This article covers Corsair RM750e Fully Modular Low-Noise ATX Power Supply.

Overview

The Corsair RM750e is a fully modular ATX power supply unit rated at 750W with 80PLUS Gold certification. Part of Corsair's RMe series, it targets the mid-range market segment, balancing quiet operation, high efficiency, and reliable components. Industrial-grade 105°C-rated capacitors ensure long-term stability under load. This PSU features dual 8-pin EPS12V connectors and multiple PCIe 8-pin connectors, making it suitable for mid-to-high-end gaming PCs and creator workstations equipped with modern multi-core CPUs and graphics cards. Modern Standby support enables fast wake-from-sleep and low standby power consumption. With a compact 140mm chassis length, the RM750e fits easily into most mid-tower and full-tower cases. The fully modular cable design lets you connect only the cables you need, simplifying cable management and improving airflow inside the case.

Compatibility Guide

Form Factor: Standard ATX (PS/2) – compatible with the vast majority of mid-tower and full-tower PC cases. CPU Power: Dual 8-pin EPS12V connectors support Intel LGA1700/1200/115x and AMD AM5/AM4 motherboards requiring one or two 8-pin (or 4+4-pin) CPU power connections. GPU Power: Multiple PCIe 8-pin connectors provide sufficient power for mid-range to upper-mid-range graphics cards such as the GeForce RTX 4070 or Radeon RX 7800 XT. Storage & Peripherals: Standard SATA and peripheral connectors are included for SSDs, HDDs, and fan hubs. * Note: The RM750e does not include a native 12VHPWR (12V-2x6) connector. For GeForce RTX 40-series and later GPUs that use this connector, you will need to use the included 8-pin to 12VHPWR adapter cable.

Product Info

Released in late 2022, the Corsair RM750e is a mid-range PSU offering 80PLUS Gold efficiency and full modularity at an accessible price point (typically around $100–$130 USD). It carries a 7-year manufacturer warranty, providing peace of mind for long-term use. The unit delivers a single +12V rail rated at 62.5A (750W). A 135mm low-noise fan supports a zero-RPM mode, keeping the fan completely off under light loads for silent operation. Japanese 105°C-rated capacitors are used throughout for enhanced reliability and longevity.

Best Use Cases

Mid-Range Gaming PC Builders: Ideal for systems pairing a Core i5/Ryzen 5 CPU with a GeForce RTX 4060 Ti or Radeon RX 7700 XT GPU. The 750W capacity provides ample headroom for stable operation under gaming loads. Noise-Conscious Users: The zero-RPM fan mode ensures silent operation during everyday tasks like web browsing, office work, or video playback. The 135mm fan itself is also tuned for low noise. First-Time Modular PSU Users: The fully modular design simplifies cable routing, making it an excellent choice for beginners who want a clean-looking build without the clutter of unused cables.

Things to Consider

No Native 12VHPWR Connector: If you plan to use a high-end GeForce RTX 40-series or future GPU that requires a 12VHPWR connector, you will need to rely on the included adapter cable. This adds a potential point of cable management complexity. 750W Capacity Ceiling: For builds pairing a flagship CPU (Core i9 / Ryzen 9) with a top-tier GPU (RTX 4080 SUPER or higher) under sustained full load, 750W may be insufficient. Consider an 850W or higher unit for such configurations. Competition: In the same price and efficiency bracket, alternatives like the Seasonic Focus GX-750 and be quiet! Straight Power 11 750W offer similar specs. The RM750e stands out with its compact 140mm length and 7-year warranty, but fan noise profile and personal brand preference may sway the decision.
