Power Supply Unit Corsair RM750x SHIFT 750 W

The Corsair RM750x SHIFT 750 W is a fully modular power supply unit designed for desktop PCs and servers that require reliable, efficient power delivery. It provides 750 watts of continuous output through a 24-pin ATX motherboard connector and supports AC input from 100 to 240 V at 47–63 Hz. The PSU is 80 PLUS Gold certified and incorporates a 140 mm fluid dynamic bearing fan with Zero RPM mode for quiet operation under light loads. The unit includes a 61 cm motherboard power cable and multiple SATA power cable lengths (455, 570, 685, 800 mm), and comes in a black finish with a compact form factor compatible with ATX-standard cases that allow side access to the modular panel.

Advantages

The RM750x SHIFT combines ATX 3.0 certification and an 80 PLUS Gold efficiency rating to deliver stable power with up to approximately 90% efficiency under typical load conditions. Its patent-pending side-mounted modular connections simplify cable installation and management by providing easy access to connectors. Fully modular CORSAIR Type 5 micro-fit cables reduce clutter and improve airflow inside the case. The included PCIe 5.0 12VHPWR GPU cable supports modern high-power graphics cards. Industrial-grade 105°C-rated Japanese capacitors contribute to long-term reliability and thermal stability.

How to use

Install the RM750x SHIFT into a PC case that supports ATX-format PSUs and provides side access to the modular connection panel. Secure the PSU to the case using the standard mounting points, then route only the required fully modular cables to the motherboard, GPU, storage devices and peripherals. Connect the 24-pin ATX cable to the motherboard and use the included PCIe 5.0 12VHPWR cable for compatible graphics cards. Ensure AC mains input is within the specified 100–240 V range before powering on. Follow standard ESD precautions and verify all connections are fully seated before starting the system.

Recommendations

For optimal airflow and cable management, use only the supplied CORSAIR Type 5 micro-fit cables and position the PSU so the side modular panel remains accessible. Monitor operating temperatures under sustained heavy loads, and ensure the case provides adequate ventilation. When installing high-power GPUs, confirm the GPU cable connection type and power requirements match the included PCIe 5.0 12VHPWR cable.
