NZXT C1200 Gold ATX 3.1 Fully Modular Low-Noise PC Gaming Power Supply (White)

The NZXT C1200 Gold (PA-2G2BW-UK) is a 1200-watt, 80 Plus Gold certified, fully modular power supply built to the ATX12V v3.1 and EPS12V v2.92 standards. Its white finish suits white-themed builds, while its compact 150 mm × 86 mm × 160 mm steel chassis keeps the footprint small enough to leave generous room for cable routing in most mid- and full-tower cases. At the heart of the C1200 Gold is a 135 mm fluid dynamic bearing (FDB) fan that operates in Zero Fan Mode — remaining completely stationary below 50% load — so the unit runs silently during everyday tasks. Under full load the fan spins to a maximum of 2,300 RPM (±10%) and moves at least 93.02 CFM of air, keeping internal temperatures in check within a 0–50 °C operating range. Rated noise ceiling is 44.5 dBA, measured at maximum speed. Power delivery is anchored by a single +12V rail rated at 100 A (1,200 W). The unit includes a native 16-pin (12+4) 12V-2x6 connector rated for up to 600 W, designed for compatibility with NVIDIA GeForce RTX 40 Series graphics cards. Active Power Factor Correction holds PF at 0.99, and six independent protection circuits — OVP, UVP, SCP, OTP, OPP, and OCP — guard connected components against electrical faults. The fully modular cable system ships with: one 24-pin ATX cable (600 mm, nylon sleeved), one 4+4-pin CPU cable (700 mm), one 8-pin CPU cable (700 mm), three 6+2-pin PCIe cables (650 mm each), one 16-pin 12V-2x6 cable (650 mm), twelve SATA connectors, and four peripheral (4-pin) connectors. Every cable uses nylon sleeving on the CPU and PCIe runs for a cleaner finish. Efficiency at 115 Vac is rated at 85% at 10% load, 90.1% at 20% load, 91.6% at 50% load, and 88.7% at full load — meeting 80 Plus Gold thresholds across the range. The unit carries a wide range of regulatory certifications including FCC, CE, UKCA, CB (IEC 62368-1), TUV, cTUVus, CCC, BSMI, BIS, RCM, KC, UAE, and CP65. MTBF is rated at 100,000 hours. NZXT backs the C1200 Gold with a 10-year warranty.
