This article covers NZXT C1200 ゴールド ATX 3.1.

Overview

The NZXT C1200 Gold ATX 3.1 White is a 1200W power supply unit with 80PLUS GOLD certification, designed for high-end PC builds. It fully complies with the ATX 3.1 standard, ensuring stable power delivery even under transient peaks from modern graphics cards. The unit features a native 12V-2x6 connector, making it an ideal match for NVIDIA GeForce RTX 40-series GPUs. Premium 100% Japanese capacitors reduce ripple noise and improve hold-up time, while the 135mm fluid dynamic bearing fan remains completely silent under 50% load thanks to its zero-RPM mode. Fully modular cabling allows you to connect only the cables you need, simplifying installation and improving airflow inside the case. The white finish blends seamlessly with NZXT's white chassis and other white components, appealing to builders who prioritize aesthetic consistency.

Compatibility Guide

The NZXT C1200 Gold ATX 3.1 White follows the standard ATX form factor, fitting most mid-tower and full-tower cases. Its depth of approximately 150mm leaves ample room for cable management. The unit includes two EPS12V connectors for high-end motherboards and overclocking setups. The native 12V-2x6 connector directly powers RTX 40-series cards without adapters. Adapters for older GPUs (6+2 pin PCIe) are also provided, ensuring broad compatibility with previous-generation graphics cards.

Product Info

Released in late 2024, the NZXT C1200 Gold ATX 3.1 White occupies the mid-high segment of the power supply market. It offers 1200W capacity and 80PLUS GOLD efficiency at a more accessible price point than platinum-rated units, while still incorporating premium components such as Japanese capacitors and a fluid dynamic bearing fan. The manufacturer provides a 10-year warranty, reflecting confidence in long-term reliability.

Best Use Cases

High-end gaming PCs: With flagship GPUs like RTX 4090/5080 and top-tier CPUs (Core i9/Ryzen 9), the 1200W headroom ensures stable operation under heavy loads. The native 12V-2x6 connector enhances safety and convenience. Silence-focused builds: The zero-RPM fan mode keeps the system inaudible during everyday tasks and moderate gaming. The fluid dynamic bearing maintains low noise over years of use. * White-themed PC builds: Ideal for users building a white PC with NZXT cases or other white components. The fully modular white cables contribute to a clean, unified look.

Things to Consider

1200W is overkill for typical mid-range systems (e.g., RTX 4070 SUPER + Ryzen 5), where a 750W or 850W unit would suffice. Evaluate your actual power requirements before purchasing. Additionally, some compact cases (especially Mini-ITX) may not accommodate a 150mm-deep PSU; measure your case's PSU bay beforehand. Competitors like Seasonic Vertex GX-1200 and Corsair RM1200x Gold offer similar specifications, often at slightly lower prices. Consider your budget and which features (silence, aesthetics, warranty) matter most to you.
