Price Comparison

The Rosewill VMG 850W 80+ Gold is significantly cheaper than the be quiet! Pure Power 13 M 1000W Power Supply. Priced at $74.97, the Rosewill is about 46% less expensive than the be quiet! option, which retails for $139.90. This makes the Rosewill a more budget-friendly choice for those looking to save on their power supply without sacrificing quality. When considering the price, the Rosewill not only offers a lower upfront cost but also still carries the same 80 PLUS Gold certification, ensuring efficiency in power consumption.

Power Output

The be quiet! Pure Power 13 M offers a robust 1000W of continuous power, making it suitable for high-performance systems and overclocked GPUs. In contrast, the Rosewill VMG provides 850W, which is adequate for many gaming setups but may limit users with more demanding configurations. The additional 150W from the be quiet! model could be a decisive factor for gamers or professionals seeking to future-proof their systems. Ultimately, if maximum output is a priority, the be quiet! model stands out.

Efficiency Ratings

Both power supplies boast 80 PLUS Gold certification, which guarantees high operating efficiency. The be quiet! Pure Power 13 M achieves an impressive efficiency rating of up to 94.4%, promising lower power consumption and heat generation. The Rosewill VMG also meets the 80 PLUS Gold standard, ensuring efficient performance, but specific efficiency figures are not provided. The higher efficiency of the be quiet! could translate to lower electricity bills and better thermal performance over time.

Modular Design

Modularity can significantly ease cable management, and both power supplies offer modular cable options. The Rosewill VMG is fully modular, allowing users to only connect the cables they need, which helps maintain a clean build. The be quiet! Pure Power 13 M also features modular cables, which contributes to improved airflow within the case. This design aspect is crucial for users who prioritize aesthetics and system cooling, making both models suitable for tidy and efficient builds.

Cooling Technology

Cooling performance can affect a power supply's longevity and reliability. The be quiet! Pure Power 13 M incorporates a semi-passive zero-RPM cooling mode, where the fan operates only under higher loads. This feature promotes quiet operation, especially in low-demand scenarios. The Rosewill VMG, on the other hand, includes a 120mm FDB silent fan designed for optimized thermal control. While both models emphasize low noise, the semi-passive cooling of the be quiet! might appeal more to users seeking silent operation during light use.

Compatibility and Future-Proofing

When it comes to compatibility, both power supplies are ATX 3.0 and 3.1 ready. The be quiet! Pure Power 13 M includes native integration for PCIe 5.1 GPUs, along with four PCIe 6+2-pin connectors. This ensures broader support for both current and next-generation graphics cards. The Rosewill VMG also supports PCIe 5.1 with a dedicated 12V-2x6 connector. While both are future-proof, the be quiet! offers slightly more versatility with additional connectors, making it a better choice for users who anticipate needing more support for newer hardware.

Build Quality

Build quality is essential for ensuring the longevity and reliability of a power supply. The be quiet! Pure Power 13 M is constructed with high-class technologies and LLC topology, providing excellent voltage regulation and stability. The Rosewill VMG uses 100% Japanese electrolytic capacitors, known for their durability and reliability under high-stress scenarios. Both power supplies demonstrate good build quality, but the advanced technology employed in the be quiet! may give it an edge in performance and reliability.

Which should you buy?

Choosing between the be quiet! Pure Power 13 M and the Rosewill VMG ultimately depends on your specific needs and budget. If you want maximum power output and advanced cooling technology, the be quiet! Pure Power 13 M is an excellent choice, albeit at a higher price point of $139.90. However, if you're looking for a more budget-friendly option that still offers solid performance and modular design, the Rosewill VMG at $74.97 might be the better fit. It comes down to whether you prioritize power capacity and features over cost savings.
