MSI MAG A750GL PCIE5 Power Supply Unit vs CORSAIR SF850

Power Efficiency

When it comes to power efficiency, the MSI MAG A750GL excels with its 80 PLUS Gold certification, while the CORSAIR SF850 takes it a step further with an impressive 80 PLUS Platinum rating. The MSI power supply achieves up to 90% efficiency, making it an excellent choice for high-end GPUs and CPUs that demand significant power. In contrast, the Corsair model offers even greater efficiency, which is crucial for systems that require reliable and stable power delivery, particularly in compact spaces. The difference in efficiency ratings may lead to lower energy consumption over time with the Corsair, justifying its higher price of £149.99 compared to the MSI's £74.99.

Modular Design

Both the MSI MAG A750GL and the CORSAIR SF850 feature fully modular designs, but they cater to different types of builds. The MSI unit offers an ATX 3.0 fully modular setup, which is beneficial for reducing clutter and improving airflow in larger cases. It comes with flat black cables that not only look sleek but also enhance airflow. On the other hand, the Corsair unit employs Type-5 micro-fit PSU connectors that are designed to save space in small form-factor builds. This makes the Corsair a better option for compact setups where every inch counts, despite its higher price.

Cooling Solutions

Cooling performance is another area where these two power supplies differ significantly. The MSI MAG A750GL is equipped with a 120mm fluid dynamic bearing fan that provides reliable cooling while maintaining a balance between performance and noise levels. The Corsair SF850, however, features a slightly smaller 92mm PWM cooling fan that also prioritises low-noise operation but may not offer the same cooling capacity as the larger fan in the MSI model. Both fans utilise fluid dynamic bearing technology, ensuring durability and quieter operation, but the MSI's larger fan may help it run cooler under heavy loads.

Compatibility and Future-Proofing

In terms of compatibility and future-proofing, the MSI MAG A750GL supports PCIe 5.0 GPUs, providing up to 450W of power to these next-generation graphics cards. This makes it highly suitable for users looking to invest in high-performance gaming rigs. Conversely, the Corsair SF850 is ATX 3.1 compliant and ready for the PCIe 5.1 platform, which positions it as a more future-proof option. This compliance ensures that the Corsair will handle transient power spikes effectively, making it a smart choice for those anticipating future upgrades in their systems.

Component Quality

Component quality is an essential consideration when evaluating power supplies. The MSI MAG A750GL is designed with a full-bridge LLC with a DC-to-DC converter and active PFC, ensuring robust output and various protections such as OVP, OCP, and OTP. It also boasts a long 7-year limited warranty, which speaks volumes about its durability and reliability. Meanwhile, the Corsair SF850 stands out with its 105°C rated Japanese capacitors, which are known for their high quality and reliability. This aspect may contribute to the longevity of the power supply, making the Corsair a solid investment for users who prioritise component quality.

Size and Form Factor

The form factor of these power supplies is another distinguishing feature. The MSI MAG A750GL comes in a standard ATX size, measuring 140mm in length, which is suitable for most cases but may not fit in compact builds. In contrast, the CORSAIR SF850 is designed as an SFX power supply, making it much more suitable for small-form-factor PCs. This compact design is particularly appealing for users looking to build powerful yet space-efficient systems. However, the trade-off is that the Corsair unit is priced significantly higher than the MSI, making it essential for buyers to consider their specific build requirements.

Price Comparison

Price is a crucial factor when comparing the MSI MAG A750GL and the CORSAIR SF850. The MSI unit is currently priced at £74.99, making it a more budget-friendly option without compromising on essential features. In contrast, the Corsair SF850 retails for £149.99, reflecting its premium features and high-quality components. While the higher price of the Corsair may be justified for users seeking enhanced efficiency and compact design, the MSI provides excellent value for those who need solid performance without breaking the bank.

Which should you buy?

Ultimately, the choice between the MSI MAG A750GL and the CORSAIR SF850 depends on your specific needs and budget. If you are looking for a cost-effective power supply with excellent power efficiency and solid performance, the MSI model is a fantastic choice at £74.99. However, if you require a compact, high-efficiency power supply with top-tier components and future-proofing capabilities, the Corsair SF850 is worth the investment at £149.99. Consider your build requirements and long-term plans to determine which power supply aligns best with your expectations.
