NZXT C850 80 PLUS Gold Fully Modular Power Supply, 850W, ATX12V v3.1, Fluid Dynamic Bearing, 80 Plus Gold, Japanese Capacitors, Active PF Correction, Matte White | PA-8G2BW-UK

High-Performance Power: ATX 3.1 & PCIe 5.1 Ready

The C850 Gold has been re-engineered to support the most advanced PC hardware. Fully compliant with ATX 3.1 and PCIe 5.1 standards, this PSU is built to handle the massive instantaneous power excursions (transient spikes) common in modern enthusiast GPUs. It includes a native 16-pin 12V-2x6 cable, delivering up to 450W of direct power to your graphics card. This updated connector standard offers improved physical seating and thermal reliability compared to the original 12VHPWR design.

Elite Efficiency and Thermal Management

Boasting an 80 PLUS Gold certification, the C850 operates with up to $90\%$ efficiency at typical loads. This reduces heat waste and energy consumption, ensuring a more sustainable and cooler-running system. Thermal management is handled by a 135mm Fluid Dynamic Bearing (FDB) fan, which provides superior cooling performance with minimal noise. For total silence during light workloads, the integrated Zero RPM Fan Mode can be toggled via a physical button, keeping the fan completely still until the system is pushed.

Industrial-Grade Reliability & Japanese Capacitors

Reliability is the core of the NZXT C-Series. The C850 is constructed using 100% Japanese $105^\circ\text{C}$ electrolytic capacitors, ensuring industrial-grade durability and rock-solid voltage regulation. These premium components, combined with Active Power Factor Correction (PFC), safeguard your sensitive CPU and motherboard from electrical inconsistencies, providing a stable foundation for gaming or professional creative work.

Sleek Matte White Design for Clean Builds

Perfect for the modern aesthetic, the Matte White finish of the C850 makes it an ideal centerpiece for "Snow" themed builds. The unit is fully modular, allowing you to use only the cables your build requires to maximize airflow and minimize clutter. The included cables are high-quality and flexible, making cable management in NZXT H-series or dual-chamber cases effortless and visually stunning.
