CORSAIR SF850 vs Cooler Master MWE 750 Gold V2 Fully Modular PSU

Overview of the Power Supplies

In the world of power supplies, the CORSAIR SF850 and Cooler Master MWE 750 Gold V2 stand out for their performance and efficiency. The SF850 is priced at £149.99, while the MWE 750 Gold V2 is slightly cheaper at £141.41. Both power supplies are fully modular, but they cater to different needs in terms of power output and efficiency ratings.

The CORSAIR SF850 features an impressive 80 PLUS Platinum rating, ensuring high efficiency and lower energy consumption. In contrast, the Cooler Master MWE 750 Gold V2, with its 80 PLUS Gold rating, delivers 90% efficiency under typical loading, making it a solid choice for gaming systems. These distinctions make each power supply suitable for different user preferences and system requirements.

Efficiency Ratings

The efficiency rating of a power supply is crucial for energy conservation and performance. The CORSAIR SF850 boasts an 80 PLUS Platinum certification, indicating it exceeds 90% efficiency at typical loads. This means it converts more electricity into usable power while minimising waste heat, which is essential for high-performance systems.

On the other hand, the Cooler Master MWE 750 Gold V2 has an 80 PLUS Gold rating, achieving 90% efficiency under typical loading conditions. While this is slightly lower than the SF850, it remains an excellent choice for users seeking to save on utility costs and reduce heat generation. Both power supplies excel in efficiency, but the CORSAIR SF850 takes the lead with its superior Platinum rating.

Power Output

When it comes to power output, the CORSAIR SF850 provides a robust 850 watts, making it ideal for power-hungry components and systems with high energy demands. This extra headroom is particularly beneficial for users with top-tier graphics cards or those who plan to overclock their CPUs.

Conversely, the Cooler Master MWE 750 Gold V2 offers 750 watts, which is suitable for most gaming setups and mid-range systems. While it may fall short of the SF850 in raw power, it still meets the needs of gamers and casual users alike. The difference in wattage may influence your choice depending on the specific requirements of your build.

Build Quality and Components

Build quality is a significant factor in the longevity and reliability of a power supply. The CORSAIR SF850 is equipped with 105°C rated Japanese capacitors, which enhance its reliability and performance under load. This choice of high-quality components contributes to the unit's overall durability and efficiency.

In comparison, the Cooler Master MWE 750 Gold V2 features a higher temperature threshold of 50°C, up from the original model's 45°C. This improvement allows it to handle more demanding tasks, such as overclocking or real-time rendering, without compromising performance. Both power supplies are constructed with quality in mind, but the SF850 may provide a slight edge in component resilience.

Cooling Solutions

Effective cooling is vital for maintaining optimal performance and prolonging the lifespan of power supplies. The CORSAIR SF850 utilises a 92mm PWM cooling fan designed for low-noise operation, which is essential for users who value a quiet computing experience. This fan helps maintain a cool environment within compact cases, ensuring stable performance even under heavy loads.

The Cooler Master MWE 750 Gold V2, on the other hand, employs a 120mm hydro-dynamic bearing (HDB) fan with temperature-responsive speed control. This feature not only enhances cooling efficiency but also reduces noise during low-demand periods. While both cooling solutions are effective, the larger fan in the MWE 750 Gold V2 may provide slightly better airflow and cooling performance.

Cable Management

Cable management can drastically affect the aesthetics and airflow within a PC case. The CORSAIR SF850 features fully modular, Type-5 Micro-Fit PSU connectors, allowing for flexible cabling options. This design is particularly advantageous for small-form-factor builds, as it minimises clutter and optimises space.

Similarly, the Cooler Master MWE 750 Gold V2 also offers fully modular flat black cabling. This allows for sophisticated case build aesthetics while improving internal ventilation by reducing unnecessary cables that can obstruct airflow. Both power supplies excel in cable management, but the unique connector design of the SF850 may offer additional flexibility in tight spaces.

Compatibility and Connectors

Compatibility with various components is essential when selecting a power supply. The CORSAIR SF850 is ATX 3.1 compliant and PCIe 5.1 ready, making it a future-proof choice for users looking to upgrade their systems. This compliance ensures it can handle the latest hardware advancements without issue.

The Cooler Master MWE 750 Gold V2 includes two EPS connectors for universal motherboard compatibility, along with a comprehensive array of connectors, including ATX 24 Pin, EPS 4+4 Pin, and multiple PCI-e connectors. While both power supplies offer extensive compatibility, the SF850's adherence to the latest standards may make it more appealing for users seeking cutting-edge performance.

Which should you buy?

Choosing between the CORSAIR SF850 and the Cooler Master MWE 750 Gold V2 ultimately depends on your needs and preferences. If you require higher power output and superior efficiency, the SF850, priced at £149.99, is an excellent investment, especially for high-performance builds. However, if you're looking for a reliable power supply at a slightly lower price of £141.41, the MWE 750 Gold V2 offers commendable features and performance suitable for most gaming systems. Both power supplies are well-regarded, making either a solid choice for your setup.
