NZXT C750 Gold Core ATX 3.1 power supply

The NZXT C750 Gold Core is a fully modular ATX 3.1 power supply rated for 750 W. It targets builders who want efficient, quiet power for modern graphics cards and CPUs. The unit carries 80 PLUS Gold and Cybenetics Platinum efficiency certifications. A 135 mm fluid dynamic bearing fan with Zero RPM mode keeps noise low during light workloads.

750 W capacity and PCIe 5.1 headroom

A single +12 V rail delivers the full 750 W to high-demand components. The supply includes a native 12V-2x6 connector for PCIe 5.1 graphics cards plus two 6+2-pin PCIe cables for older GPUs. Eight SATA power connectors handle drives and peripherals. Efficiency reaches 89.53 percent at 115 V input under full load, reducing waste heat when the system is pushed hard.

150 mm fully modular build with premium protections

The compact 150 mm length fits a wide range of cases while the fully modular design lets you install only the cables you need. Embossed cables simplify routing and improve airflow. Protections include OVP, UVP, SCP, OTP, OPP and OCP. A 105 °C-rated capacitor bank and Cybenetics A++ noise rating ensure stable, quiet operation across the 100 to 240 V input range.

Questions about this item

Will the ATX 3.1 design and 150 mm length fit my older case that only takes standard ATX supplies?

The unit follows the ATX 3.1 form factor and measures 150 mm long, matching the depth of most standard ATX cases; verify your chassis clearance before installing.

How can I confirm the 12V-2x6 connector is seated correctly on my new GPU?

The 12V-2x6 cable uses dual-color housing that shows a visible contrast when the plug is fully inserted, giving a quick visual check after installation.

Which cables are included and will I need extra 8-pin PCIe leads for a three-connector card?

The box supplies the 24-pin motherboard cable, one 12V-2x6 connector, two 6+2-pin PCIe cables, and eight SATA power connectors; a third 8-pin PCIe cable would need to be sourced separately.
