Nzxt C850 850W Gold Fully Modular ATX 3.1 Power Supply - Black

The NZXT C850 is an 850-watt, fully modular ATX power supply designed for enthusiast and gaming PC builds that demand stable, efficient, and future-ready power delivery. Built to the ATX 3.1 standard, it is engineered to handle the transient power spikes associated with the latest high-performance graphics cards and processors, reducing the risk of unexpected shutdowns during intensive workloads or gaming sessions. The fully modular cable design means every cable — including the motherboard and CPU connectors — can be removed when not in use. This allows for cleaner cable routing inside your chassis, better airflow, and a tidier finished build without the clutter of unused leads. The C850 carries the 80 Plus Gold efficiency certification, which independently verifies that the unit operates at 87–92% efficiency across typical load ranges. Higher efficiency translates directly into less energy wasted as heat, lower operating temperatures inside your case, and reduced electricity consumption over time. Compliance with ATX 3.1 means the C850 meets the latest Intel power-supply specification, including support for the 12V-2x6 connector and improved transient-load handling required by current PCIe 5.0 graphics cards. This makes it a forward-compatible choice for present and near-future platform upgrades. NZXT backs the C850 with a 10-year warranty, reflecting confidence in the unit's long-term reliability. The black finish integrates cleanly into dark-themed builds.
