MSI MAG A850GL PCIE5 White vs CORSAIR CX550 80 Plus Bronze Non Modular Low-Noise ATX 550 Watt Power Supply - N

Price Comparison

The MSI MAG A850GL PCIE5 White is priced at C$199.99, while the CORSAIR CX550 80 Plus Bronze is significantly more affordable at C$84.99. This represents a difference of C$115.00. For budget-conscious consumers, the lower price point of the CORSAIR model makes it a compelling option, especially for those who do not require high-end specifications. On the other hand, the MSI power supply commands a premium due to its advanced features, such as being ATX 3.1 ready and its full modular design, which may justify the higher cost for users needing these capabilities.

Efficiency Ratings

The CORSAIR CX550 is 80 PLUS Bronze certified, showcasing operational efficiency of up to 88%. This means it generates less heat and reduces energy costs, making it a more economical choice over time. In contrast, the MSI MAG A850GL does not specify an efficiency rating, which might raise concerns for users who prioritise energy efficiency. The increased efficiency of the CORSAIR model can lead to better long-term savings, especially in systems that demand continuous power delivery.

Cooling Performance

Cooling performance is essential for ensuring the longevity and reliability of power supplies. The CORSAIR CX550 features a 120mm thermally controlled low-noise cooling fan that adjusts its speed based on the load, providing quieter operation during lower loads. While the MSI MAG A850GL also includes a 120mm Fluid Dynamic Bearing fan, it lacks specific mention of noise control features. Users looking for a quieter system might prefer the CORSAIR model, which is designed specifically to minimise noise during less intensive tasks.

Design and Build Quality

When it comes to design, the MSI MAG A850GL boasts a full modular design with flat cables, which can facilitate better airflow within the PC case and enhance overall aesthetics. It is also noted for its industrial-level protection features, including OVP, OCP, OPP, OTP, SCP, and UVP, indicating robust safety measures. In comparison, the CORSAIR CX550 features a compact 125mm length and black sleeving, designed to fit seamlessly into most modern PC cases. While both models focus on design, the MSI’s modular design and advanced protective features may appeal more to high-end users.

Power Output

The MSI MAG A850GL delivers a substantial power output, which is crucial for high-performance builds equipped with multiple components. Although the exact wattage is not specified, the naming suggests it is capable of providing ample power to demanding systems. The CORSAIR CX550, on the other hand, is rated at 550 watts of continuous power. This guarantees reliable performance for standard builds, but may fall short for users with high-performance needs. For those building a system with high-end graphics cards or multiple components, the MSI model may be more suitable.

Modularity

The modular design of the MSI MAG A850GL allows users to connect only the cables they need, which can greatly enhance cable management and airflow within the case. This full modularity is a distinct advantage for builders who prefer a clean and efficient setup. Conversely, the CORSAIR CX550 is a non-modular power supply, meaning all cables are permanently attached. While this may simplify installation for some users, it can lead to excess cables cluttering the system, potentially affecting airflow. For those who value a tidy build, the modularity of the MSI power supply is a significant benefit.

Safety Features

Safety is a paramount consideration when selecting a power supply. The MSI MAG A850GL is equipped with an active PFC design and multiple protective features, including overvoltage protection (OVP), overcurrent protection (OCP), and more. This industrial-grade protection ensures that the power supply can safeguard both itself and the components within the PC. The CORSAIR CX550, while reliable, does not specify similar extensive safety features, which may concern users prioritising protection for their hardware. The extensive safety measures of the MSI model may provide peace of mind for users building high-end systems.

Which should you buy?

Choosing between the MSI MAG A850GL PCIE5 White and the CORSAIR CX550 80 Plus Bronze ultimately comes down to your specific needs and budget. If you require a power supply that is ATX 3.1 ready, modular, and equipped with advanced safety features, the MSI model at C$199.99 might be worth the investment. However, if you are looking for a budget-friendly option that still provides solid performance and efficiency, the CORSAIR CX550 at C$84.99 is an excellent choice. Each power supply serves different user bases, making the decision heavily reliant on individual requirements and financial considerations.
