system cool and quiet.

Reliable, Durable, and Ready for the Future
With 80 Plus Gold certification, the C850W minimizes energy waste and reduces heat generation. Premium internal components, including all-Japanese capacitors, ensure long-term durability and outstanding hold-up time. Backed by a 10-year warranty, this PSU is engineered for long-lasting performance, giving you the peace of mind and reliability you need for years of computing excellence.
