CORSAIR RM850x Fully Modular Low-Noise ATX Power vs MSI MAG A750GLS PCIE5, Fully Modular Compact

Overview of the Power Supplies

The CORSAIR RM850x and the MSI MAG A750GLS are two highly regarded power supplies, both equipped with modern features for optimal performance. While the CORSAIR RM850x is priced at $161.93, the MSI MAG A750GLS offers a more budget-friendly option at $89.99, making it about 44% cheaper. Both units are fully modular, enabling users to connect only the cables they need, thus enhancing cable management and airflow within the PC case.

Efficiency Ratings

Efficiency is a critical factor when selecting a power supply. The CORSAIR RM850x holds a Cybenetics Gold certification, boasting up to 91% efficiency, which translates to lower power consumption and reduced heat generation. In comparison, the MSI MAG A750GLS is also 80 PLUS Gold certified, with an efficiency rating of up to 90%. While both power supplies offer excellent efficiency, the CORSAIR RM850x edges out slightly in terms of energy savings, making it a compelling choice for eco-conscious users.

Compatibility with Modern Standards

When it comes to compatibility with the latest hardware, both power supplies are compliant with ATX 3.1 standards and support PCIe 5.1, making them suitable for the newest generation of graphics cards. The CORSAIR RM850x features a native 12V-2x6 connector, ensuring a direct connection to the latest GPUs without the need for adapters. The MSI MAG A750GLS also includes native 12V-2x6 connectors, capable of delivering up to 600W to support demanding PCIe 5.1 graphics cards. This ensures that both units are well-equipped for high-performance builds.

Noise Levels

Noise output is another essential consideration for many gamers and PC builders. The CORSAIR RM850x is designed for low noise operation, with a 140mm Fluid Dynamic Bearing (FDB) fan that ensures quiet cooling. The MSI MAG A750GLS, on the other hand, features a slightly smaller 135mm FDB fan, which also operates quietly. Both power supplies maintain low noise levels, making them suitable for builds where silence is a priority. However, the CORSAIR model may offer a slight edge with its larger fan, potentially leading to quieter operation under load.

Build Quality and Design

In terms of build quality, both power supplies are constructed to high standards. The CORSAIR RM850x utilizes 100% Japanese 105°C-rated electrolytic capacitors, which enhance its electrical performance and longevity. The MSI MAG A750GLS features a robust design with an LLC half-bridge and DC-to-DC converter, providing reliable output under various conditions. Both units promise durability and reliability, but the emphasis on premium components in the CORSAIR RM850x may appeal more to enthusiasts looking for top-tier performance.

Warranty and Support

Warranty length is an important factor when investing in a power supply. The CORSAIR RM850x is backed by a ten-year warranty, which provides peace of mind regarding its longevity and reliability. Similarly, the MSI MAG A750GLS also offers a ten-year warranty, ensuring that users have long-term support for their investment. This parity in warranty length means that both products are equally appealing in terms of manufacturer support, giving buyers confidence in their purchase.

User Experience and Installation

The user experience during installation can greatly impact overall satisfaction. The CORSAIR RM850x features ultra-flexible embossed cables, making it easier to manage and connect the necessary cables without hassle. The MSI MAG A750GLS also boasts embossed jacket cables, ensuring a tidy setup. Both power supplies are designed to simplify the installation process, though the added flexibility of the CORSAIR cables may offer a slightly smoother experience for complex builds.

Which should you buy?

Ultimately, the choice between the CORSAIR RM850x and the MSI MAG A750GLS depends on your specific needs and budget. The CORSAIR RM850x is a premium option with higher efficiency, superior build quality, and a slight edge in noise levels, making it ideal for high-end builds and users who prioritize performance. Conversely, the MSI MAG A750GLS provides similar features at a significantly lower price of $89.99, making it an attractive option for budget-conscious buyers who still want reliable performance. If budget is not a constraint and you prefer the best efficiency and quality, the CORSAIR RM850x is the way to go. However, if you seek value without sacrificing essential features, the MSI MAG A750GLS is a commendable choice.
