NZXT C1000 1000W 80 + Gold Fully Modular ATX 3.1 Power Supply ( White )

The NZXT C1000 is a 1000-watt, 80 Plus Gold certified, fully modular power supply built to the ATX 3.1 standard (ATX12V v3.1 / EPS12V v2.92). It is designed to deliver stable, efficient power to high-performance desktop PC builds, including systems running the latest generation of graphics cards and CPUs. At the heart of the C1000's GPU compatibility is its 16-pin (12+4) 12V-2x6 PCIe cable, which can supply up to 600 watts to a single graphics card. Three additional 6+2-pin PCIe cables are also included, offering flexibility for multi-GPU configurations or older cards. The fully modular cable system means you only connect the cables your build requires, keeping the interior tidy and promoting better airflow. The 135mm fluid dynamic bearing (FDB) fan regulates noise carefully. In Zero Fan Mode, the fan remains completely off when system load stays below 50%, resulting in a completely silent PSU during everyday tasks and light gaming. Under full load the fan spins up to 2,300 RPM (±10%) with a maximum noise level of 44.5 dBA and an airflow rating of 93.02 CFM minimum. Power delivery is reinforced by 100% Japanese capacitors, contributing to stable voltage rails and minimal ripple. Active power factor correction reaches 0.99 PF. A comprehensive suite of built-in protections — OVP, UVP, SCP, OTP, OPP, and OCP — guards connected components against electrical faults. Operating temperature range is 0–50°C with an MTBF of 100,000 hours. The white colour variant carries part number PA-0G2BW-UK and fits standard ATX cases at 150 mm wide × 86 mm tall × 160 mm deep. Cables are nylon-sleeved throughout: the 24-pin ATX cable measures 600 mm, both CPU cables reach 700 mm, and PCIe cables extend to 650 mm. The unit ships with 12 SATA connectors and 4 peripheral connectors.
