MSI MAG A750GL PCIE5 Power Supply Unit vs Gigabyte UD850GM PG5 ICE 80 Plus Gold Fully Modular 850w PCIe 5.0 White Power Su

Price Comparison

The MSI MAG A750GL PCIE5 Power Supply Unit is priced at £74.99, significantly lower than the Gigabyte UD850GM PG5 ICE, which retails for £99.61. This makes the MSI option more appealing for budget-conscious consumers seeking a quality power supply. However, the higher price of the Gigabyte unit may reflect additional features and superior specifications, which could be worth the investment for some users. When comparing value for money, the MSI model offers an attractive entry point into the 80 PLUS Gold certified power supply market.

Certification and Efficiency

Both power supplies are 80 PLUS Gold certified, which indicates high energy efficiency and reduced energy consumption. The MSI MAG A750GL boasts an efficiency of up to 90%, making it an excellent choice for users with high-end GPUs and CPUs. On the other hand, the Gigabyte UD850GM PG5 also carries the 80 PLUS Gold certification, ensuring reliable energy efficiency. While both units excel in efficiency, the MSI's specific claim of up to 90% may give it a slight edge for those prioritising power conservation and heat reduction.

Design and Modularity

The MSI MAG A750GL features an ATX 3.0 fully modular design that allows for easy cable management and improved airflow. It is compact, measuring only 140mm in length, which aids in fitting into smaller cases. Conversely, the Gigabyte UD850GM PG5 also presents a fully modular design but is classified as Intel ATX 3.1 ready, suggesting it can accommodate more advanced configurations. The Gigabyte unit’s compact size is also highlighted, although specific dimensions are not provided. Overall, both designs focus on modularity and compactness, appealing to users who value organisation and airflow.

Cooling Solutions

When it comes to cooling, the MSI MAG A750GL is equipped with a 120mm fluid dynamic bearing fan that offers reliable cooling performance. This design is essential for maintaining stability during intense gaming or heavy workloads. The Gigabyte UD850GM PG5, meanwhile, utilises a 120mm smart hydraulic bearing fan, which is optimized for thermal solutions. While both fans are similar in size, the term "smart" in the Gigabyte model suggests enhanced performance based on thermal demands. Thus, users can expect effective cooling from either power supply, but the Gigabyte may have a slight advantage in adapting to varying thermal conditions.

Power Capacity

The MSI MAG A750GL provides a powerful single-rail design that can deliver ample power to the system, addressing the needs of high-performance components. It is particularly noteworthy for its capability to support a PCIe 5.0 GPU with a native 16-pin connector that can provide up to 450W of power. In contrast, the Gigabyte UD850GM PG5 offers an 850W capacity, which is higher than the MSI model's specified output, making it potentially more suitable for users with multiple high-demand components. Therefore, if maximum output is a critical factor, the Gigabyte may be the better choice.

Component Quality

The MSI MAG A750GL is designed with a full-bridge LLC and a DC-to-DC converter, ensuring robust output stability and protection features. It boasts a 7-year limited warranty, which indicates confidence in its longevity and reliability. The Gigabyte UD850GM PG5, on the other hand, is built with 100% Japanese capacitors, known for their high quality and long lifespan. It also includes a range of protection features such as OVP (Over Voltage Protection), OPP (Over Power Protection), and more. While both power supplies exhibit high-quality components, the specific mention of Japanese capacitors in the Gigabyte model may appeal to those prioritising long-term durability.

Compatibility and Future-Proofing

The MSI MAG A750GL is designed to support PCIe 5.0, catering to the latest generation of graphics cards from both NVIDIA and AMD. Its advanced ATX 3.0 compliance ensures it can accommodate future hardware upgrades effectively. Similarly, the Gigabyte UD850GM PG5 is also PCIe Gen 5.1 ready, which may offer slightly greater future-proofing in terms of upcoming technology advancements. Both models are equipped to handle the demands of contemporary systems, but the Gigabyte's alignment with the latest standards might provide an edge for users who frequently upgrade their components.

Which should you buy?

Choosing between the MSI MAG A750GL PCIE5 Power Supply Unit and the Gigabyte UD850GM PG5 ICE comes down to specific needs and budget. The MSI model is more affordable at £74.99, offering excellent efficiency and a compact design, making it ideal for budget-conscious gamers or general users. Conversely, the Gigabyte unit, priced at £99.61, provides a higher power capacity and advanced features that may appeal to enthusiasts or those planning extensive upgrades. Ultimately, if you prioritise cost and efficiency, the MSI is the better choice; however, if you seek higher output and the latest technology readiness, the Gigabyte may be worth the additional investment.
