NZXT C1200 1200W 80 + Gold Fully Modular ATX 3.1 Power Supply ( White )

The NZXT C1200 is a 1200-watt fully modular power supply built to the ATX 3.1 standard, designed to deliver stable, efficient power to demanding PC components including high-end CPUs and the latest discrete graphics cards. Its compliance with ATX12V v3.1 and EPS12V v2.92 means it is engineered to handle the transient power spikes that modern GPUs can produce, reducing the risk of unexpected shutdowns during intensive workloads or gaming sessions. At the heart of the C1200’s cable ecosystem is a single 16-pin (12+4) 12V-2×6 connector capable of delivering up to 600 W to compatible graphics cards such as the NVIDIA GeForce RTX 40 Series. Three additional 6+2-pin PCIe cables, one 4+4-pin CPU cable, one 8-pin CPU cable, and a 24-pin ATX mainboard cable complete the modular cable set — all finished with nylon sleeving for a clean, professional build aesthetic. The fully modular design means only the cables you need attach to the unit, keeping your chassis tidy and improving internal airflow. Thermal management is handled by a 135 mm fluid dynamic bearing (FDB) fan rated to 2,300 ±10% RPM, delivering a minimum airflow of 93.02 CFM. Zero Fan Mode keeps the fan completely off when system load stays below approximately 50%, resulting in passive, silent operation during light tasks or idle. At peak the fan reaches a maximum of 44.5 dBA. Energy efficiency is certified at 80 Plus Gold, with measured efficiencies of 85% at 10% load, 90.1% at 20% load, 91.6% at 50% load, and 88.7% at full load (all at 115 Vac). Active power-factor correction reaches 0.99, minimising wasted reactive power. The unit’s 12 V rail is rated at 100 A (1,200 W), while the combined 3.3 V/5 V rails are rated at 22 A (120 W combined) and the 5 Vsb standby rail at 3 A (15 W). Protection circuits cover overvoltage (OVP), undervoltage (UVP), short circuit (SCP), over-temperature (OTP), overpower (OPP), and overcurrent (OCP). The unit carries a mean time between failures (MTBF) rating of 100,000 hours and an operating temperature range of 0–50 °C. Certifications include FCC, CE, CB (IEC 62368-1), UKCA, TUV, cTUVus, CCC, BSMI, BIS, RCM, UAE, KC, and CP65.
