CORSAIR RM750e vs Cooler Master MWE 750 Gold V2 Fully Modular PSU

Overview of Power Supply Units

When it comes to power supplies, the choice between the CORSAIR RM750e and the Cooler Master MWE 750 Gold V2 is crucial for building a reliable and efficient PC. The CORSAIR RM750e is priced at £81.99, while the Cooler Master MWE 750 Gold V2 sits significantly higher at £141.41. Both units are fully modular, offering flexibility in cable management, but they cater to slightly different needs and preferences.

Efficiency and Performance

The CORSAIR RM750e boasts compliance with the Intel ATX 3.1 standard and is designed to support PCIe 5.1 platforms, ensuring it can handle significant power demands. In contrast, the Cooler Master MWE 750 Gold V2 is certified with an 80 PLUS Gold rating, achieving up to 90% efficiency under typical loading conditions. This higher efficiency can lead to savings on electricity costs, particularly important for users running high-performance systems.

Noise Levels

When it comes to noise, the CORSAIR RM750e features a 120mm rifle bearing fan that is engineered to maintain low noise levels, even under full load. This design philosophy is particularly beneficial for users who value a quiet operating environment. On the other hand, the Cooler Master MWE 750 Gold V2 also employs a 120mm hydro-dynamic bearing fan, which uses temperature-responsive fan-speed control to minimise noise during periods of low demand. While both units prioritise quiet operation, the specifics of their fan technologies may appeal differently to users depending on their noise tolerance.

Build Quality and Components

The CORSAIR RM750e is equipped with 105°C-rated capacitors, which contribute to its reliability and performance over time. This feature is particularly advantageous for users seeking a long-lasting power supply. In comparison, the Cooler Master MWE 750 Gold V2 is built with a higher temperature resilience of 50°C, up from the original model's 45°C. This enhancement makes it a strong contender for overclocking and high-performance tasks, providing peace of mind for users pushing their systems to the limit.

Cable Management

Both power supplies offer fully modular designs, but they approach cable management differently. The CORSAIR RM750e's fully modular cabling allows users to connect only the necessary cables for their build, keeping the interior tidy and improving airflow. The Cooler Master MWE 750 Gold V2 also features fully modular flat black cabling, which not only enhances aesthetics but also aids in internal ventilation by reducing clutter. This design is particularly appealing for users who prioritise a clean and well-organised case.

Compatibility and Connectors

Compatibility is essential when selecting a power supply, and both units cater to a wide range of setups. The CORSAIR RM750e supports modern components thanks to its Intel ATX 3.1 certification. Meanwhile, the Cooler Master MWE 750 Gold V2 includes two EPS connectors, ensuring universal motherboard compatibility, along with a broad variety of connectors such as ATX 24 Pin, SATA, and PCI-e. This extensive connector array makes the Cooler Master MWE 750 Gold V2 suitable for diverse builds, including those with multiple GPUs.

Thermal Performance

Thermal performance is another critical aspect to consider. The CORSAIR RM750e's design prioritises quiet operation and efficient cooling, with its fan curve carefully calculated to reduce noise even under load. Conversely, the Cooler Master MWE 750 Gold V2’s higher temperature threshold of 50°C allows it to maintain performance in more demanding scenarios, such as gaming or intensive rendering tasks, without overheating. This difference can be crucial for users who frequently engage in high-stress computing activities.

Which should you buy?

Choosing between the CORSAIR RM750e and the Cooler Master MWE 750 Gold V2 ultimately depends on your specific needs and budget. The CORSAIR RM750e offers exceptional value at £81.99, with reliable performance and quiet operation, making it ideal for standard gaming or office setups. However, for those willing to invest more at £141.41, the Cooler Master MWE 750 Gold V2 delivers superior efficiency, extensive compatibility, and enhanced thermal performance, making it a better fit for high-demand applications. If you prioritise energy efficiency and are building a high-performance system, the Cooler Master unit may justify its higher price. Conversely, if you need a solid and quieter option for a more modest build, the CORSAIR RM750e is a strong contender.
