This article covers NZXT C1000 PC電源ユニット 1000W 80PLUS Gold.

Overview

The NZXT C1000 Power Supply delivers 1000W of continuous power with 80 PLUS Gold certification, making it a reliable choice for mid-to-high-end PC builds. Its fully modular design lets you attach only the cables you need, simplifying cable management and improving airflow inside the case. A 135mm fluid-dynamic-bearing (FDB) fan ensures quiet operation even under heavy loads, and the unit is backed by an industry-leading 10-year warranty. The C1000 strikes a solid balance between performance, noise, and longevity, appealing to gamers, creators, and PC enthusiasts alike.

Compatibility Guide

This PSU adheres to the standard ATX form factor, so it fits in any case designed for ATX power supplies. It includes a 24-pin ATX main connector, two 8-pin EPS12V CPU connectors, and multiple PCIe 6+2-pin connectors for graphics cards. Before purchasing, verify that your case has enough depth (typically 150mm or more) to accommodate the unit, especially in compact MicroATX or Mini-ITX cases. The unit works with all modern motherboards supporting ATX or EPS power delivery.

Product Info

The NZXT C1000 (model PA-0G1BB-JP) launched in 2022 and is sold in Japan as an officially authorized product. It carries 80 PLUS Gold efficiency (87-90% typical load) to reduce electricity costs and heat output. The fully modular black sleeved cables complement the matte-black chassis for a clean build aesthetic. An internal MCU monitors voltage, current, and output power, protecting against overcurrent, overvoltage, and short circuits. This PSU sits in the mid-high tier, suited for gaming PCs and creator workstations that demand stable, clean power.

Best Use Cases

High-end gaming PCs: With 1000W capacity, it easily powers flagship GPUs like RTX 4080 or RX 7900 XTX and overclocked CPUs. The fully modular design simplifies routing in mid-tower and full-tower cases. Silent builds: The 135mm FDB fan uses PWM control and has noise-dampening adhesives on components, keeping the unit nearly inaudible at low loads. Ideal for home offices or media centers where silence is paramount. * Long-term systems: The 10-year warranty allows you to carry the PSU across multiple builds, reducing long-term cost. It's a smart choice for users who upgrade every few years but want a power supply that lasts.

Things to Consider

For a typical mid-range gaming PC (e.g., Core i5 + RTX 3060), 1000W is overkill; a 650W-750W unit would be more cost-effective. Also, the C1000 is ATX only, so it won't fit in small-form-factor cases requiring SFX power supplies. Competitors like the Seasonic Focus GX-1000 or Corsair RM1000x offer similar specs, sometimes with better internal components, but the NZXT unit is generally more affordable during sales. Note that the C1000 does not include a native 12VHPWR cable for RTX 40-series GPUs; you may need an adapter or separate cable. Overall, it's a dependable power supply that suits those who prioritize quiet operation and modular cable management.
