MSI MAG A750GL PCIE5 Power Supply Unit vs JUSTOP Black 750W PSU

Price Comparison

The MSI MAG A750GL PCIE5 Power Supply Unit is priced at £74.99, while the JUSTOP Black 750W PSU is significantly more affordable at £32.95. This represents a difference of £42.04, making the JUSTOP option appealing for those on a budget. However, the MSI unit justifies its higher price with advanced features tailored for high-performance systems. If you're looking for a cost-effective solution for basic needs, the JUSTOP may suffice, but for users requiring top-tier performance, the investment in the MSI power supply could be worthwhile.

Efficiency Ratings

When it comes to energy efficiency, the MSI MAG A750GL is an 80 PLUS Gold-certified power supply, which indicates it operates at up to 90% efficiency. This level of efficiency is particularly beneficial for high-demand systems, as it reduces energy consumption and heat generation. In contrast, the JUSTOP Black 750W PSU does not specify an efficiency rating but does include Power Factor Control (PFC) and several protective features. While the JUSTOP may be adequate for standard tasks, the MSI’s certification offers a clear advantage for gamers or professionals using high-end GPUs and CPUs, making it a more efficient choice overall.

Modular Design

The MSI MAG A750GL features an ATX 3.0 fully modular design, which allows users to connect only the cables necessary for their build. This not only reduces clutter but also enhances airflow within the case. The JUSTOP Black PSU, on the other hand, does not mention a modular design, suggesting that it may come with fixed cables. For users who prioritise neatness and airflow, the MSI power supply's modularity is a significant benefit, especially in larger builds where cable management can become a challenge.

GPU Compatibility

One of the standout features of the MSI MAG A750GL is its native PCI-E 5.0 GPU support, enabling it to deliver up to 450W of power to high-performance graphics cards. This feature is particularly relevant for users investing in the latest NVIDIA and AMD GPUs. The JUSTOP Black PSU provides a single 8-pin (6+2) PCI-E connector, which may suffice for many standard graphics cards but lacks the cutting-edge support of the MSI unit. If you're planning to utilise the newest generation of graphics cards, the MSI option is clearly the superior choice.

Cooling Solutions

The MSI power supply is equipped with a 120mm fluid dynamic bearing fan, designed for reliable cooling performance, which is essential for maintaining system stability during demanding tasks. In comparison, the JUSTOP Black PSU also features a 120mm cooling fan, but lacks specific details about the type of fan used. While both units provide cooling solutions, the MSI's use of fluid dynamic bearing technology often results in quieter and more efficient operation. For users concerned about noise levels and thermal performance, the MSI power supply has a clear edge.

Build Quality and Durability

The MSI MAG A750GL boasts a durable design featuring a full-bridge LLC with a DC-to-DC converter and active PFC. This construction not only enhances the reliability of power delivery but also includes multiple protections such as Over Current Protection (OCP) and Over Voltage Protection (OVP). Conversely, the JUSTOP Black PSU provides essential protections, including thermal overload cut-off and short circuit protection, but lacks the advanced features of the MSI model. For those prioritising longevity and robust performance, the MSI power supply stands out as a more reliable option.

Safety Certifications

Safety is paramount when it comes to power supplies, and both the MSI MAG A750GL and the JUSTOP Black PSU come with safety certifications. The JUSTOP model is UKCA, CE, FCC, UL, and TUV Electrical Safety Certified, ensuring it meets various international safety standards. While the MSI unit does not specify its certifications, the brand’s reputation for quality typically implies adherence to stringent safety protocols. For users who prioritise safety certifications, both options provide adequate reassurance, but the broader certification range of the JUSTOP may appeal to those concerned with compliance in various regions.

Which should you buy?

The choice between the MSI MAG A750GL PCIE5 Power Supply Unit and the JUSTOP Black 750W PSU ultimately hinges on your specific needs and budget. If you require a power supply with high efficiency, advanced modularity, and robust support for modern graphics cards, the MSI unit at £74.99 is the better investment. However, for users with basic power requirements seeking a budget-friendly option, the JUSTOP Black PSU at £32.95 offers an impressive value while ensuring fundamental safety and performance standards. Consider your system's demands carefully to determine which power supply aligns best with your setup.
