Overview

The NZXT C1000 Gold ATX 3.1 Power Supply is a fully modular 1000-watt unit engineered for high-performance PC builds that demand stable, efficient power delivery. Built to the ATX 3.1 standard, it provides robust protection against the transient power spikes that modern CPUs and GPUs can generate during intensive workloads. The native 12V-2x6 connector supports up to 600 watts of direct power delivery to NVIDIA GeForce RTX 40 Series graphics cards, eliminating the need for adapter cables and the potential reliability concerns that come with them. With 80 PLUS Gold and Cybenetics Gold efficiency certifications, the C1000 converts AC power to DC with minimal waste, keeping electricity costs down and heat output manageable even under sustained gaming or rendering loads.

Inside, 100% Japanese capacitors handle the critical task of smoothing power output, improving hold-up time during brief power interruptions, and minimizing ripple noise that can affect sensitive components. The 135mm fluid dynamic bearing fan operates in Zero Fan Mode when the PSU draws less than 50% of its rated load, meaning the unit is completely silent during everyday tasks, web browsing, and lighter gaming sessions. When the fan does engage under heavy loads, it maintains a Cybenetics A noise rating — among the quietest classifications available. The fully modular cable system means you connect only what your build requires, keeping your case interior clean and airflow unobstructed. Finished in white with a clean, modern design, the C1000 Gold is built to be both a reliable workhorse and a visual complement to white-themed or showcase builds.

Pros & Cons

👍 Pros

  • 1000-watt capacity with 80 PLUS Gold efficiency minimizes wasted energy and heat output during sustained loads.
  • ATX 3.1 compliance with native 12V-2x6 connector delivers stable, spike-resistant power to current-generation GPUs.
  • Zero Fan Mode keeps the PSU completely silent below 50% load, ideal for quiet builds and low-demand tasks.
  • 100% Japanese capacitors enhance power stability, hold-up time, and long-term reliability.
  • Fully modular cable design lets you install only the cables you need, reducing clutter and improving case airflow.

👎 Cons

  • 1000-watt capacity may be more than necessary for mid-range builds, adding cost without practical benefit for lower-power systems.
  • White color option may not match all case interiors, and white cables can show dust and discoloration over time.
  • At 1000 watts, the physical unit is larger and heavier than lower-wattage PSUs, which may be tight in compact cases.
  • Does not include individually sleeved cables — custom cables must be purchased separately for a premium aesthetic.

Frequently Asked Questions

Yes, it includes a 12V-2x6 connector rated for up to 600 watts, which meets the power delivery requirements for NVIDIA GeForce RTX 40 Series GPUs.
The 135mm fluid dynamic bearing fan operates in Zero Fan Mode when the PSU is under 50% load (500W or less), making it completely silent during light to moderate use. Under heavier loads, the fan spins up but remains quiet with a Cybenetics A noise rating.
Fully modular means every cable — including the main 24-pin ATX cable — detaches from the unit. You only connect the cables you need, which reduces clutter and improves airflow inside your case.
Yes, ATX 3.1 provides improved power spike resistance and stability for all components, not just GPUs. It ensures your PSU can handle transient power spikes that modern processors and graphics cards may produce.
