The NZXT C1200 is built on a foundation of premium components and advanced design principles, ensuring it provides a consistent and robust electrical signal to all of your hardware.

ATX 3.1 and the 12V-2×6 Connector: The New Standard

The most significant feature of the NZXT C1200 is its compliance with the Intel ATX 3.1 standard. This is a crucial evolution over the previous ATX 3.0, and it directly addresses the challenges presented by modern, high-power GPUs.

The core of this standard is the new 12V-2×6 connector, which replaces the older 12VHPWR connector. The 12V-2×6 connector features a refined design with longer power pins and shorter sideband pins. This seemingly minor change has a major impact: it ensures the power connection is fully seated before the GPU can draw its full power, effectively preventing the overheating and melting issues that were associated with partially inserted cables.

The NZXT C1200 comes with a single, high-quality native 12V-2×6 cable that can deliver up to 600W to a single graphics card. This means you can power even the most demanding flagship GPUs without using a multi-cable adapter, resulting in a cleaner, more reliable, and aesthetically pleasing build.

The PSU is also rated to handle transient power spikes of up to 200% of its rated wattage, a key requirement of the ATX 3.1 specification that ensures your system remains stable even during sudden, intense load changes in games or creative applications.

1200W of Clean Power: A Single-Rail Design

With a total output of 1200 watts, the NZXT C1200 is more than capable of powering high-end systems. Its design is centered around a single, powerful +12V rail capable of delivering 100A. A single-rail design is inherently more flexible and reliable than a multi-rail design, as it allows your components to draw power as needed without worrying about the load on a specific rail.

This immense power capacity means you can confidently run a flagship CPU, such as an Intel Core i9 or AMD Ryzen 9, paired with a top-tier GPU, multiple storage drives, and a full suite of peripherals without coming close to its limits. This power headroom is not only for maximum performance today but also provides ample capacity for future upgrades.

80 PLUS Gold and Beyond: Unmatched Efficiency

The NZXT C1200 boasts an 80 PLUS Gold certification, a testament to its exceptional efficiency. This certification guarantees that the PSU will operate at a minimum of 87% efficiency under a 20% load, 90% at 50% load, and 87% at full load.

In practice, the NZXT C1200 often exceeds these minimum requirements, providing a higher level of efficiency that translates to several tangible benefits. More of the electricity drawn from the wall is converted into usable power for your components, which reduces wasted energy as heat. This not only lowers your electricity bill over time but also contributes to a cooler internal case temperature, benefiting all of your components. The lower heat generation also directly contributes to quieter operation.

The use of these top-tier capacitors ensures that the NZXT C1200 delivers an incredibly clean and stable power signal, providing a reliable and long-lasting foundation for your build, backed by an impressive 10-year warranty.

The Silence of Performance: Fluid Dynamic Bearing Fan

A powerful PC doesn’t have to be a loud one. The NZXT C1200 is equipped with a 135mm Fluid Dynamic Bearing (FDB) fan, a key feature for both performance and acoustics.

FDB fans use a thin layer of fluid as a lubricant, which significantly reduces friction and wear compared to traditional sleeve or ball bearings. This results in an exceptionally quiet fan that also has a longer lifespan.

The PSU’s fan features a Zero RPM mode, which means the fan won’t spin at all when the power supply is under 50% load. This allows for completely silent operation during light tasks like web Browse, video streaming, or word processing.

When the load increases during intense gaming or rendering, the fan intelligently ramps up to provide the necessary cooling, but it does so while maintaining a low noise profile, ensuring your PC remains as quiet as possible.

Complete Protection Suite: Safeguarding Your System

The NZXT C1200 is designed with a comprehensive suite of safety protections to guard your valuable components against any electrical irregularities. This includes:

• OVP (Over Voltage Protection): Protects against a sudden surge in voltage on any rail.
• UVP (Under Voltage Protection): Shuts down the PSU if the voltage drops below a safe level.
• OPP (Over Power Protection): Prevents damage from a total power draw that exceeds the PSU’s capacity.
• SCP (Short Circuit Protection): Instantly shuts down the unit if a short circuit is detected.
