NZXT C1000 Gold ATX 3.1 Fully Modular Low-Noise PC Gaming Power Supply (Black)

The NZXT C1000 Gold is a 1000-watt, 80 PLUS Gold certified, fully modular power supply built to the ATX 3.1 standard. Designed for high-performance gaming and workstation builds, it delivers stable, efficient power to demanding CPUs and GPUs while maintaining a notably quiet acoustic profile. The unit features a 135mm fluid dynamic bearing (FDB) fan equipped with Zero Fan Mode, which keeps the fan completely off when system load stays below 50%, resulting in silent operation during light use and everyday tasks. Under full load the fan spins at up to 2,300 RPM and moves a minimum of 93.02 CFM, with peak noise rated at 44.5 dBA. ATX 3.1 and EPS12V v2.92 compliance means the C1000 Gold is engineered to handle the transient power spikes that modern GPUs can produce. 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 the need for adapters. The fully modular cable system allows you to connect only the cables your build requires, reducing interior clutter and improving airflow. All cables use nylon sleeving for a clean, professional finish. The compact chassis (150 × 86 × 160 mm) leaves additional room for cable routing in tighter cases. Power integrity is maintained through 100% Japanese capacitors, active power factor correction (PFC rated at 0.99), and a comprehensive protection suite covering overvoltage (OVP), undervoltage (UVP), short circuit (SCP), over temperature (OTP), overpower (OPP), and overcurrent (OCP). The unit carries an MTBF rating of 100,000 hours and is backed by a 10-year warranty from NZXT.
