MSI MAG A750GL PCIE5 Power Supply Unit vs CORSAIR RM850e

Price Comparison

When comparing the prices of the MSI MAG A750GL and the CORSAIR RM850e, the MSI unit is the more budget-friendly option at £74.99, while the Corsair unit costs £85.99. This means that the MSI offering is £11 cheaper, making it an attractive choice for those looking to save on their power supply purchase. The price difference may be significant for budget-conscious consumers, especially when building a high-performance system where multiple components can quickly add up.

Efficiency Ratings

The MSI MAG A750GL boasts an 80 PLUS Gold certification, indicating it operates at up to 90% efficiency under typical loads. This is particularly beneficial for users with high-power components, as it helps reduce energy consumption and heat generation. In contrast, the CORSAIR RM850e is Intel ATX 3.1 certified, which supports the latest PCIe 5.1 platforms and can withstand 2x transient power excursions. While both units are designed for efficiency, the MSI has a clear edge in the efficiency rating, making it a better choice for energy-conscious consumers.

Modular Design

Both power supplies feature a fully modular design, allowing users to connect only the cables they need for their system build. The MSI MAG A750GL includes flat black cables and a cable bag, which helps reduce clutter and improve airflow in the chassis. The CORSAIR RM850e also promotes efficient cable management with its fully modular cabling. While both designs facilitate a clean build, the MSI's additional emphasis on airflow may provide a slight advantage in maintaining optimal system temperatures.

Cooling Solutions

Cooling is a critical aspect of any power supply, and both units utilise efficient fan designs to ensure reliable operation. The MSI MAG A750GL features a 120mm fluid dynamic bearing fan that provides effective cooling performance, while the CORSAIR RM850e is equipped with a 120mm rifle bearing fan designed to keep noise levels low, even under full load. Both cooling solutions are robust, but the MSI's fluid dynamic bearing design may offer enhanced longevity and performance due to its superior heat dissipation capabilities.

Compatibility Features

The MSI MAG A750GL is designed to support PCIe 5.0 GPUs, featuring a native 16-pin (12V2x6) PCIe connector that can deliver up to 450W of power. This makes it well-suited for high-end gaming setups and demanding hardware configurations. On the other hand, the CORSAIR RM850e's compliance with the Intel ATX 3.1 standard ensures compatibility with the latest technology, including PCIe 5.1 platforms. While both power supplies support modern GPUs, the MSI's higher power output may be more beneficial for users with power-hungry components.

Build Quality and Durability

In terms of build quality, the MSI MAG A750GL is designed with a full-bridge LLC topology and includes several protective features such as Over Current Protection (OCP) and Over Voltage Protection (OVP). It also comes with a 7-year limited warranty, indicating a commitment to durability and reliability. The CORSAIR RM850e utilises 105°C-rated capacitors to deliver steady and reliable power, ensuring dependable performance over time. Both units are built with longevity in mind, but the extended warranty on the MSI may provide additional peace of mind for consumers.

User Experience and Noise Levels

User experience can greatly influence the overall satisfaction with a power supply, and both the MSI MAG A750GL and the CORSAIR RM850e strive to provide a quiet operation. The MSI’s 120mm fan is designed to offer reliable cooling without excessive noise, while the CORSAIR unit features a specially calculated fan curve that minimises noise even at full load. While both power supplies aim to maintain a silent operation, users may find the Corsair's focus on low-noise performance particularly appealing in quieter environments.

Which should you buy?

Ultimately, the decision between the MSI MAG A750GL and the CORSAIR RM850e hinges on specific user needs and preferences. The MSI MAG A750GL stands out with its 80 PLUS Gold certification, lower price of £74.99, and robust support for PCIe 5.0 GPUs, making it an excellent choice for those prioritising efficiency and cost-effectiveness. Conversely, the CORSAIR RM850e offers modern certifications and a focus on low-noise operations at £85.99, appealing to users who seek cutting-edge compatibility and quieter performance. Your choice should reflect whether you value efficiency and price or advanced compatibility and silent operation more.
