CORSAIR CX550 80 Plus Bronze Non Modular Low-Noise ATX vs MSI MAG A750BE, Semi-Modular Compact 750W ATX

Overview of the Power Supplies

In this comparison, we will examine two compelling power supply options: the CORSAIR CX550 and the MSI MAG A750BE. Both units are 80 PLUS Bronze certified, indicating good energy efficiency, but they differ significantly in wattage and design features. The CORSAIR CX550 is priced at $65.99, while the MSI MAG A750BE comes in at $69.99, making it about 6% more expensive.

Efficiency and Performance

Both the CORSAIR CX550 and MSI MAG A750BE are designed to deliver high operational efficiency. The CORSAIR model boasts an impressive operational efficiency of up to 88%, which not only reduces heat generation but also lowers energy costs. On the other hand, the MSI MAG A750BE is similarly 80 PLUS Bronze certified, ensuring high efficiency, although specific efficiency percentages are not disclosed. This efficiency is crucial for users looking to minimize their energy bills over time, making both options strong contenders in this category.

Design and Form Factor

When it comes to design, the CORSAIR CX550 is built with a compact casing of 125mm, allowing for an easy fit in most modern PC cases. Its black sleeved cables and powder-coated casing contribute to a sleek aesthetic. In contrast, the MSI MAG A750BE is a semi-modular power supply, which typically allows for neater cable management by letting users connect only the cables they need. This feature can make for a cleaner build, although the exact dimensions of the MSI model are not provided. Both designs target ease of installation and aesthetics, catering to different user preferences.

Noise Levels

Noise performance is an important factor for many users, and both power supplies are engineered for low noise. The CORSAIR CX550 features a 120mm thermally controlled fan that operates quietly at low loads, only ramping up under heavy stress. Meanwhile, the MSI MAG A750BE also incorporates a low-noise 120mm fan, although specific noise levels are not mentioned. Both products aim to provide a quieter computing experience, making them suitable for users who prioritize a peaceful environment.

Warranty and Reliability

Reliability is a critical aspect of any power supply, and both manufacturers back their products with warranties. The CORSAIR CX550 comes with a three-year warranty, which offers decent coverage for users. In contrast, the MSI MAG A750BE shines with a more robust five-year warranty, providing additional peace of mind for the investment. This extended warranty may be appealing to users who plan to keep their systems for a longer period.

Protection Features

Protection features are crucial for safeguarding your components from power fluctuations. The CORSAIR CX550 ensures full continuous power delivery, which guarantees that it can perform under load without issues. The MSI MAG A750BE, on the other hand, boasts a range of industrial-level protections, including Over Voltage Protection (OVP), Over Current Protection (OCP), Over Power Protection (OPP), Over Temperature Protection (OTP), and Short Circuit Protection (SCP). This array of protections may give the MSI model an edge in terms of safeguarding critical components.

Price Comparison

The CORSAIR CX550 is priced at $65.99, making it a more budget-friendly option compared to the MSI MAG A750BE, which retails for $69.99. This price difference of $4 may not seem significant, but it represents about a 6% increase in cost for the MSI unit. For users on a tight budget, the CORSAIR model may be the more attractive choice, particularly if they do not require the additional wattage offered by the MSI power supply.

Which should you buy?

Choosing between the CORSAIR CX550 and the MSI MAG A750BE ultimately depends on your specific needs. If you are looking for a more affordable option with solid performance and a reliable warranty, the CORSAIR CX550 could be the better choice. However, if you prioritize higher wattage, extended warranty coverage, and additional protective features, the MSI MAG A750BE may be worth the extra cost. Both power supplies offer excellent value within their respective strengths, so consider what aspects are most important for your build before making a decision.
