CORSAIR RM750x Shift Fully Modular ATX Power vs MSI MAG A650BN, Non-Modular Compact 650W Power

Overview

The CORSAIR RM750x Shift and the MSI MAG A650BN are two power supplies that cater to different segments of the market. The CORSAIR unit is priced at $79.99, while the MSI model comes in at a more economical $59.99, making it about 25% cheaper than the CORSAIR option. Each power supply has its own set of features and capabilities, which can influence your decision based on your specific needs and budget.

Performance

In terms of performance, the CORSAIR RM750x Shift offers 750W of power, compared to the MSI MAG A650BN's 650W. This difference of 100W may not seem significant for casual users, but for high-performance builds or gaming rigs, the extra power can make a difference. The CORSAIR unit is also 80 Plus Gold certified, which means it has higher energy efficiency compared to the MSI's 80 Plus Bronze certification. This translates to less energy waste and potentially lower electricity bills over time.

Design and Build Quality

The design of the CORSAIR RM750x Shift is particularly noteworthy, featuring a side cable interface that simplifies cable management. This innovative design allows for easier access to connections, making it a great option for those who value a clean and organized PC build. The MSI MAG A650BN, on the other hand, is a non-modular power supply, meaning that all cables are pre-attached. While this may slightly reduce complexity, it can also lead to cluttered setups. The build quality of the CORSAIR, utilizing 100% 105°C-rated Japanese electrolytic capacitors, suggests a focus on long-term reliability and performance.

Noise Level

When it comes to noise levels, the CORSAIR RM750x Shift shines with its 140mm fluid dynamic bearing fan, which operates quietly, especially in low-load situations thanks to its Zero RPM mode. This ensures that the power supply remains virtually silent during less intensive tasks. The MSI MAG A650BN advertises a low-noise fan, but does not specify features like Zero RPM mode, which could mean it might be noisier under similar conditions. If a quiet computing experience is essential for you, the CORSAIR could be the better choice.

Warranty and Support

Warranty is an important factor for any hardware purchase. The CORSAIR RM750x Shift comes with a robust ten-year warranty, reflecting confidence in its durability and performance. In contrast, the MSI MAG A650BN offers a five-year warranty. While five years is still respectable, the longer warranty period of the CORSAIR provides added peace of mind for users who expect their power supply to last through multiple system upgrades.

Compatibility

The CORSAIR RM750x Shift is certified for Intel ATX 3.1 and supports the PCIe Gen 5.1 platform, making it a future-proof choice for users looking to build cutting-edge systems. Meanwhile, the MSI MAG A650BN is less specific in terms of compatibility but is still a standard ATX power supply suitable for most builds. If you're planning to use the latest hardware, the CORSAIR's modern certifications may offer a significant advantage.

Price Comparison

The price difference between these two power supplies is notable, with the CORSAIR RM750x Shift at $79.99 and the MSI MAG A650BN at $59.99. This makes the MSI option approximately 25% less expensive, which can be appealing for budget-conscious consumers. However, it’s important to evaluate whether the additional features and performance of the CORSAIR justify the higher price for your specific needs.

Which should you buy?

Ultimately, the choice between the CORSAIR RM750x Shift and the MSI MAG A650BN boils down to your specific requirements and budget. If you prioritize performance, energy efficiency, and future-proofing, the CORSAIR RM750x Shift is the superior option, albeit at a higher price. However, if you're looking for a more budget-friendly power supply that still meets basic needs, the MSI MAG A650BN is a solid choice. Consider your system requirements and personal preferences when making your decision.
