850W 80 Plus Gold Fully Modular Power Supply

Exceptional Power for Demanding Systems:

The NZXT C850M 80 Plus Gold Power Supply delivers a powerful 850 watts of stable and efficient energy, making it a perfect choice for gamers, creators, and PC enthusiasts who demand top-tier performance. Whether you are running a high-end gaming setup, a workstation with multiple GPUs, or planning an SLI or Crossfire configuration, this PSU ensures consistent and reliable power delivery under any load. With its 80 Plus Gold certification, the C850M guarantees high energy efficiency, keeping your system running smoothly while minimizing wasted power.

Fully Modular and Builder-Friendly Design:

The C850M features a fully modular cable management system that allows builders to use only the cables they need, creating a clean and clutter-free build. This not only improves airflow inside the case but also makes installation and future upgrades much easier. The high-quality nylon-sleeved cables resist heat damage and fraying, ensuring long-term durability and a sleek, professional appearance. Whether you’re building a compact setup or a large tower, this PSU fits seamlessly in any ATX-standard case.

Optimized Cooling and Whisper-Quiet Performance:

Noise is minimized thanks to the PSU’s Zero RPM Fan Mode, which stops the fan entirely under low-load conditions, providing silent operation during light tasks. When additional cooling is required, the dynamic 135mm Fluid Dynamic Bearing (FDB) fan automatically adjusts its speed to maintain optimal airflow and temperature control. With a maximum airflow of 93.02 CFM and noise levels up to just 44.5 dBA, this fan design ensures quiet yet effective cooling even during intense gaming or rendering sessions.

Stable and Reliable Power Output:

The NZXT C850M is engineered to deliver stable voltage and efficient power distribution across all components. It supports a single +12V rail with 70.8A output (850W) for high-performance GPUs and CPUs, along with balanced power on the +3.3V and +5V rails. With an Active Power Factor Correction (PFC) of 0.96 and an MTBF (Mean Time Between Failures) of 100,000 hours, this PSU offers exceptional reliability and long-term performance. It also maintains efficiency across various loads — reaching up to 90.8% efficiency at 50% load.

Comprehensive Connectivity for Modern Builds:

Designed to support the latest PC components, the C850M includes a generous array of connectors. Builders have access to two 4+4-pin CPU power connectors, six 6+2-pin PCIe connectors for powerful graphics cards, six SATA connectors for storage devices, and six peripheral connectors for additional accessories. The cables come in varying lengths — from 500 mm to 700 mm — allowing flexibility for any case layout and cable routing preference. Every connection is clearly labeled, making installation straightforward and secure.

Built for Compatibility and Safety:

This PSU fully complies with the ATX12V v2.52 and EPS12V v2.92 standards, ensuring broad compatibility with today’s and future-generation motherboards. It supports NVIDIA GPUs up to RTX 3090 and AMD GPUs up to RX 6900 XT, giving you the confidence to power the most demanding components. Safety and reliability are reinforced through a variety of international certifications, including TUV, CE, CCC, UKCA, and EAC, ensuring it meets strict electrical and environmental regulations for performance and protection.

Durable Construction and Premium Materials:

Built with precision and quality, the NZXT C850M combines steel, PCB, and high-grade plastic materials in a compact 150 x 150 x 86 mm frame. Its durable build quality ensures consistent operation in environments ranging from 0°C up to 50°C, with derating only from 40°C to 50°C. Every component has been selected to handle heavy workloads and extended usage, making the C850M a long-term investment for serious PC users.

Energy Efficiency You Can Trust:

As an 80 Plus Gold certified PSU, the NZXT C850M maintains outstanding energy efficiency levels: 89.7% at 20% load, 90.8% at 50% load, and 88.0% at full load. This translates to lower power consumption, reduced heat output, and a more environmentally friendly operation. The efficiency not only benefits performance but also contributes to system longevity by reducing strain on electrical components.

Premium Power, Precision, and Performance:

The NZXT C850M 80 Plus Gold Fully Modular Power Supply stands out as a premium, high-efficiency power solution for gaming PCs and workstations. With its clean modular design, exceptional cooling system, and stable power delivery, it combines elegance and reliability in one unit. Ideal for enthusiasts who value both aesthetics and performance, the C850M is built to support today’s most powerful components — and ready for tomorrow’s upgrades.
