NZXT C850 850W 80 + Gold Fully Modular ATX 3.1 Power Supply (White)

The NZXT C850 850W 80 Plus Gold Fully Modular ATX 3.1 Power Supply in White is engineered for high-performance PC builds that demand stable, efficient power delivery. Compliant with the ATX12V v3.1 and EPS12V v2.92 standards, it is well-suited for systems pairing modern CPUs with power-hungry discrete graphics cards. At the heart of its GPU compatibility is the included 16-pin (12+4) 12V-2x6 PCIe cable, rated to deliver up to 600 watts to NVIDIA GeForce RTX 40 Series graphics cards. Three additional 6+2-pin PCIe cables further expand multi-GPU and peripheral flexibility. All cables feature nylon sleeving for a clean, tidy build aesthetic. The 135mm fan uses a Fluid Dynamic Bearing (FDB) for long-lasting, low-friction operation. Zero Fan Mode keeps the unit completely passive below 50% load, allowing for a silent computing environment during light workloads. At maximum speed the fan reaches 2,300 RPM (±10%), moving a minimum of 93.02 CFM of airflow, with noise peaking at 44.5 dBA under full load. The fully modular cable system means only the cables you need connect to the unit, reducing internal clutter and promoting better case airflow. The compact 150 × 86 × 160 mm steel-and-PCB chassis leaves additional room for cable routing inside the case. Electrical protection features include Overvoltage (OVP), Undervoltage (UVP), Short Circuit (SCP), Over Temperature (OTP), Overpower (OPP), and Overcurrent (OCP) protection. Active Power Factor Correction achieves 0.99 PF, and 100% Japanese capacitors are used throughout for reliable hold-up time and low ripple noise. The unit is rated for operation from 0°C to 50°C with an MTBF of 100,000 hours.
