Corsair RM750e ATX 3.1 Gold Fully Modular SMPS

The Corsair RM750e is a 750-watt fully modular ATX power supply from the RMe Series, designed for builders who demand reliable, efficient, and quiet power delivery in a compact chassis. Certified to the Intel ATX 3.1 standard and compliant with PCIe 5.1, it ships with a native 12V-2×6 GPU power cable rated for up to 600 W continuous output, making it compatible with modern and next-generation graphics cards without requiring an adapter. Efficiency is rated at Cybenetics Gold, meaning the unit achieves up to 90% efficiency under typical operating loads, which translates to lower power consumption, reduced heat output, and quieter operation compared to lower-rated units. Cooling is handled by a 120mm rifle-bearing fan paired with a purpose-tuned fan curve; a Zero RPM mode keeps the fan completely stopped at low and medium loads, and only spins up when thermals demand it. The fully modular cabling system lets you connect only the cables your build requires, cutting down on clutter and improving airflow inside the case. Cables use a Type 4 ultra-flexible embossed design with low-profile combs for easier routing. The compact 140mm chassis length fits comfortably in the majority of mid-tower and full-tower ATX cases on the market today. Internally, the RM750e is built around a resonant LLC topology with DC-DC conversion stages, supported by 105 °C-rated industrial-grade capacitors for long-term reliability. Modern Standby support ensures rapid wake- sleep response and improved low-load efficiency for always-on desktop workloads.
