be quiet! Pure Power 13 M 850W Power Supply vs Cooler Master V850 SFX Gold White Edition Full Modular

Price Comparison

The be quiet! Pure Power 13 M 850W Power Supply is priced at C$173.21, making it a more economical choice compared to the Cooler Master V850 SFX Gold White Edition, which retails for C$220.99. This C$47.78 difference highlights the Pure Power 13 M as a budget-friendly option for users looking for an efficient power supply without breaking the bank. While both products are certified 80 PLUS Gold, the lower price of the be quiet! model may appeal to those seeking value in their build.

Efficiency and Certification

Both power supplies boast an 80 PLUS Gold certification, but their efficiency ratings vary under different operating conditions. The be quiet! Pure Power 13 M achieves an impressive efficiency rating of up to 94.4%, which translates to substantial energy savings and reduced heat generation. In contrast, the Cooler Master V850 SFX Gold White Edition guarantees a typical efficiency of 90% under normal conditions. Users prioritising maximum energy efficiency may find the be quiet! model a better investment in the long run.

Form Factor

When it comes to form factor, the Cooler Master V850 SFX Gold White Edition excels with its SFX design, making it compatible with all SFX cases and ideal for mini-ITX system builds. This flexibility is particularly appealing for users with space constraints. On the other hand, the be quiet! Pure Power 13 M adheres to the ATX form factor, which is standard for many builds but may not suit compact environments. Thus, if you are looking to build a small form factor system, the Cooler Master will be the preferable choice.

Cable Management

The Cooler Master V850 SFX Gold White Edition features full-modular cabling, allowing users to connect only the cables they need, which reduces clutter and promotes better airflow within the case. This design significantly improves thermal performance and overall system efficiency. Meanwhile, the be quiet! Pure Power 13 M does not highlight modular cabling in its features, suggesting a non-modular or semi-modular approach. For users prioritising optimal cable management, the Cooler Master model stands out as the superior option.

Cooling Solutions

The be quiet! Pure Power 13 M incorporates semi-passive zero-RPM cooling, allowing the fan to turn off completely under low load conditions, thus ensuring silent operation during non-demanding tasks. This feature is particularly beneficial for users focused on building quiet systems. The Cooler Master V850 SFX Gold White Edition, while not explicitly mentioned to have a similar feature, does utilise an FDB (Fluid Dynamic Bearing) fan, which generally enhances longevity and quiet operation. If silence is crucial for your build, the be quiet! model may be the better choice.

Power Capacity and Stability

The be quiet! Pure Power 13 M delivers a robust 850W of continuous power via a single massive 12V rail, capable of handling power excursions up to double its rated power. This ensures reliable operation even with demanding components. In comparison, the Cooler Master V850 SFX Gold White Edition also offers 850W, but its focus on SFX form factor may limit its application for users with high power demands. Both units provide ample power, yet the be quiet! unit's ability to manage transient loads could be seen as an advantage for high-performance builds.

Compatibility with Graphics Cards

The be quiet! Pure Power 13 M is designed with future-proofing in mind, featuring native support for the 12V-2x6 connector, essential for next-generation PCIe 5.1 graphics cards, along with four PCIe 6+2-pin connectors for current GPU models. This makes it highly versatile for users looking to upgrade their graphics setup. The Cooler Master V850 SFX Gold White Edition does not mention specific support for next-generation connectors, which may limit its appeal to those planning to use the latest graphics technologies. Therefore, if you're anticipating an upgrade path with newer GPUs, the be quiet! model is likely the better option.

Which should you buy?

Ultimately, the choice between the be quiet! Pure Power 13 M 850W Power Supply and the Cooler Master V850 SFX Gold White Edition depends on your specific needs. If you're looking for a more budget-friendly option with superior efficiency and silent operation, the be quiet! model is the clear winner. However, if you require a compact power supply for a mini-ITX build and value modular cabling for better cable management, the Cooler Master variant may be worth the higher price. Consider your system requirements and future upgrade plans to make the best decision for your build.
