MSI MAG A750GL PCIE5 Power Supply Unit vs CORSAIR CX650 80 PLUS Bronze Non Modular Low-Noise ATX 650 Watt Power Supply - U

Price Comparison

When comparing the prices of the MSI MAG A750GL PCIE5 Power Supply Unit and the CORSAIR CX650, the difference is quite significant. The MSI unit is priced at £74.99, while the Corsair model is more budget-friendly at £44.99. The £30 difference may play a crucial role for consumers on a tight budget or those looking for basic functionality. While both power supplies offer reliable performance, the higher price of the MSI unit can be justified by its advanced features, such as 80 PLUS Gold certification and PCI-E 5.0 support, which may appeal to users with high-end systems.

Efficiency Ratings

The MSI MAG A750GL boasts an 80 PLUS Gold certification, indicating an operational efficiency of up to 90%. This high efficiency reduces energy consumption and heat generation, making it suitable for power-hungry components. In contrast, the CORSAIR CX650 is rated at 80 PLUS Bronze, with a maximum efficiency of 88%. While both power supplies offer solid efficiency, the additional 2% in efficiency from the MSI unit, especially under heavy loads, can lead to lower energy costs over time. For users prioritising energy efficiency, the MSI model presents a clear advantage.

Modular Design

The MSI MAG A750GL features a fully modular design, allowing users to connect only the cables they need, which helps reduce clutter and improve airflow within the case. On the other hand, the CORSAIR CX650 is a non-modular power supply, meaning all cables are permanently attached. This can lead to excess cables taking up space and potentially obstructing airflow. The modular capability of the MSI unit is particularly beneficial for those who value clean builds and optimal cable management, making it a better choice for enthusiasts aiming for a tidy setup.

Power Output

In terms of power output, the MSI MAG A750GL delivers a robust 750 watts, while the CORSAIR CX650 provides 650 watts. This 100-watt difference can significantly impact performance, especially for high-end gaming rigs or workstations with demanding components. The MSI model is equipped to handle more substantial power excursions, supporting advanced GPUs and CPUs without compromising performance. Users with high-performance requirements will find the MSI unit more capable, providing a greater buffer for future upgrades.

Cooling Solutions

Cooling performance is another area where the two products differ. The MSI MAG A750GL features a 120mm fluid dynamic bearing fan that is designed to provide reliable cooling, while the CORSAIR CX650 utilises a thermally controlled 120mm fan that optimises noise levels based on load. The MSI's fan design focuses on maintaining cooling efficiency, even under heavy demand, which could be crucial in scenarios where sustained performance is necessary. Although the Corsair model is quieter during low loads, it may not provide the same cooling efficiency when under heavy stress, making MSI a better fit for high-performance applications.

Compatibility with Modern Hardware

For those looking to future-proof their systems, the MSI MAG A750GL excels with its native PCI-E 5.0 support. It includes a 16-pin connector capable of delivering up to 450 watts to the latest GPUs, accommodating demanding graphics cards from both NVIDIA and AMD. In contrast, the CORSAIR CX650, while reliable, does not offer the same level of compatibility with the newest hardware standards. Users planning to build or upgrade to the latest technology will find that the MSI unit better meets their needs, especially for high-performance gaming or professional workloads.

Build Quality and Warranty

In terms of build quality, the MSI MAG A750GL features a full-bridge LLC with a DC-to-DC converter and active PFC design, ensuring robust output and protection against various electrical issues. Furthermore, it comes with a commendable 7-year limited warranty, reflecting the manufacturer’s confidence in its durability. The CORSAIR CX650 offers a solid build as well, but without the same level of advanced protective features or extended warranty. For users concerned about longevity and reliability, the MSI model presents a stronger case with its superior warranty and enhanced protective design.

Which should you buy?

Choosing between the MSI MAG A750GL and the CORSAIR CX650 ultimately depends on your specific needs and budget. If you are looking for a power supply that offers high efficiency, modular design, and compatibility with cutting-edge hardware, the MSI MAG A750GL is the superior choice, albeit at a higher price of £74.99. However, if you are on a budget and require a reliable power supply for a mid-range system, the CORSAIR CX650 at £44.99 provides adequate performance with lower efficiency and fewer features. For high-performance users and gamers, the investment in the MSI model is likely to pay off in the long run.
