CORSAIR CX550 80 Plus Bronze Non Modular Low-Noise ATX vs MSI MAG A750GLS PCIE5, Fully Modular Compact

Price Comparison

The CORSAIR CX550 is priced at $65.99, making it about 17% cheaper than the MSI MAG A750GLS, which retails for $89.99. This significant price difference can be a decisive factor for budget-conscious gamers or PC builders. While both power supplies offer reliable performance, the cost-effectiveness of the CORSAIR model may appeal more to those who do not require high wattage or advanced features for their builds.

Efficiency Ratings

Efficiency is a key factor when choosing a power supply, and here, the MSI MAG A750GLS excels with its 80 PLUS Gold certification, boasting up to 90% efficiency. In contrast, the CORSAIR CX550 holds an 80 PLUS Bronze certification, with efficiency up to 88%. This 2% difference may seem minor, but over time, it can lead to lower energy costs, particularly for those running high-performance systems. The MSI model is better suited for demanding components like high-end GPUs, which might require the extra efficiency.

Power Output

In terms of power output, the MSI MAG A750GLS has a considerable advantage with its 750 watts, compared to the 550 watts offered by the CORSAIR CX550. This 200-watt difference can significantly impact performance, especially for gaming setups that utilize powerful graphics cards or multiple components. The additional wattage of the MSI unit allows for more robust system stability and the capability to support high-energy-demand hardware without risk of power shortages.

Cooling Solutions

Cooling performance is critical for maintaining system longevity and efficiency. The CORSAIR CX550 features a 120mm thermally controlled low-noise fan that operates quietly under low loads, while the MSI MAG A750GLS is equipped with a 135mm Fluid-dynamic bearing fan designed for low noise and enhanced durability. Although both power supplies prioritize quiet operation, the slightly larger fan in the MSI model may offer better airflow and cooling efficiency, particularly under heavy loads.

Modular Design

The design of a power supply can greatly affect cable management and airflow within a PC case. The MSI MAG A750GLS boasts a fully modular design, allowing users to connect only the cables they need for their setup, thus reducing clutter and improving airflow. On the other hand, the CORSAIR CX550 is a non-modular unit, meaning all cables are pre-attached. This can lead to a messier build and potentially obstruct airflow, making the MSI model more appealing for those who prioritize a clean and efficient setup.

Warranty and Durability

Warranty periods can provide peace of mind for consumers, and here the MSI MAG A750GLS stands out with a ten-year warranty, compared to the three-year warranty offered by the CORSAIR CX550. This longer warranty indicates a higher level of confidence in the durability and reliability of the MSI power supply. For users who plan to keep their systems for several years, the extended warranty on the MSI model could be a significant advantage.

Compatibility and Future-Proofing

When considering future upgrades, compatibility is crucial. The MSI MAG A750GLS is equipped with native 12V-2x6 PCIe connectors, making it particularly suitable for upcoming PCIe 5.1 GPUs and next-generation hardware. The CORSAIR CX550, while reliable, may not support the latest technologies to the same extent. If you're looking to future-proof your build, the MSI model offers better compatibility with the latest components, ensuring that your system remains relevant for years to come.

Which should you buy?

Ultimately, the choice between the CORSAIR CX550 and the MSI MAG A750GLS depends largely on your specific needs and budget. If you are looking for a cost-effective, reliable power supply for a mid-range system, the CORSAIR CX550 at $65.99 may suffice. However, for those seeking higher efficiency, more power, a modular design, and a longer warranty, the MSI MAG A750GLS at $89.99 is the superior option. Consider your current and future hardware requirements to make the best decision for your PC build.
