CORSAIR RM850e Fully Modular Low-Noise ATX Power vs MSI MAG A650BN, Non-Modular Compact 650W Power

Price Comparison

When comparing the prices of the CORSAIR RM850e and the MSI MAG A650BN, the MSI power supply is significantly more affordable. The CORSAIR RM850e is priced at $94.99, while the MSI MAG A650BN is available for $59.99. This makes the MSI option about 37% cheaper than the CORSAIR model. For budget-conscious consumers, this price difference may be a crucial deciding factor, especially for those who are looking to save on costs without sacrificing too much in terms of performance.

Power Output

In terms of power output, the CORSAIR RM850e clearly stands out with its 850W capacity compared to the MSI MAG A650BN’s 650W. This difference of 200W means that the CORSAIR model is better suited for high-performance builds, particularly those that require additional power for components like powerful graphics cards. If you're planning to run a demanding gaming setup or a workstation, the extra wattage provided by the CORSAIR RM850e could be invaluable in ensuring stability and performance.

Modularity

The modularity of the power supply is another key differentiator between the two products. The CORSAIR RM850e features a fully modular design, allowing users to connect only the cables necessary for their system, which can lead to a cleaner and more organized build. In contrast, the MSI MAG A650BN is a non-modular unit, which means all cables are permanently attached. This can make cable management more challenging, especially in compact cases where space is limited. For those who prioritize aesthetics and ease of installation, the modularity of the CORSAIR RM850e is a significant advantage.

Efficiency Ratings

When it comes to efficiency, the CORSAIR RM850e boasts Cybenetics Gold certification, indicating a higher level of energy efficiency compared to the MSI MAG A650BN, which is certified with the 80 PLUS Bronze rating. This means that the CORSAIR model is likely to consume less power and generate less heat, resulting in potentially lower electricity bills over time. For users who are conscious of energy consumption and environmental impact, the superior efficiency of the CORSAIR RM850e makes it a more appealing choice.

Noise Levels

Noise levels are an important consideration for many users, especially those building a PC for gaming or media consumption. The CORSAIR RM850e is designed with a 120mm rifle bearing fan and a specially calculated fan curve, which helps to keep noise levels down even under full load. In comparison, while the MSI MAG A650BN features a low-noise fan, it does not specify the same level of advanced noise-reduction technology. Thus, users looking for a quieter power supply may find the CORSAIR RM850e to be the better option.

Build Quality and Components

The build quality and components used in a power supply can significantly impact its performance and longevity. The CORSAIR RM850e utilizes 105°C-rated capacitors, which are designed to withstand higher temperatures and provide reliable power delivery. This is particularly important for ensuring stability during demanding tasks. The MSI MAG A650BN, while a solid choice, does not highlight similar high-temperature rated components. For those interested in long-term reliability and performance, the superior components in the CORSAIR model are a notable advantage.

Warranty and Support

Both power supplies come with warranties that reflect their manufacturers' confidence in their products. The CORSAIR RM850e is backed by a seven-year warranty, indicating long-term reliability and support. On the other hand, the MSI MAG A650BN offers a five-year warranty. This difference in warranty duration may be important for consumers looking for peace of mind regarding their investment. A longer warranty often suggests that a manufacturer stands behind their product for an extended period, which can be a deciding factor for some buyers.

Which should you buy?

Ultimately, the choice between the CORSAIR RM850e and the MSI MAG A650BN comes down to your specific needs and budget. If you are looking for a high-capacity, fully modular power supply with superior efficiency and quieter operation, the CORSAIR RM850e is worth the investment at $94.99. However, if you are on a tighter budget and need a more compact power supply for a less demanding build, the MSI MAG A650BN at $59.99 offers solid performance and decent efficiency. Your decision should reflect your priorities, whether they lean towards performance and features or cost-effectiveness.
