750 W ATX12V supply for desktop builds

The NZXT C750 is a 750 W ATX12V v2.4 power supply with a single +12 V rail and 80 PLUS BRONZE certification. Its semi-modular design keeps the 24 pin ATX cable fixed while letting you attach only the EPS, PCIe, SATA and peripheral leads you need. A 120 mm FDB fan handles cooling, and the unit carries a >100,000 hour MTBF rating.

Check case depth and cable routing before ordering

The PSU measures 140 mm in maximum length, so confirm your chassis can accommodate that dimension. You will receive three 6+2 pin PCIe cables and two 4+4 pin EPS cables in the box; verify that quantity matches the graphics card and CPU power requirements of your build. Input voltage covers 115 / 230 V at 47 - 63 Hz for worldwide mains compatibility.

Black finish with fixed 24 pin and detachable

The black housing uses a semi-modular layout: the 24 pin motherboard cable is permanently attached, while six SATA, three 4 pin peripheral and the PCIe or EPS cables connect only when required. Six 6+2 pin PCIe connectors support multi GPU configurations, and the 550 mm ATX cable length suits standard mid tower routing. Four 6-32 mounting screws are included for installation.

Questions about this item

Which cables come with the C750 and what must I source separately?

The box includes the 24-pin ATX cable, two 4+4-pin CPU cables, three 6+2-pin PCIe cables, two SATA cables and a peripherals cable. You will need extra PCIe or SATA cables if your build uses more than three graphics power plugs or more than two SATA drives.

How do I decide between the available capacities for this series?

This listing is the 750 W model; choose it when your total system draw under load sits below 750 W and you want the 80 PLUS BRONZE efficiency rating.

What does the 750 W rating mean once the unit is installed in my PC?

It means the PSU can continuously deliver up to 750 W across its single +12 V rail, with the 120 mm FDB fan spinning only as needed to keep temperatures in check.
