750 W ATX power supply for gaming PCs

This NZXT C750 unit delivers up to 750 W of continuous power through a fully modular cable set. It carries 80 PLUS Gold certification for high efficiency and uses a 135 mm fan for quieter operation. The 150 mm length fits most standard ATX cases.

Check ATX compatibility and connector needs

Verify your motherboard accepts a 24-pin main connector and that your graphics card can use the six 6+2-pin PCIe leads. Ensure the case has room for a 150 mm deep ATX unit and that you have drive bays or mounts for up to six SATA power connections.

Fully modular design frees cable space

Only the cables you need stay inside the chassis, reducing clutter and improving airflow around the GPU and CPU cooler. The single 135 mm fan handles thermal load while the Gold-rated efficiency lowers waste heat, leaving more headroom for overclocked components.

Questions about this item

Does the box include every cable I need or are any sold separately?

The unit is fully modular and ships with a US power cord, a 24-pin motherboard cable, six 6+2-pin PCIe cables and six SATA power cables.

How do I decide whether the 750 W model is the right capacity for my build?

Choose this 750 W version if your total system draw under load stays below that figure; it leaves headroom for a mid-range GPU and CPU while keeping efficiency in the Gold band.

What does the 80 PLUS Gold rating actually deliver inside my PC?

It guarantees at least 80 % efficiency at typical loads, which means less waste heat and quieter fan operation from the 135 mm fan during everyday use.
