CORSAIR CX650 80 PLUS Bronze Non Modular Low-Noise ATX 650 Watt Power Supply - U vs MSI MAG A1000GLS PCIE5 Power Supply Unit

Price Comparison

When comparing the prices of the CORSAIR CX650 and the MSI MAG A1000GLS, there is a significant difference. The CORSAIR CX650 is priced at £44.99, while the MSI MAG A1000GLS comes in at a much higher £104.99. This price disparity reflects the different certifications and capabilities of these power supplies. The CORSAIR model is an 80 PLUS Bronze certified unit with up to 88% efficiency, making it a budget-friendly option for those who need reliable power without breaking the bank. In contrast, the MSI MAG A1000GLS, being 80 PLUS Gold certified, offers up to 90% efficiency, justifying its higher price for users with more demanding power requirements.

Efficiency Ratings

The efficiency ratings of the two power supplies highlight their operational effectiveness. The CORSAIR CX650 is 80 PLUS Bronze certified, achieving up to 88% efficiency, which is suitable for standard gaming and productivity setups. On the other hand, the MSI MAG A1000GLS boasts an 80 PLUS Gold certification with an impressive efficiency of up to 90%. This higher efficiency is particularly beneficial for users with high-performance components, as it generates less heat and can lead to lower energy costs over time. Thus, while both units are efficient, the MSI MAG A1000GLS takes the edge for those prioritising performance.

Power Output

In terms of power output, the CORSAIR CX650 delivers a continuous power rating of 650 watts, which is adequate for most mid-range PC builds. However, the MSI MAG A1000GLS stands out with its ability to deliver up to 600 watts specifically through its native 12V-2x6 PCIe connectors, making it particularly suited for high-demand hardware such as the latest GPUs. This capability is crucial for gamers and content creators who require stable and robust power delivery for their systems. While the CORSAIR model offers a higher continuous power rating, the MSI's targeted high-output connectors provide flexibility for modern hardware.

Design and Size

The physical design and size of the power supplies are important considerations for PC builders. The CORSAIR CX650 features a compact casing measuring 125mm in length, which ensures compatibility with most modern PC cases. Its low-noise cooling system is designed to operate quietly, making it an appealing choice for users who prioritise a silent working environment. Conversely, the MSI MAG A1000GLS has a slightly larger footprint with dimensions of 150mm in length and width, but it maintains a compact ATX form factor. This design not only fits comfortably in most cases but also allows for better cable management and airflow, which can be advantageous in high-performance builds.

Cooling Solutions

Both power supplies incorporate advanced cooling solutions to enhance performance and longevity. The CORSAIR CX650 uses a 120mm thermally controlled low-noise fan that adjusts its speed based on the load, ensuring quiet operation during less intensive tasks. This feature is ideal for users looking for a balance of performance and silence. In contrast, the MSI MAG A1000GLS is equipped with a 135mm Fluid-dynamic bearing fan, designed for durability and maintaining a low sound level comparable to a peaceful night. This fan not only enhances cooling efficiency but also ensures that the unit operates quietly, even under load, making it suitable for high-performance gaming or content creation environments.

Compatibility and Connectivity

Compatibility is a critical factor when choosing a power supply, especially for users planning to upgrade their components. The CORSAIR CX650 is designed to work seamlessly with most standard builds, delivering its full rated wattage without issues. However, the MSI MAG A1000GLS offers additional advantages with its native 12V-2x6 PCIe connectors, which are designed to support the latest PCIe 5.1 GPUs. This makes the MSI unit particularly well-suited for users looking to future-proof their systems and accommodate the latest hardware advancements. While both units are compatible with a wide range of systems, the MSI MAG A1000GLS provides specific features that cater to modern gaming and high-performance setups.

Noise Levels

Noise levels play a significant role in the overall user experience of a power supply. The CORSAIR CX650 is designed with low-noise operation in mind, as its fan only ramps up under heavy stress, making it a great choice for quieter builds. The MSI MAG A1000GLS, with its advanced fan design, aims to keep noise levels at a minimum, maintaining a sound level that is as low as a peaceful night. For users who are sensitive to noise or who work in quiet environments, both power supplies offer features that help mitigate sound, although the MSI model's design may provide a slight edge in ensuring ultra-quiet operation under load.

Which should you buy?

Choosing between the CORSAIR CX650 and the MSI MAG A1000GLS ultimately depends on your specific needs and budget. If you are looking for an affordable, reliable power supply for a standard build, the CORSAIR CX650 at £44.99 offers excellent value with its 80 PLUS Bronze efficiency and compact design. However, if you are building a high-performance system and need the latest technology and higher efficiency, the MSI MAG A1000GLS at £104.99 provides superior power delivery and features designed for modern hardware, making it a worthy investment.
