Corsair RMx SHIFT Series 750W 80+ Gold Fully Modular Power Supply


CORSAIR RMx SHIFT Series fully modular power supplies boast a revolutionary side cable interface to keep all your connections within quick reach, for exceptionally convenient 80 PLUS Gold efficient power. With fully modular micro-fit connections and ATX 3.0 compliance, RMx SHIFT makes clean PC builds and upgrades even easier. RMx SHIFT PSUs use Japanese 105°C-rated electrolytic capacitors, for long life and reliability backed by a ten-year warranty. A 140mm fluid dynamic bearing fan utilizes a specially calculated fan curve for high performance and reliability with low noise, while Zero RPM mode support ensures virtually silent operation at low and medium loads. For quiet, efficient, and accessible power, put an RMx SHIFT Series PSU on your side.


An innovative side PSU panel with modular connectors allows you to comfortably plug connections into the side face of the PSU, making it easier to access and manage than ever before.


Fully modular, CORSAIR Type 5 Gen 1 micro-fit PSU cables, so you only connect the cables your system needs while taking up less space.


The ATX 3.0 standard demands a high level of power efficiency and reliability. Whilst many of CORSAIRS PSUs meet these requirements RMx Shift series PSUs are formally certified for ATX 3.0 compliance. PCIe 5.0 12VHPWR GPU cables are included for use with modern graphics cards such as the NVIDIA GeForce RTX 40 Series.


A low-friction, fluid dynamic bearing 140mm fan with Zero RPM mode support ensures your PSU runs cool while staying virtually silent when not under high load.


Steady power output at up to 90% efficiency, and Cybenetics-certified for lower power consumption, less noise, and cooler temperatures.


Built with 100% Industrial-grade, 105°C-rated Japanese electrolytic capacitors for unwavering power and reliability.


The PSU and cables will fit in any PC case that supports ATX PSU format and is at least 210mm (8.3") wide. The PSU must also be accessible from the side when mounted in the case.
