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

The NZXT C1000 is a 1000-watt fully modular power supply carrying an 80 Plus Gold efficiency certification. It is engineered for demanding gaming rigs and workstation builds that rely on power-hungry CPUs and multiple discrete graphics cards. Because every cable is detachable, you attach only what your build actually needs, keeping the interior clean and airflow unobstructed. NZXT’s Zero RPM Fan mode — activated via a dedicated button — stops the 135 mm Fluid Dynamic Bearing fan entirely under low-load conditions, eliminating fan noise when the system is idling or lightly loaded. Under full load the fan spins up to 2,300 RPM (±10 %) and moves up to 93.02 CFM of air, keeping internal temperatures in check while staying under 44.5 dBA at maximum speed. The FDB design is chosen for its long service life and consistent bearing performance over time. All primary cables use nylon sleeving. The 24-pin ATX cable measures 600 mm; the dual 4+4-pin CPU cables reach 700 mm, making them compatible with E-ATX cases where the motherboard tray sits farther from the PSU bay. Each of the six 6+2-pin PCIe cables runs 650 mm with a 150 mm daisy-chain extension, accommodating multi-GPU configurations or high-end single-card builds. The unit conforms to ATX12V v2.52 and EPS12V v2.92 standards and fits any modern ATX case with its compact 150 × 150 × 86 mm footprint. It accepts universal AC input (100–240 V, 50–60 Hz) and incorporates active Power Factor Correction rated at 0.96. Rated MTBF stands at 100,000 hours, and NZXT backs the C1000 with a 10-year warranty.
