CORSAIR CX550 80 Plus Bronze Non Modular Low-Noise ATX vs MSI MPG A850GS PCIE5, Fully Modular Gaming 850W

Overview of the Power Supplies

In the realm of power supplies, the CORSAIR CX550 and MSI MPG A850GS stand out for their unique features and specifications. The CORSAIR CX550 is an 80 Plus Bronze certified, non-modular unit offering 550 watts of continuous power, while the MSI MPG A850GS is a fully modular power supply rated at 850 watts with an 80 Plus Gold certification. This difference in power capacity and certification directly influences their efficiency and application suitability.

The CORSAIR CX550 is priced at $65.99, making it an attractive choice for budget-conscious consumers. In contrast, the MSI MPG A850GS comes in at $110.99, which is about 68% more expensive than the CORSAIR model. This significant price difference reflects the higher power output and efficiency certifications of the MSI power supply, appealing more to gamers and high-performance PC builders.

Efficiency and Certification

When it comes to efficiency, the MSI MPG A850GS takes the lead with its 80 Plus Gold certification, which guarantees up to 90% operational efficiency. This efficiency means less wasted energy and lower electricity costs over time. In comparison, the CORSAIR CX550, with its 80 Plus Bronze certification, achieves up to 88% efficiency. While both units offer decent efficiency, the MSI’s certification suggests that it will deliver better performance in energy savings.

The difference in efficiency ratings means that, over extended use, the MSI MPG A850GS can lead to lower energy bills than the CORSAIR CX550. This can be a crucial factor for users who plan to run power-hungry systems continuously or for long gaming sessions.

Power Output and Performance

The power output is another critical area where these two power supplies differ significantly. The CORSAIR CX550 offers 550 watts, which is suitable for mid-range builds that do not require excessive power. On the other hand, the MSI MPG A850GS delivers 850 watts, making it ideal for high-end gaming rigs and systems with multiple GPUs.

This difference in wattage means that users planning on running demanding applications or high-performance setups may find the CORSAIR CX550 limiting. In scenarios where maximum power is required, the MSI MPG A850GS provides the necessary headroom, ensuring stable performance even under heavy loads.

Modularity and Cable Management

The CORSAIR CX550 is a non-modular power supply, which means that all cables are fixed to the unit. This can lead to a messier build, especially if not all cables are used. In contrast, the MSI MPG A850GS is fully modular, allowing users to connect only the cables they need for their specific setup. This feature not only helps in maintaining a clean and organized interior but also improves airflow within the case.

For users who prioritize aesthetics and efficient cable management, the MSI MPG A850GS clearly offers an advantage. The ability to customize cable connections can lead to a more streamlined build, which is especially appreciated in the custom PC community.

Cooling Solutions

Cooling is essential in ensuring longevity and performance in power supplies. The CORSAIR CX550 features a 120mm thermally controlled low-noise cooling fan that operates quietly under light loads and ramps up only when necessary. This feature provides a good balance between performance and noise levels.

The MSI MPG A850GS also boasts low-noise operation, but it has additional cooling technologies such as LLC Half Bridge Topology and a semi-digital design, which can contribute to better thermal management. Both units prioritize quiet operation, but the advanced cooling solutions in the MSI model may offer better performance under heavy use.

Warranty and Reliability

Warranty terms can be a deciding factor when purchasing a power supply. The CORSAIR CX550 comes with a three-year warranty, which is standard for many power supplies in its category. However, the MSI MPG A850GS offers a significantly longer 10-year warranty, indicating the manufacturer’s confidence in its reliability and performance.

For consumers who plan on investing in a power supply for the long term, the 10-year warranty on the MSI MPG A850GS provides peace of mind that is hard to overlook. This extended coverage can be particularly appealing to gamers and enthusiasts who want a reliable product that will last through multiple builds.

Price Consideration

The price difference between the two power supplies is quite substantial. At $65.99, the CORSAIR CX550 is about 17% cheaper than the MSI MPG A850GS, which is priced at $110.99. This makes the CORSAIR model an attractive option for budget-conscious consumers or those who do not require high power output or advanced features.

However, the higher price of the MSI MPG A850GS may justify its cost for users seeking superior efficiency, modularity, and performance for gaming or professional use. When considering total cost of ownership, the MSI model may prove to be more economical in the long run due to its efficiency and longer warranty.

Which should you buy?

Choosing between the CORSAIR CX550 and the MSI MPG A850GS ultimately depends on your specific needs and budget. If you are looking for a cost-effective solution for a mid-range build, the CORSAIR CX550 is a solid choice. However, if you require higher wattage, better efficiency, and modularity for a high-performance system, the MSI MPG A850GS is worth the investment. Considering the long-term benefits of efficiency and warranty, the MSI model may provide greater value for serious gamers and PC enthusiasts.
