MSI MAG A1000GLS 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 A1000GLS PCIE5 Power Supply Unit is priced at £104.99, while the Gigabyte UD850GM PG5 ICE is more affordable at £99.61. This price difference of £5.38 may influence budget-conscious consumers looking to optimise their build without compromising on quality. While both units are 80 PLUS Gold certified, the Gigabyte model offers a slightly lower price point, making it an attractive option for those who seek efficiency at a reduced cost.

Efficiency and Certification

Both power supplies boast an 80 PLUS Gold certification, ensuring high efficiency with up to 90% energy utilisation. This certification indicates that both models are designed to reduce energy waste, making them suitable for high-performance gaming rigs or workstations. However, the MSI unit supports native 12V-2x6 PCIe connectors, crucial for PCIe 5.1 GPUs, while the Gigabyte also claims compatibility with PCIe Gen 5.1. This positions both units as reliable choices for modern configurations, though the MSI model explicitly emphasises its capability to handle demanding hardware.

Design and Modularity

The Gigabyte UD850GM PG5 ICE features a fully modular design, allowing users to connect only the cables they need for their build. This can lead to improved cable management and airflow within the case. In contrast, the MSI MAG A1000GLS, while not explicitly modular, has a compact size that also aids in easy installation and space management. The design focus of both PSUs caters to enhancing system organisation, with the MSI being 150 mm long and wide, making it compatible with most cases.

Cooling Solutions

Cooling is a critical factor in power supply performance, and both units employ advanced fan technologies. The MSI MAG A1000GLS is equipped with a 135 mm fluid-dynamic bearing fan, designed for low noise operation, maintaining sound levels comparable to a peaceful night. Meanwhile, the Gigabyte UD850GM PG5 ICE utilises a 120 mm smart hydraulic bearing fan, which is optimised for thermal performance. While both designs prioritise quiet operation, the MSI model explicitly highlights its low-noise feature, appealing to users who value a silent working environment.

Build Quality and Components

The MSI MAG A1000GLS incorporates durable components, including an LLC half-bridge with a DC-to-DC converter and active PFC design, ensuring reliable output with multiple protections such as OCP, OTP, and more. The Gigabyte UD850GM PG5 ICE, on the other hand, boasts 100% Japanese capacitors, known for their high quality and longevity. Both units are built with reliability in mind, but the emphasis on Japanese capacitors in the Gigabyte model may provide an additional assurance of durability to some users.

Performance Under Load

When it comes to performance, the MSI MAG A1000GLS can deliver up to 600W of power specifically for PCIe 5.1 GPUs, making it an excellent choice for high-demand setups. The Gigabyte UD850GM PG5 ICE, while rated at 850W, focuses on a powerful single +12V rail, which can provide stable power distribution across various components. This difference in power delivery approaches may appeal to varied user needs—those prioritising GPU power may lean towards the MSI, while others requiring a balanced distribution might prefer the Gigabyte.

User Experience and Installation

In terms of user experience, both power supplies aim to simplify installation and usability. The fully modular design of the Gigabyte UD850GM PG5 ICE allows for a clean build, as users can easily manage and hide unused cables. The MSI MAG A1000GLS, while not fully modular, offers a compact design that fits comfortably in most PC cases. This can ease installation challenges, especially in tighter spaces. Users may find the modularity of the Gigabyte model enhances flexibility during setup, while the MSI's compactness stands out in terms of space-saving.

Which should you buy?

In conclusion, the choice between the MSI MAG A1000GLS PCIE5 Power Supply Unit and the Gigabyte UD850GM PG5 ICE largely depends on individual needs. The MSI unit, with its strong focus on GPU support and low-noise operation, is ideal for high-performance builds prioritising graphics power. Conversely, the Gigabyte model offers a slightly lower price point, fully modular design, and high-quality Japanese capacitors, making it a strong contender for users looking for reliability and flexibility. Ultimately, both units are excellent choices within the 80 PLUS Gold category; your decision should hinge on whether you value modularity and cost or specialised GPU support and quiet operation.
