Overview

The NZXT C1000 Gold ATX 3.1 is a fully modular 1000W power supply with 80 PLUS GOLD certification. It supports the latest ATX 3.1 standard and features a native 12V-2x6 connector designed for NVIDIA GeForce RTX 40 series graphics cards. A 135mm fluid dynamic bearing fan with zero fan mode ensures silent operation at low loads. The unit uses 100% Japanese capacitors for enhanced reliability and stable power delivery. This PSU is positioned as a mid-high range solution for high-end gaming PCs and creator workstations.

Compatibility Guide

The C1000 Gold ATX 3.1 uses the standard ATX form factor, fitting most ATX-compatible PC cases. The native 12V-2x6 connector supports RTX 40 series GPUs up to 600W without adapters. There are no special CPU or motherboard restrictions—it works with both Intel and AMD platforms. All necessary cables are included, and the fully modular design lets you use only the cables you need.

Product Info

Released in late 2024, the C1000 Gold ATX 3.1 is available through major retailers like Japan, typically priced around ¥27,000–¥28,000. NZXT backs it with a 10-year warranty. The 135mm FDB fan enables zero fan mode (fan stops below 50% load). Japanese capacitors reduce ripple and improve hold-up time. Its market position is mid-high tier, targeting users who demand both performance and silence.

Best Use Cases

High-end gaming builds: With native 12V-2x6 for RTX 4080/4090, cable management is clean and power delivery is reliable. Silent PC enthusiasts: Zero fan mode and quality FDB fan keep noise to a minimum during idle or light loads. * Creative workstations: 1000W headroom and robust capacitor design ensure stability during long rendering or heavy compute tasks.

Things to Consider

If upgrading from an older ATX 2.x PSU, note that all cables are proprietary—use only the included set. 1000W is overkill for mid-range gaming PCs (e.g., RTX 4070); a 750W–850W unit may be more cost-effective. The zero fan mode can lead to higher internal case temperatures if airflow is poor—ensure your case has adequate ventilation. Competitors include Corsair RM1000x and Seasonic Focus GX-1000; compare pricing and warranty terms before buying.
