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

The NZXT C1000 is a 1000-watt, 80 Plus Gold certified, fully modular power supply built to the ATX 3.1 standard. It is designed for demanding desktop PC builds that pair high-core-count processors with power-hungry discrete graphics cards, delivering stable, efficient power with a compact physical footprint. At the heart of the C1000 is compliance with the ATX12V v3.1 and EPS12V v2.92 standards, which introduce improved transient power handling to cope with the large, instantaneous power spikes common with modern GPUs. The included 16-pin (12+4) 12V-2x6 cable — rated to carry up to 600 watts — connects directly to NVIDIA GeForce RTX 40 Series graphics cards without requiring a daisy-chained adapter, reducing heat build-up and connector stress. The fully modular cable harness means you attach only the cables your build actually needs, keeping the interior of your case tidy and preserving airflow. Cables are finished with nylon sleeving: the 24-pin ATX cable measures 600 mm, both CPU cables reach 700 mm, and the PCIe cables — including the 12V-2x6 — run 650 mm, giving ample routing length for large tower cases. Cooling is handled by a 135 mm fluid dynamic bearing (FDB) fan. The Zero Fan Mode feature stops the fan entirely when system load is below approximately 50 percent, producing zero acoustic output during light tasks. Under full load the fan peaks at 2,300 RPM (±10%) and moves a minimum of 93.02 CFM while producing no more than 44.5 dBA. The unit operates within a 0–50 °C ambient temperature range and carries a mean time between failures (MTBF) rating of 100,000 hours. Power delivery is underpinned by 100% Japanese capacitors, which contribute to tight voltage regulation and low ripple noise. Active power factor correction reaches 0.99. The C1000 ships with a full suite of hardware protections: overvoltage (OVP), undervoltage (UVP), short circuit (SCP), over-temperature (OTP), overpower (OPP), and overcurrent (OCP).
