be quiet! Pure Power 13 M 850W Power Supply vs CORSAIR SF850

Overview of the Products

In this comparison, we will look at the be quiet! Pure Power 13 M 850W Power Supply and the CORSAIR SF850. The be quiet! model is priced at C$173.21, while the CORSAIR option is significantly more expensive at C$279.99. Both power supplies cater to different needs, with unique features that may appeal to various users.

The be quiet! Pure Power 13 M is designed with high efficiency in mind, achieving an 80 PLUS Gold rating, which guarantees an efficiency of up to 94.4%. On the other hand, the CORSAIR SF850 boasts an 80 PLUS Platinum rating, indicating even higher efficiency and power delivery in a compact form factor.

Efficiency and Certification

Efficiency is a critical factor when selecting a power supply, and both products excel in this area. The be quiet! Pure Power 13 M holds an 80 PLUS Gold certification, ensuring a high operating efficiency of up to 94.4%. This translates to lower power consumption, which can lead to reduced electricity costs over time.

Conversely, the CORSAIR SF850 takes efficiency a step further with its 80 PLUS Platinum rating. While the exact efficiency percentage isn't specified in the data, Platinum-rated power supplies typically exceed 90% efficiency at 20%, 50%, and 100% loads. For users prioritizing energy savings, the CORSAIR model may provide an edge in operational efficiency.

Form Factor and Size

The form factor of a power supply can significantly impact its installation and compatibility with various systems. The be quiet! Pure Power 13 M is an ATX 3.1 PSU, which is well-suited for most standard cases and can accommodate high-performance components.

In contrast, the CORSAIR SF850 is an SFX power supply, specifically designed for compact builds and small form-factor cases. This makes the CORSAIR SF850 ideal for users looking to save space or build a high-performance system in a tighter enclosure. The compact design does not compromise on power, as it still delivers a robust 850W output.

Cooling Solutions

Cooling is essential for maintaining stable performance in power supplies. The be quiet! Pure Power 13 M features a semi-passive zero-RPM cooling mode, which allows the fan to completely turn off under low loads. This results in near-silent operation during less demanding tasks, making it an excellent choice for quiet systems or gaming PCs.

On the other hand, the CORSAIR SF850 is equipped with a 92mm PWM cooling fan. This fan is designed for powerful cooling while ensuring low noise levels thanks to its fluid dynamic bearing. While both power supplies aim for quiet operation, the be quiet! model's zero-RPM mode may offer an advantage in scenarios where silence is paramount.

Connectivity Options

Connectivity is a crucial aspect when choosing a power supply, especially for modern gaming setups. The be quiet! Pure Power 13 M supports the latest ATX 3.1 specifications and includes a native 12V-2x6 connector for next-generation PCIe 5.1 graphics cards. This feature enhances its versatility, accommodating both current and future GPU requirements with its four PCIe 6+2-pin connectors.

Meanwhile, the CORSAIR SF850 also supports the latest standards, being ATX 3.0 compliant and PCIe 5.0 ready. It features fully modular Type-5 Micro-Fit PSU connectors, which not only facilitate tidy cable management but also enhance compatibility in smaller cases. Both options provide robust connectivity, but the be quiet! model shines with its dedicated support for next-gen graphics.

Build Quality and Components

The quality of components used in power supplies can greatly affect their reliability and longevity. The be quiet! Pure Power 13 M boasts high-class technologies, including LLC topology for superior voltage regulation and efficiency. This ensures solid stability and reliable operation, especially important for users pushing their systems to the limits.

In comparison, the CORSAIR SF850 is built with 105°C rated Japanese capacitors, known for their reliability and performance under stress. This reinforces the product's durability and can help maintain consistent power delivery over time. Both power supplies are built with quality components, but the specific focus on temperature-rated components in the CORSAIR model may give it an edge in extreme conditions.

Price Comparison

Price is often a deciding factor when purchasing a power supply. The be quiet! Pure Power 13 M is priced at C$173.21, making it a more budget-friendly option for users seeking high efficiency and solid performance. This pricing makes it particularly appealing to gamers and PC builders who want a reliable power source without breaking the bank.

In contrast, the CORSAIR SF850 comes with a higher price tag of C$279.99. While it offers enhanced features such as an 80 PLUS Platinum rating and compact SFX design, the significant price difference may deter budget-conscious consumers. Users need to weigh the benefits of the additional features against the cost to determine the best value for their needs.

Which should you buy?

Choosing between the be quiet! Pure Power 13 M 850W Power Supply and the CORSAIR SF850 ultimately comes down to individual needs and preferences. If you are looking for a cost-effective, high-efficiency option with excellent cooling features, the be quiet! model is a strong contender at C$173.21. However, if you prefer a compact power supply with Platinum-level efficiency and premium components, the CORSAIR SF850, despite its higher price of C$279.99, might be worth the investment. Each power supply has its strengths, making it essential to assess your specific requirements before making a decision.
