This article covers NZXT C1000 Gold ATX 3.1 完全モジュラー PC ゲーム用電源.

Overview

The NZXT C1000 Gold ATX 3.1 is a fully modular 1000W power supply unit that fully complies with the latest ATX 3.1 standard. It carries 80 Plus Gold and Cybenetics Gold efficiency certifications, and also achieves a Cybenetics A noise-level rating, balancing high efficiency with quiet operation. The dynamic 135mm fan supports zero-fan mode, stopping completely under 50% load, making it silent during everyday light usage. Internally, 100% Japanese capacitors ensure long-term reliability and stable power delivery. Equipped with a native 12V-2x6 (600W) connector, the NZXT C1000 Gold ATX 3.1 is ready for NVIDIA GeForce RTX 40 Series cards and upcoming models. Its 1000W capacity and fully modular cabling allow optimal airflow inside the case, suiting high-end gaming PCs and creative workstations alike.

Compatibility Guide

Form factor: standard ATX (150 x 86 x 160 mm) – fits most ATX/Micro-ATX/E-ATX cases with at least 160mm depth for the PSU. Connectors include: 24-pin ATX, dual 4+4-pin EPS12V (CPU), 6+2-pin PCIe, native 12V-2x6 (600W) for modern GPUs, plus SATA and peripheral cables. For older GPUs (RTX 30 series or earlier), use the included standard PCIe cables – do not attempt to reuse any legacy 12VHPWR cable with the 12V-2x6 port. The 1000W rating provides ample headroom for a Ryzen 9 / Core i9 + RTX 4090 combo, plus drives and peripherals.

Product Info

Released in 2024, the NZXT C1000 Gold ATX 3.1 sits in the mid-to-high tier Gold-efficient PSU market. Key specs: 1000W continuous output, 80 Plus Gold / Cybenetics Gold efficiency, Cybenetics A noise rating (max ~28 dBA), 135mm dynamic fan with zero-fan mode up to 50% load, 100% Japanese capacitors, full modular cabling. Reference price in Japan is ¥27,665 (via). Warranty: 10 years.

Best Use Cases

High-end gaming PC builds: Pairing an RTX 4080/4090 with an i7/Ryzen 7 or higher? This PSU delivers stable power and direct 12V-2x6 connection for future upgrades. 1000W leaves room for overclocking. Silent-focused creative workstations: Zero-fan mode keeps the system inaudible during idle/light loads. Under heavy rendering or video encoding, the Cybenetics A-rated fan remains quiet, ideal for noise-sensitive environments. * Clean, well-managed builds: Fully modular cables and compact 160mm depth simplify cable routing. No unused pigtails cluttering the case, improving airflow and aesthetics.

Things to Consider

This PSU is ATX 3.1 compliant – note the new 12V-2x6 connector is physically different from the older 12VHPWR. Do not attempt to use a legacy 12VHPWR cable on this unit; use the provided native cable or an approved adapter (though adapters are not recommended). For mainstream gaming PCs with an RTX 4070 class or lower GPU, 1000W is overkill – a 750W or 850W model would suffice and save money. Competitors in the same price/performance bracket include the Seasonic Focus GX-1000 (ATX 3.0) and Corsair RM1000e – compare warranty (all 10 years) and fan noise preferences. Also, because it's fully modular, keep the included cable pack safe; replacement cables must be NZXT-specific.
