Corsair RM750e ATX 3.1 Gold Fully Modular White SMPS

The Corsair RMe Series RM750e is a 750-watt fully modular ATX power supply finished in white, designed for enthusiast PC builds that demand clean power delivery, quiet operation, and forward-looking connector support. It carries Intel ATX 3.1 certification and PCIe 5.1 compliance, meaning it meets the latest platform standards out of the box and is ready for current and upcoming high-performance graphics cards. At the heart of the RM750e's power design is a resonant LLC topology paired with DC-DC conversion, a combination known for stable voltage regulation and low ripple across the 12V, 5V, and 3.3V rails. All capacitors are rated to 105°C industrial grade, contributing to the unit's stated 100,000-hour MTBF figure and supporting long-term reliability in demanding environments. The RM750e ships with a native 600W-capable 12V-2x6 GPU power cable — the connector introduced with PCIe 5.1 — alongside three 6+2-pin PCIe connectors, two EPS connectors, six SATA connectors, and two PATA connectors, providing broad compatibility for multi-drive and high-end CPU configurations. All cables are Type 4 ultra-flexible embossed cables with low-profile combs, making routing in compact cases noticeably easier. Efficiency is Cybenetics Gold certified, delivering up to 89% overall efficiency with a Cybenetics Noise rating of A, reflecting genuinely quiet electrical operation. The 120mm rifle-bearing fan employs a purpose-tuned fan curve and Zero RPM mode at low and moderate loads, so the unit runs silently during everyday desktop and light gaming use. The compact 140 mm casing (dimensions: 140 × 150 × 86 mm) fits comfortably in modern mid-tower and compact ATX cases with room to spare for cable management. Modern Standby support enables near-instant wake- sleep response, a feature increasingly relevant for Windows 11 platforms. The dual-colour 12V-2x6 connector provides a visual confirmation of a secure GPU connection, reducing the risk of loose seating.
