NZXT C1200 1200W 80 + Gold Fully Modular ATX 3.0 Power Supply

The NZXT C1200 Gold is a 1200-watt, fully modular ATX 3.0 power supply designed for high-performance desktop builds that demand reliable, efficient, and clean power delivery. Built to the ATX12V v3.0 and EPS12V v2.92 compliance standards, it is an ideal match for modern PCIe 5.0 graphics cards, delivering up to 600W over a single 16-pin (12+4) 12VHPWR connector — eliminating the need for bulky multi-adapter setups and reducing the risk of connector-related issues. At the heart of this unit is an 80 Plus Gold efficiency rating, with over 90% efficiency at 50% load, helping to reduce wasted heat output and lower operating costs over time. The active power factor correction runs at 0.96, ensuring a clean power draw from your wall outlet. A rated MTBF of 100,000 hours and all-Japanese 105°C-rated capacitors speak to the long-term reliability NZXT targets with the C-series line. Cooling is handled by a 135mm PWM fan using a fluid dynamic bearing (FDB), running between 0 and 2,300 RPM (±10%). Zero Fan Mode disengages the fan entirely when system load stays below approximately 40%, allowing completely passive operation during light use or idle — and keeping acoustics to a minimum when the fan does spin, with a rated maximum of 44.5 dBA. Typical airflow is rated at 93.02 CFM. The fully modular cable system means only the cables your build needs are connected, reducing clutter and improving airflow. All primary cables feature nylon sleeving. The unit operates across a wide AC input range of 100–240V and a temperature range of 0–50°C (with power derated from 100% to 80% between 40°C and 50°C).
