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

Pricing Comparison

When evaluating the be quiet! Pure Power 13 M 850W Power Supply and the MSI MAG A850GL PCIE5 White, pricing is a significant factor. The be quiet! model is priced at C$173.21, while the MSI unit is higher at C$199.99. This represents a difference of C$26.78, making the be quiet! option the more affordable choice. For users on a budget, this cost differential may influence the decision, particularly when considering similar features and capabilities.

Efficiency Ratings

Efficiency is a crucial aspect of power supplies, and here the be quiet! Pure Power 13 M shines with its 80 PLUS Gold certification, boasting an efficiency rating of up to 94.4%. This high efficiency not only results in lower power consumption but also translates to reduced energy costs and a quieter operation, especially desirable for gaming systems. In contrast, the MSI MAG A850GL lacks a specific efficiency rating, which could be a drawback for users who prioritise energy efficiency in their components.

Design and Build Quality

The design of a power supply can significantly affect its installation and overall aesthetics. The MSI MAG A850GL features a full modular design with flat cables, which can simplify cable management and contribute to a cleaner build. Meanwhile, the be quiet! Pure Power 13 M, while not mentioned as modular, is designed with a focus on silence and efficiency, including a semi-passive mode where the fan operates only under higher loads. This aspect can appeal to users looking for quieter systems, though it lacks the aesthetic flexibility offered by the MSI's modular design.

Cooling Capabilities

Cooling performance is vital for maintaining optimal operating conditions in a power supply. The be quiet! Pure Power 13 M incorporates a semi-passive zero-RPM cooling feature, allowing the fan to remain off during low load scenarios, which enhances its silence during idle periods. The MSI MAG A850GL, on the other hand, is equipped with a 120mm Fluid Dynamic Bearing fan, which is known for quieter operation and reliability. While both units aim for quieter performance, the be quiet! model stands out with its innovative approach to cooling.

Power Output and Stability

Power output is essential for ensuring that your system runs smoothly, especially under heavy loads. The be quiet! Pure Power 13 M delivers a continuous output of 850W through a single massive 12V rail, capable of managing transient loads effectively. This ensures reliable operation even when high-demand components, like next-generation GPUs, draw power. The MSI MAG A850GL also supports ATX 3.1 standards and features native PCIe 5.1 connectivity, but specific power output figures are not mentioned. As such, the be quiet! model provides more concrete assurance of its capabilities.

Future-Proofing

Future-proofing is a critical consideration for gamers and PC builders looking to invest in long-lasting components. The be quiet! Pure Power 13 M is designed to fulfil all ATX 3.1 specifications and includes a 12V-2x6 connector for next-generation PCIe 5.1 graphics cards, making it a versatile choice for both current and future builds. The MSI MAG A850GL also supports ATX 3.1 and offers a native PCIe 5.1 dual-color 16-pin cable, which is essential for modern graphics cards. Both models demonstrate future-ready features, but the be quiet! unit provides additional details regarding its capacity for handling transient loads.

Protection Features

Protection features in a power supply are vital for safeguarding both the unit and the connected components. The MSI MAG A850GL offers an impressive range of industrial-level protections, including Over Voltage Protection (OVP), Over Current Protection (OCP), Over Power Protection (OPP), Over Temperature Protection (OTP), Short Circuit Protection (SCP), and Under Voltage Protection (UVP). In comparison, the be quiet! Pure Power 13 M focuses on stability with its LLC topology for voltage regulation but lacks specific mentions of additional protective features. Thus, the MSI model provides a more comprehensive safety net for users concerned about potential electrical issues.

Which should you buy?

In determining which power supply to purchase, the choice between the be quiet! Pure Power 13 M 850W and the MSI MAG A850GL PCIE5 White comes down to your specific needs. The be quiet! model is the more affordable option, offering superior efficiency and a focus on silent operation, making it ideal for quiet systems and gaming PCs. Conversely, the MSI unit provides robust protection features and a modular design that may appeal to users prioritising aesthetics and safety. Ultimately, if budget and efficiency are your primary concerns, the be quiet! Pure Power 13 M is the standout choice, while the MSI may suit those looking for a more feature-rich power supply.
