This article covers NZXT C850 ゴールドコア.

Overview

The NZXT C850 Gold Core is an 850W ATX 3.1 compliant power supply that delivers clean and stable power for modern PC builds. It is 80 PLUS Gold certified and also holds Cybenetics Platinum efficiency, ensuring high efficiency across the load range. The fully modular design simplifies cable management, while the 135mm FDB fan features zero RPM mode for silent operation under light loads. With PCIe 5.1 support and a 600W 12V-2x6 connector, it is ready for today's and tomorrow's graphics cards. This PSU uses 105°C-rated Japanese capacitors for long-term reliability and is Cybenetics A++ certified for noise (under 15 dBA). The dual-color 12V-2x6 connector ensures a secure connection, reducing the risk of improper seating. It is an excellent choice for mid-to-high-end gaming and productivity systems.

Compatibility Guide

The NZXT C850 Gold Core is a standard ATX form factor power supply (150x140x86mm) and fits most ATX and E-ATX cases with sufficient clearance. It provides two EPS 12V 8-pin connectors for CPU power, one 12V-2x6 (PCIe 5.1) cable, three 8-pin PCIe cables, twelve SATA power connectors, and four Molex connectors. This connectivity supports multi-GPU setups (though rare), multiple storage drives, and various peripherals. With 850W capacity, it can comfortably handle a system with a mid-to-high-end CPU (e.g., Ryzen 7 7800X3D or Core i7-14700K) and a high-end GPU (e.g., RTX 4070 Ti Super or RX 7900 XT). The fully modular cables allow you to use only the necessary cables, reducing clutter. Always check your case's PSU clearance, especially if using a compact case.

Product Info

The NZXT C850 Gold Core (model PA-8G3BB) positions itself in the mid-to-high-end market segment. It combines 80 PLUS Gold certification with Cybenetics Platinum efficiency, a rare combination at this price point. The unit is backed by a 10-year warranty (standard for NZXT PSUs). Key features include ATX 3.1 compliance, PCIe 5.1 with 600W 12V-2x6 connector, 135mm FDB fan with zero RPM mode, and 105°C capacitors. Cybenetics Noise rating A++ (<15 dBA) confirms its near-silent operation.

Best Use Cases

High-performance gaming builds: Ideal for systems with an RTX 5070 or RX 9070-class GPU, providing ample headroom for gaming workloads and future upgrades. The ATX 3.1 standard ensures stable operation under transient loads. Silent-focused workstations: Content creators who value a quiet environment will appreciate the zero RPM mode and A++ noise rating. The efficient design also reduces heat output, contributing to a cooler system. * Modularity enthusiasts: The fully modular cabling makes cable routing clean and straightforward, perfect for builders who prioritize aesthetics and easy maintenance.

Things to Consider

While 850W is sufficient for most single-GPU configurations, users planning to run a flagship GPU like the RTX 5090 or RX 7950 XTX may want to consider a 1000W unit for extra headroom, especially if also overclocking the CPU. The 12V-2x6 connector must be fully inserted; improper seating can cause overheating. Additionally, the physical size (140mm depth) may be tight in some small form factor cases, so measure your case's PSU bay before purchase. The price of ¥46,634 ( Japan as of May 2026) is competitive for a unit with this feature set and certification.
