MSI MAG A750GL PCIE5 Power Supply Unit vs CORSAIR RM750e

Overview of the MSI MAG A750GL and CORSAIR RM750e

The MSI MAG A750GL is priced at £74.99, while the CORSAIR RM750e costs £81.99. Both power supplies are designed to meet the demands of modern computing but differ in features and efficiency ratings.

The MSI MAG A750GL is an 80 PLUS Gold certified power supply, ensuring high energy efficiency, making it suitable for high-performance builds, particularly those featuring powerful GPUs and CPUs. In contrast, the CORSAIR RM750e is Intel ATX 3.1 certified, which means it also supports the latest hardware standards and offers reliable performance under load.

Power Efficiency

The MSI MAG A750GL boasts an 80 PLUS Gold certification, meaning it operates at up to 90% efficiency, significantly reducing energy consumption and heat production. This efficiency rating is particularly beneficial for users with high-end components, as it helps maintain stable power delivery while keeping electricity costs lower.

On the other hand, the CORSAIR RM750e does not specify an efficiency rating equivalent to that of the MSI but is compliant with the ATX 3.1 standard. The RM750e is designed to handle transient power excursions effectively, although it does not highlight a specific efficiency percentage like the MSI. For users prioritising energy efficiency, the MSI MAG A750GL takes the lead.

Build Quality and Design

The MSI MAG A750GL features a compact design with a length of just 140mm, which allows for better airflow and cable management within the PC case. It includes a 120mm fluid dynamic bearing fan that provides reliable cooling performance, ensuring the unit operates efficiently even under load.

Conversely, the CORSAIR RM750e is equipped with a 120mm rifle bearing fan designed to keep noise levels down, even when the PSU is operating at full capacity. Its fully modular design allows users to connect only the cables they need, reducing clutter and improving airflow. Both units exhibit robust build quality, but the MSI's compact size may be more advantageous for tighter builds.

Modularity and Connectivity

The MSI MAG A750GL is a fully modular power supply, which simplifies the installation process and allows users to manage cables more effectively. It includes a native 16-pin PCIe connector that can deliver up to 450W of power to PCIe 5.0 GPUs, accommodating even the most demanding graphics cards.

The CORSAIR RM750e also features a fully modular design, allowing for flexible cable management. It is compatible with PCIe 5.1 and can handle 2x transient power excursions, which is particularly beneficial for high-performance GPUs. While both power supplies excel in modularity, the MSI has the edge in the power it can deliver to GPUs.

Noise Levels

The MSI MAG A750GL utilises a fluid dynamic bearing fan, which is known for its quiet operation and longevity. This design helps ensure that the power supply remains relatively silent even during peak performance.

In comparison, the CORSAIR RM750e is designed with a specially calculated fan curve that aims to minimise noise levels, ensuring that it operates quietly, even under full load. While both power supplies focus on reducing noise, the MSI's fan design may provide a quieter experience overall, particularly in quieter environments.

Warranty and Reliability

MSI offers a generous 7-year limited warranty with the MAG A750GL, underscoring its commitment to reliability and customer satisfaction. This warranty period reflects the manufacturer's confidence in the product's durability and performance.

The CORSAIR RM750e does not specify a warranty period in the provided data. However, Corsair is known for producing reliable components, and their products typically come with competitive warranties. The extended warranty from MSI may offer additional peace of mind for users concerned about long-term reliability.

Compatibility with Modern Hardware

The MSI MAG A750GL is designed to support the latest high-demand hardware, including PCIe 5.0 GPUs. Its ability to handle transient power excursions makes it suitable for high-performance gaming and content creation rigs that require substantial power delivery.

The CORSAIR RM750e is compliant with the ATX 3.1 standard and supports PCIe 5.1, which means it is also well-equipped to handle the latest GPUs and high-performance components. Both power supplies are future-proofed to some extent, but the specific compatibility with different PCIe standards may influence user choice based on their current or planned hardware.

Which should you buy?

Choosing between the MSI MAG A750GL and the CORSAIR RM750e ultimately depends on your specific needs and preferences. The MSI MAG A750GL provides excellent energy efficiency with its 80 PLUS Gold certification, a compact design, and a long warranty period, making it a strong contender for users focused on efficiency and reliability. Priced at £74.99, it offers solid value for high-performance builds.

On the other hand, the CORSAIR RM750e, at £81.99, is also a robust choice with its compliance with the latest ATX standard, a quiet operation, and fully modular design. It is ideal for those who prioritise modern features and low noise levels.

In conclusion, for gamers and power users looking for high efficiency and value, the MSI MAG A750GL is the better choice. However, if you prefer the latest standards and quieter operation for a slightly higher price, the CORSAIR RM750e is well worth considering.
