NZXT NZXT C1200 Gold ATX 3.1 Fully Modular Power Supply

Name: NZXT NZXT C1200 Gold ATX 3.1 Fully Modular Power Supply
Brand: NZXT
SKU: NZXT C1200 Gold

Overview

The NZXT C1200 Gold is a fully modular 1200-watt power supply built to the ATX 3.1 standard, making it ready for the demands of modern high-performance PCs. ATX 3.1 compliance means it's engineered to handle the transient power spikes that current and next-generation GPUs produce, delivering stable voltage without tripping protections. The included 12V-2x6 connector can supply up to 600 watts directly to NVIDIA GeForce RTX 40 Series graphics cards, and the fully modular design ensures you only route the cables your build actually needs.

Efficiency and acoustics are central to the C1200 Gold's design. It carries 80 PLUS Gold certification alongside Cybenetics Gold Efficiency and Cybenetics A Noise Level ratings, reflecting strong performance across both power delivery and quiet operation. The 135mm fluid dynamic bearing fan features Zero Fan Mode, shutting off entirely when the unit is under 50% load for completely silent operation during everyday tasks and lighter gaming sessions. Inside, 100% Japanese capacitors ensure reliable power delivery with minimal ripple noise and improved hold-up time, giving your components the clean, consistent power they need for sustained performance.

Pros & Cons

👍 Pros

ATX 3.1 compliance ensures stable power delivery during transient GPU power spikes
Fully modular design lets you use only the cables you need for cleaner cable management
Zero Fan Mode keeps the unit completely silent under 50% load
100% Japanese capacitors provide reliable, long-lasting power delivery with minimal ripple
Triple certified with 80 PLUS Gold, Cybenetics Gold Efficiency, and Cybenetics A Noise Level

👎 Cons

1200 watts is more than most mid-range builds need, making it overkill for non-enthusiast systems
80 PLUS Gold efficiency is a step below Platinum or Titanium ratings available in this wattage class
The fully modular cable set may include proprietary connectors that aren't cross-compatible with other PSU brands
At 1200W, the unit is physically larger and heavier than lower-wattage alternatives

Frequently Asked Questions

Is this power supply compatible with NVIDIA RTX 40 Series graphics cards?

Yes, it includes a 12V-2x6 connector rated for up to 600 watts, designed specifically for NVIDIA GeForce RTX 40 Series GPUs.

What does the Zero Fan Mode do?

When the power supply is under 50% load (600 watts or less), the 135mm fan stops completely, making the unit silent during light to moderate workloads.

Is this power supply fully modular?

Yes, it is fully modular, meaning you only connect the cables you need, which reduces clutter and improves airflow inside your case.

What does ATX 3.1 compliance mean for this unit?

ATX 3.1 is the latest power supply standard that ensures the unit can handle transient power spikes from modern GPUs without shutting down or tripping protections, providing stable power delivery under demanding loads.

What type of capacitors are used?

It uses 100% Japanese capacitors, which are known for their reliability, longer lifespan, and ability to maintain stable power delivery with minimal ripple noise.
