MSI MAG A650BN PCIE5 III vs CORSAIR SF850

Price Comparison

The MSI MAG A650BN PCIE5 III is significantly more affordable than the CORSAIR SF850, priced at C$104.99 compared to C$279.99. This price difference of C$175 highlights the MAG A650BN as a budget-friendly option for users seeking quality performance without breaking the bank. In contrast, the CORSAIR SF850, while more expensive, offers premium features and power capabilities that may justify its higher price for certain users.

Efficiency Ratings

When it comes to efficiency, the CORSAIR SF850 takes the lead with an 80 PLUS Platinum rating, ensuring higher energy efficiency compared to the MSI MAG A650BN, which has an 80 PLUS Bronze certification. The Platinum rating signifies that the SF850 can achieve over 90% efficiency at typical loads, leading to reduced energy consumption and lower electricity bills. The effectiveness of the MAG A650BN, while respectable, is lower, indicating that users may spend more on energy costs over time.

Form Factor and Compatibility

The MSI MAG A650BN is designed in the ATX format, making it suitable for standard-sized builds, while the CORSAIR SF850 features a compact SFX form factor. This compact design allows the SF850 to fit into smaller cases, making it an ideal choice for power-dense small-form-factor PCs. Additionally, both power supplies comply with their respective ATX standards; the MAG A650BN is ATX 3.1 ready, while the SF850 meets the ATX 3.0 standard, ensuring compatibility with modern systems.

Modular Design

Both the MSI MAG A650BN and the CORSAIR SF850 offer modular designs, but they differ in their approach. The MAG A650BN features embossed jacket modular cables that not only enhance flexibility but also streamline cable management with a sleek appearance. On the other hand, the SF850 boasts fully modular Type-5 Micro-Fit PSU connectors that provide even more compact cabling solutions, essential for maintaining a tidy setup in smaller cases. This difference may influence users who prioritise cable management aesthetics in their builds.

Cooling Solutions

Cooling is another area where the CORSAIR SF850 excels, equipped with a 92mm PWM cooling fan designed for low-noise operation. This fan ensures efficient cooling while maintaining a quiet environment, which is particularly beneficial in compact builds where airflow can be limited. The MSI MAG A650BN does not specify a cooling solution, which raises questions about its thermal management capabilities during intensive use. Users seeking optimal cooling may prefer the established performance of the SF850 in this respect.

Capacitor Quality

The CORSAIR SF850 uses 105°C rated Japanese capacitors, which are known for their reliability and performance under load. This feature provides users with confidence in the longevity and stability of their power supply. The MSI MAG A650BN does not specify the quality or rating of its capacitors, leaving potential buyers uncertain about its reliability over time. For those who value longevity and performance, the superior capacitor quality in the SF850 could be a deciding factor.

Power Delivery Capability

When it comes to power delivery, the MSI MAG A650BN supports PCIe CEM 5.1 and offers a native PCIe 12V-2x6 connector, capable of handling 450W for graphics cards. This makes it an excellent choice for users looking to power modern GPUs efficiently. In comparison, the CORSAIR SF850 is ATX 3.0 compliant and is also PCIe 5.0 ready, designed to handle transient power spikes effectively. Both units offer robust power delivery, but the higher efficiency and premium features of the SF850 may appeal more to enthusiasts and high-performance users.

Which should you buy?

Choosing between the MSI MAG A650BN PCIE5 III and the CORSAIR SF850 ultimately depends on your specific needs and budget. If you are looking for an economical power supply that still delivers solid performance with modern compatibility, the MAG A650BN at C$104.99 is a great choice. However, if you are willing to invest more for higher efficiency, superior cooling, and a compact design, the CORSAIR SF850 at C$279.99 offers features that could significantly enhance your system's performance and longevity. Consider your priorities in terms of budget, efficiency, and space when making your decision.
