CORSAIR RM850e vs Cooler Master MWE 750 Gold V2 Fully Modular PSU

Price Comparison

The CORSAIR RM850e is significantly more affordable than the Cooler Master MWE 750 Gold V2, priced at £85.99 compared to £141.41. This £55.42 difference makes the RM850e a more budget-friendly option, particularly for users seeking a reliable power supply without breaking the bank. While it’s essential to evaluate performance and features alongside cost, the RM850e clearly stands out for those on a tighter budget. This price point may appeal to gamers and builders who wish to allocate more funds to other components within their systems.

Efficiency and Performance

When it comes to efficiency, the Cooler Master MWE 750 Gold V2 takes the lead with an 80 PLUS Gold certification, boasting a 90% efficiency under typical loading conditions. This high efficiency not only translates to potential savings on utility costs but also improves overall system performance by minimising heat generation. The CORSAIR RM850e, while not as explicitly rated for efficiency, is Intel ATX 3.1 certified, ensuring it can handle the demands of modern graphics cards and power-hungry components. However, if energy efficiency is a primary concern, the Cooler Master model is a better choice.

Modular Design

Both power supplies offer fully modular designs, allowing users to connect only the cables necessary for their builds. The CORSAIR RM850e's fully modular cabling aims to enhance reliability and efficiency while reducing unnecessary clutter inside the case. In contrast, the Cooler Master MWE 750 Gold V2 features flat black cabling, which not only promotes sophisticated aesthetics but also improves internal ventilation by eliminating excess cables that can restrict airflow. This focus on aesthetics and airflow management may appeal to those prioritising both functionality and style in their builds.

Cooling Solutions

The cooling solutions differ between the two models. The CORSAIR RM850e utilises a 120mm rifle-bearing fan designed to maintain low noise levels even under full load, which is an attractive feature for gamers or users who prefer quieter systems. The Cooler Master MWE 750 Gold V2 employs a responsive hydro-dynamic bearing (HDB) fan that adjusts its speed based on temperature, effectively reducing noise during low-demand periods. While both fans are designed to mitigate noise, the MWE 750 Gold V2's temperature-responsive feature may offer a more dynamic and adaptable cooling solution.

Temperature Tolerance

The Cooler Master MWE 750 Gold V2 is rated for a higher temperature threshold of 50°C, compared to the standard operational temperatures of many competitors. This increased tolerance makes it a suitable choice for users who engage in overclocking or intensive tasks like real-time 3D rendering. In contrast, the temperature tolerance for the CORSAIR RM850e isn’t specified, but it does feature 105°C-rated capacitors to ensure reliable power delivery. For those pushing their systems to the limit, the MWE 750 Gold V2’s higher tolerance may provide peace of mind.

Connector Versatility

In terms of connector versatility, the Cooler Master MWE 750 Gold V2 includes a broad array of connectors, such as 2 EPS connectors for universal motherboard compatibility, making it a flexible choice for various system builds. With a total of 12 SATA connectors and numerous PCIe connectors, it caters well to high-performance setups. The CORSAIR RM850e also offers a reliable range of connections but does not specify the total number of connectors available. For users with extensive setups requiring multiple connections, the Cooler Master model provides an edge in terms of versatility.

Brand Reputation and Support

Both Corsair and Cooler Master are well-regarded brands in the power supply market. Corsair is known for its high-quality components and robust customer support, which adds a layer of trust for consumers. Similarly, Cooler Master has built a solid reputation over the years, particularly in the gaming and performance spaces. When selecting between the two, brand loyalty and past experiences with customer service may influence a buyer's decision, but both brands uphold a reputation for reliability and performance.

Which should you buy?

Choosing between the CORSAIR RM850e and the Cooler Master MWE 750 Gold V2 ultimately depends on your specific needs and budget. The RM850e is an excellent choice for those seeking an affordable, reliable power supply without the need for top-tier efficiency or extensive connector options. On the other hand, if you prioritise efficiency, aesthetics, and higher temperature tolerance, the Cooler Master MWE 750 Gold V2 justifies its higher price with its superior features. For budget-conscious users, the CORSAIR RM850e presents a compelling option, while the Cooler Master model suits those who are willing to invest more for enhanced performance and flexibility.
