NZXT 850W GOLD FULLY MODULAR C850 WHT

NZXT C850 Gold 850W 80 PLUS Gold Fully Modular ATX 3.1 White Power Supply

The NZXT C850 Gold is a 850W power supply designed to deliver stable, efficient power for gaming PCs, creator systems and compatible workstations. Its 80 PLUS Gold rating helps reduce wasted energy and heat, while the fully modular cable system is designed around the needs of the listed model.

ATX 3.1 and PCIe 5.1 ready support makes the unit suitable for compatible current-generation hardware. 1 x native 600W 12V-2x6 cable plus 3 x 6+2-pin PCIe cables provides graphics-card power for supported configurations, subject to the system's complete power requirement.

Stable Continuous Power

The unit provides up to 850W of continuous output. A power supply should be selected according to the complete system specification, including the processor, graphics card, storage devices, cooling hardware and expected upgrade path.

Efficiency and Reduced Heat

The 80 PLUS Gold certification describes the PSU's energy-conversion efficiency under defined test conditions. Higher efficiency can reduce the amount of electrical energy lost as heat, helping the cooling system operate more effectively.

Modern Graphics-Card Power

1 x native 600W 12V-2x6 cable plus 3 x 6+2-pin PCIe cables. Where a native 12V-2x6 or 16-pin cable is supplied, it should be inserted fully at both ends and routed without a tight bend immediately beside the connector.

Cable Management

The Fully modular design determines how the cables are connected. Only the required modular cables need to be installed, helping reduce unused cable clutter and improving access within the case.

Cooling and Noise

Cooling is provided by a 135mm fluid dynamic bearing fan with Zero RPM mode. Fan speed and acoustic output vary with temperature, input voltage and power load. Adequate ventilation around the PSU intake and exhaust remains important.

Electrical Design and Reliability

Modern high-efficiency ATX 3.1 platform. 105°C-rated performance capacitors. Over-voltage, under-voltage, over-current, over-power, over-temperature and short-circuit protection help protect the PSU and connected components from abnormal electrical conditions.

System Compatibility

The PSU uses the ATX format and measures 150 x 150 x 86mm. Before ordering, confirm the PC case supports the unit's length and cable-exit position. The motherboard, CPU and graphics-card connector requirements should also be checked against the supplied cable set.
