Power Supply Unit NZXT C750 750 W

The NZXT C750 750 W power supply unit is a non-modular ATX PSU designed for desktop PCs and entry-level gaming systems. It delivers up to 750 W of continuous power, provides a 24-pin ATX motherboard connector, and meets 80 PLUS Bronze efficiency standards. The unit includes a 120 mm fluid dynamic bearing fan, nylon-sleeved main cables and a matte black finish. It supports AC input from 115–240 V at 50/60 Hz and carries common regulatory compliances for PC components.

Advantages

The C750 offers reliable DC-to-DC conversion that helps maintain stable voltages under load and supports GPUs drawing up to about 220 W. With measured efficiency up to 88% near half load, it surpasses the baseline Bronze standard for lower energy loss and reduced heat. A 120 mm fluid dynamic bearing fan provides quiet cooling and longer lifespan, while over-temperature and over-current protections add safety. Nylon-sleeved main cables improve durability and the matte black housing fits a wide range of builds.

Suitable for

• Entry-level to mid-range gaming PCs
• Systems with single mid-power GPUs (up to ~220 W)
• Home or office desktops requiring a reliable 750 W PSU
• Builds that prefer non-modular PSUs with sleeved main cables

How to use

Install the NZXT C750 into a compatible ATX case following the motherboard and case manual. Connect the 24-pin ATX cable to the motherboard and attach the required PCIe, SATA and peripheral connectors to components as needed. Ensure the PSU is secured to the case, that airflow is not obstructed around the 120 mm fan, and that AC mains voltage matches the specified 115–240 V range before powering on.

Recommendations

For stable operation, pair the C750 with single mid-range GPUs (around RTX 3060–3070 class) or systems whose total component draw does not exceed the 750 W rating. Allow adequate case ventilation, perform periodic dust cleaning of the fan, and verify connector seating during installation to maintain efficiency and longevity.
