MSI MAG A850GL PCIE5 vs be quiet! Pure Power 13 M 850W Power Supply

Price Comparison

The MSI MAG A850GL PCIE5 is priced at C$178.97, while the be quiet! Pure Power 13 M 850W Power Supply is slightly more affordable at C$173.21. The price difference of C$5.76 may seem minimal, but it could influence budget-conscious buyers. Both power supplies offer high efficiency and modern features, making them strong contenders in the market, but if you're looking to save a bit, the be quiet! option stands out as the more economical choice.

Efficiency Ratings

Both power supplies boast an 80 Plus Gold certification, ensuring high operating efficiency. The MSI MAG A850GL PCIE5 is designed for high efficiency but does not specify its maximum efficiency rating. In contrast, the be quiet! Pure Power 13 M claims an outstanding efficiency rating of up to 94.4%. This higher efficiency not only contributes to lower power consumption and reduced costs but also ensures quieter operation, making the be quiet! model particularly appealing for users who prioritise noise reduction in their systems.

Compatibility

The MSI MAG A850GL PCIE5 is ATX 3.0 compatible and features a native PCIe 5.0 connector, positioning it well for current and next-gen graphics cards like the NVIDIA GeForce RTX 40 Series. On the other hand, the be quiet! Pure Power 13 M is ATX 3.1 compliant, offering even greater versatility with its integration of the 12V-2x6 connector for next-generation PCIe 5.1 graphics cards, along with four PCIe 6+2-pin connectors for current GPUs. Thus, while both power supplies support modern hardware, the be quiet! model is better equipped for future upgrades.

Design and Build Quality

The MSI MAG A850GL PCIE5 features a full modular design with flat cables, which aids in cable management and airflow within a PC case. Meanwhile, the be quiet! Pure Power 13 M also focuses on quiet operation with a semi-passive zero-RPM cooling feature, allowing the fan to turn off completely under low load. This design choice, combined with its airflow-optimised fan blades, enhances its overall silent operation. Although both units are well-designed, the be quiet! model may offer a quieter experience under various load conditions.

Power Performance

The MSI MAG A850GL PCIE5 is built to support high-performance components with its robust design. However, specific power performance metrics are not detailed in its product features. In contrast, the be quiet! Pure Power 13 M provides 850W of continuous power, supported by a single massive 12V rail. This capability allows it to handle power excursions up to double its rated power, ensuring reliable operation even under heavy loads from modern CPUs and GPUs. For users looking for a unit that can manage extreme power demands, the be quiet! model clearly comes out on top.

Cooling Solutions

Cooling is critical for maintaining system performance and longevity. The MSI MAG A850GL PCIE5 does not provide specific details about its cooling solutions but implies efficiency through its active PFC design and industrial-level protections. Conversely, the be quiet! Pure Power 13 M features a semi-passive zero-RPM cooling system that prioritises silence by turning off the fan under low loads. This not only enhances user experience but also contributes to a cooler operating environment, giving the be quiet! a significant advantage in this category.

Features and Protection

Both power supplies include protections that enhance safety and reliability. The MSI MAG A850GL PCIE5 includes protections such as OVP (Over Voltage Protection), OCP (Over Current Protection), OPP (Over Power Protection), OTP (Over Temperature Protection), SCP (Short Circuit Protection), and UVP (Under Voltage Protection). The be quiet! Pure Power 13 M, while not detailing the same extensive protections, emphasises its LLC topology for best-in-class voltage regulation and efficiency. Users seeking comprehensive protection features may find the MSI offering more reassuring.

Which should you buy?

Ultimately, the choice between the MSI MAG A850GL PCIE5 and the be quiet! Pure Power 13 M 850W Power Supply hinges on your specific needs. If budget is a priority, the be quiet! model's lower price and superior efficiency make it an attractive option. However, for those prioritising extensive protection features and a solid connection for current GPUs, the MSI model offers compelling advantages. Consider your current and future hardware requirements, budget constraints, and personal preferences in noise levels when making your decision.
