Overview:

CORSAIR RMx SHIFT Series fully modular power supplies boast a revolutionary patent-pending side cable interface to keep all your connections within easy reach, for exceptionally convenient 80 PLUS Gold efficient power.

Features:

SIDE MOUNTED CONNECTIONS
An innovative patent-pending side PSU panel with modular connections lets you comfortably plug cables into the side face of the PSU, making it easier to connect and manage your cables than ever before.

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

CORSAIR TYPE 5 MICRO-FIT CONNECTORS
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.

140mm FAN WITH ZERO RPM MODE SUPPORT
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.

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

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

CASE COMPATIBILITY
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.
