NZXT C1200 ATX 3.0 - 1200 Watt 80 Plus Gold Fully Modular SMPS

The NZXT C1200 is a 1200-watt, fully modular power supply built to the ATX 3.0 standard, carrying an 80 Plus Gold efficiency certification. It is designed for demanding desktop PC builds — particularly those pairing a high-end processor with a power-hungry discrete graphics card — where headroom, clean delivery, and cable management all matter. The defining connectivity feature of the C1200 is its 16-pin PCIe 12VHPWR connector, which can deliver up to 600 watts of power to a compatible graphics card over a single cable. This eliminates the need to daisy-chain multiple 8-pin cables to next-generation GPUs and reduces clutter inside the chassis. The ATX 3.0 specification also introduces tighter transient load tolerance requirements, helping protect components during sudden spikes in GPU power draw — a real-world concern with modern graphics cards. Full modularity means every cable — including the 24-pin ATX motherboard cable — detaches completely from the PSU housing. Builders can install only the cables their system actually requires, improving airflow and making routing behind the motherboard tray significantly easier. The 80 Plus Gold rating indicates that the unit meets efficiency targets of at least 87% at 20% load, 90% at 50% load, and 87% at 100% load (tested at 115 V AC), reducing wasted heat output and keeping operating costs lower over the life of the unit compared to lower-rated alternatives.
