Review

The Corsair RM750 750 Watt Modular White power supply is a noteworthy entry in Corsair's RM series, promising reliable power delivery along with advanced features like 80 PLUS Gold efficiency and a fully modular design. Its strategic combination of components and design choices aim to balance performance with silent operation, providing PC enthusiasts a compelling choice for high-performance builds.

Performance and Efficiency

The Corsair RM750 offers a remarkable 80 PLUS Gold certification, which translates to an efficiency range of 88-91%. This efficiency is reflected even under light loads, thanks to a newer resonant controller on the primary side that allows for higher burst-mode efficiency Tom's Hardware. Additionally, the inclusion of Modern Standby mode provides quick wake times, an innovation tailored to modern Windows OS environments Tom's Hardware.

Build Quality and Design

As expected from a Corsair product, the RM750 boasts robust build quality. While it utilizes Chinese Elite caps, a choice often viewed as a trade-off against Japanese caps, the conducted product engineering compensates with strong soldering and a stable performance profile Tom's Hardware. Moreover, the use of a 140mm Hong Hua rifle-bearing fan ensures an efficient cooling solution, though some might prefer the NR135L fan found in the RM750x variant for even quieter operation.

Silence and Thermal Management

A defining feature of the Corsair RM750 is its low-noise operation. The semi-passive mode keeps the fan off until medium loads, contributing to a noise level classified under LAMBDA-A standards, which averages 20-25 dB(A)Tom's Hardware. This design allows quiet operations, suitable for builds in noise-sensitive environments without the need for manual override.

Compatibility and Modular Design

The fully modular design provides the flexibility any advanced PC builder desires. Cable management is simplified, optimizing airflow and aesthetic tidiness in the build. The RM750 also includes two EPS and six PCIe connectors, making it suitable for most single or dual GPU configurations, and more than ample for a 750W rated supply Tom's Hardware.

Protection and Reliability

Offering comprehensive protection mechanisms, the Corsair RM750 includes over-voltage, under-voltage, over-power, and short-circuit protections, among others. These make it a reliable choice for safeguarding components against power anomalies. A 10-year warranty further underscores Corsair's confidence in the RM750's long-term reliability Tom's Hardware.

Final Verdict

The Corsair RM750 750 Watt Modular White emerges as a strong contender in the power supply market, particularly for those who value efficiency, silent operation, and modular flexibility. While there are minor critiques regarding capacitor choice and fan selection, these do not detract from its overall appeal for high-end systems requiring assured power delivery and functional versatility.
