Product information

Description

The NZXT C850 Gold Core 850 W is a fully modular ATX 3.1 power supply designed for modern performance PCs. It provides 850 W of continuous power with 80 PLUS Gold and Cybenetics Platinum efficiency, a 24-pin ATX main connector, and an active 135 mm fluid dynamic bearing fan with Zero RPM mode. The unit includes a dual-color 12V-2x6 (PCIe 5.1) GPU connector and up to three 8-pin PCIe cables for broad GPU compatibility, all in a compact 150 mm length and black finish.

Advantages

The PSU delivers energy-efficient performance and reduced heat thanks to 80 PLUS Gold certification and Cybenetics Platinum efficiency. Noise is minimized by Cybenetics-certified ratings and a 135 mm FDB fan with Zero RPM mode, allowing near-silent operation at light loads. High-quality 105°C-rated capacitors and built-in protections ensure voltage stability and long-term reliability. Fully modular, embossed cables simplify cable management and keep builds clean, while the 12V-2x6 dual-color connector supports next-generation GPUs with a secure connection indication. A 7-year warranty covers the product.

Suitable for

High-performance gaming PCs with NVIDIA or AMD graphics cards
Workstation builds requiring stable 850 W power delivery
Systems that benefit from modular cabling and compact PSU length

How to use

Install the NZXT C850 Gold Core into a compatible ATX case, securing it with the provided screws and connecting the 24-pin ATX cable to the motherboard. Use the modular PCIe cables to connect the 12V-2x6 or 8-pin GPU power plugs to your graphics card(s), ensuring the dual-color connector seats fully for a correct connection. Connect remaining modular cables (SATA, peripheral) as needed, then connect the AC power cord to a suitable mains outlet. The fan operates automatically and enters Zero RPM mode under light loads.

Usage recommendations

Use the included embossed, modular cables and combs to route cables neatly and avoid obstructing airflow. Ensure the 12V-2x6 connector is fully engaged and rated for 105°C where high GPU power is required. Verify compatibility with your GPU power requirements before installation and allow adequate case ventilation for sustained heavy loads.
