SKU : PS-NZXT C750 BLACK BRONZE
Wattage: 750 W
Efficiency: 80 PLUS Bronze
Form Factor: ATX 3.1
Dimensions (W x H x D): 150 x 86 x 140 mm
GPU Power: 1x 16-pin 12V-2x6, 2x 8-pin (6+2) PCIe
Cabling: Non-modular
Cooling: 120 mm fan

The NZXT C750 Bronze (Model: PA-7B3BB-UK) brings reliable, future-proof power to entry-level and mid-range PC builds. Compliant with the new ATX 3.1 standard, this 750-watt unit handles power excursions and transient spikes better than older ATX 2.4 models, providing a rock-solid foundation for today's demanding hardware.
Expanded Key Features
ATX 3.1 & PCIe Gen 5.1 Ready: Eliminates the need for bulky GPU adapter cables. Includes a native 12V-2x6 connector capable of delivering clean, stable power directly to the latest high-end graphics cards, ensuring maximum safety and performance.
80 PLUS Bronze Certified Efficiency: Operates at over 88% efficiency at 50% load. This reduces power consumption, lowers your electricity bill, and generates less ambient heat inside your system.
Premium 105°C Capacitors: Built with high-quality 105°C-rated bulk capacitors that offer superior endurance and reliability compared to standard 85°C components, delivering consistent power output even in environments up to 40°C.
Quiet 120mm FDB Fan Cooling: Keeps acoustics low without sacrificing airflow. The 120mm fluid dynamic bearing (FDB) fan spins whisper-quiet under normal loads and ramps up smoothly when the system demands heavy power, extending the lifespan of the PSU.
Compact 140mm Footprint & Flat Cables: The shallow 140mm depth guarantees excellent clearance for hard drive cages and thick front radiators. The non-modular design utilizes stealthy, flat black cables and nylon-sleeved main cables to seamlessly blend into your build and simplify cable routing.
Comprehensive Protection Suite: Equipped with a full range of heavy-duty safeguards, including Over-Voltage Protection (OVP), Under-Voltage Protection (UVP), Over-Current Protection (OCP), Over-Temperature Protection (OTP), and Short-Circuit Protection (SCP).
Why This Product Stands Out
The NZXT C750 Bronze stands out by bringing flagship-tier ATX 3.1 safety standards and native 12V-2x6 GPU connectivity to a budget-friendly 80 PLUS Bronze price point. It is the perfect drop-in power solution for builders constructing a modern RTX 40-series gaming PC without the premium cost of a fully modular ATX 3.0/3.1 unit.
