Efficiency Ratings

The be quiet! Power Zone 2 boasts an impressive 80 PLUS Platinum certification, providing energy efficiency ratings of up to 94%. This means that the power supply is designed to waste less energy, resulting in lower electricity bills and cooler operation. In comparison, the Auotac 850W is 80 PLUS Gold certified, achieving about 92% efficiency. While both power supplies offer high efficiency, the be quiet! model provides a slight edge in energy savings and performance, making it a better option for users who prioritize energy efficiency and long-term cost savings.

Cooling Solutions

Cooling performance is a critical aspect of any power supply, and here the be quiet! Power Zone 2 stands out with its semi-passive zero-RPM cooling feature. This means that under low load, the fan turns off completely, allowing for silent operation. In contrast, the Auotac 850W features a 140mm low-noise RGB fan but does not offer a similar zero-RPM mode. For users who value a quieter system, especially during light tasks, the be quiet! Power Zone 2 may be the preferable choice. However, the Auotac’s RGB lighting may appeal to those looking to enhance the aesthetics of their build.

Modular Design

Both power supplies feature modular designs, but the Auotac 850W is fully modular, allowing users to connect only the cables they need, which helps to reduce cable clutter. This can lead to improved airflow and overall system efficiency. The be quiet! Power Zone 2 also includes a 90° angled 12V-2x6 connector, enhancing compatibility with next-generation graphics cards, but it does not specify its modularity level. For users who prioritize custom cable management and a tidy setup, the Auotac 850W has a clear advantage with its fully modular design.

Compatibility and Future-Proofing

The be quiet! Power Zone 2 is designed to support future technology with its ATX 3.1 compatibility and PCIe 5.1 readiness, making it suitable for next-generation graphics cards. It comes with both native integration of a 12V-2x6 connector and additional PCIe 6+2-pin connectors for current-generation GPUs. The Auotac 850W also supports ATX 3.1 and PCIe 5.1, ensuring it is compatible with high-performance components. However, the be quiet! model's advanced features and higher wattage make it a more future-proof investment for users planning to upgrade their systems over time.

Build Quality and Components

When it comes to build quality, both power supplies use high-quality components. The Auotac 850W utilizes 105°C-rated Japanese capacitors, which are known for their reliability and durability, ensuring stable performance. The be quiet! Power Zone 2, meanwhile, incorporates LLC topology for enhanced voltage regulation and efficiency. While both models are built to last, the advanced technology in the be quiet! may provide superior performance in high-demand scenarios, making it a better choice for intensive tasks like gaming or content creation.

Brand Reputation

Both Auotac and be quiet! have established reputations in the power supply market, but they appeal to different audiences. Auotac is known for offering budget-friendly options without sacrificing essential features, making it a good choice for gamers or PC builders on a budget. On the other hand, be quiet! is recognized for its focus on silent operation and high efficiency, appealing to users who prioritize quiet performance and premium features. Depending on your brand preference and specific needs, either option could be suitable.

Which should you buy?

Ultimately, the choice between the Auotac 850W Fully Modular Power Supply and the be quiet! Power Zone 2 1000W ATX 3.1 PSU comes down to your specific needs and budget. If you are looking for a cost-effective solution with solid performance, the Auotac 850W is a compelling option at $79.99. However, if you prioritize efficiency, silent operation, and future-proofing with premium features, the be quiet! Power Zone 2, albeit at a higher price of $159.90, may be worth the investment.
