Nzxt C850 Gold Fully Modular ATX 3.1 White SMPS

The NZXT C850 Gold is an 850-watt, fully modular ATX 3.1 power supply finished in white — a practical choice for builders who want clean aesthetics alongside reliable, high-efficiency power delivery. Certified 80 Plus Gold, it is engineered to meet the demanding power requirements of modern high-performance CPUs and the latest discrete graphics cards. ATX 3.1 compliance means the unit is ready for next-generation platforms, offering improved transient power handling and stable delivery under rapidly fluctuating loads — a key concern with contemporary GPU architectures. The included 12V-2x6 connector is rated to deliver up to 600 watts, making it compatible with NVIDIA GeForce RTX 50 Series graphics cards out of the box. Cooling is handled by a 135mm fluid dynamic bearing (FDB) fan paired with NZXT's Zero Fan Mode. Under 50% load the fan stops spinning entirely, producing no audible noise — ideal for productivity workloads, light gaming, or any scenario where silence matters. When the load climbs, the fan ramps up smoothly thanks to the fluid dynamic bearing design, which also contributes to long-term durability. Internally, the C850 Gold uses 100% Japanese capacitors, chosen for their improved hold-up time and reduced ripple noise characteristics, supporting stable voltage delivery across all rails even under sustained load. The fully modular cable system means only the cables you actually need connect to the unit, reducing clutter inside the chassis and improving airflow around components. The compact form factor further aids cable routing and leaves more room in tight mid-tower or small-form-factor builds. NZXT backs this unit with a 10-year warranty. **Verified Specifications** - Model: NZXT C850 Gold (PA-8G2BW-UK/AU) - Wattage: 850 W - Efficiency Rating: 80 Plus Gold - Standard: ATX 3.1 - Modular: Fully Modular - Fan: 135 mm Fluid Dynamic Bearing with Zero Fan Mode - GPU Connector: 12V-2x6 (up to 600 W) - PCIe Connectors (6+2-pin): 3 - SATA Connectors: 12 - Peripheral (4-pin) Connectors: 4 - Capacitors: 100% Japanese - Colour: White - Warranty: 10 Years
