Price Comparison
The be quiet! Pure Power 13 M 850W Power Supply is priced at C$173.21, while the PCCOOLER PSU Fully Modular Power Supply comes in at a lower price of C$125.99. This significant price difference of C$47.22 may make the PCCOOLER an attractive option for budget-conscious shoppers. However, the higher cost of the be quiet! model reflects its advanced features and capabilities, particularly in efficiency and noise management.
Efficiency Ratings
When it comes to efficiency, both power supplies offer excellent performance, with both models being 80 PLUS Gold certified. The be quiet! model boasts an outstanding efficiency rating of up to 94.4%, which translates to lower power consumption and reduced energy costs. In comparison, the PCCOOLER is slightly less efficient, delivering up to 92% efficiency under typical loads. While both are highly efficient, the be quiet! offers a marginally better performance, making it ideal for those prioritizing energy savings.
Design and Modularity
The PCCOOLER PSU features a fully modular design, which allows users to connect only the cables they need, promoting cleaner cable management and improved airflow. The be quiet! Pure Power 13 M is not fully modular but still offers some flexibility with its design. It supports the latest ATX 3.1 specifications and comes with native 12V-2x6 connectors for next-gen GPUs. If having a fully modular setup is essential for you, the PCCOOLER takes the lead in this category.
Cooling Solutions
Both power supplies incorporate smart cooling solutions. The be quiet! model features semi-passive zero-RPM cooling, meaning its fan turns off completely under low load, ensuring silent operation. In contrast, the PCCOOLER has a temperature-controlled 120mm hydraulic bearing fan that operates quietly during low loads but ramps up under heavy demand. The be quiet! is designed specifically for quiet systems, making it a better choice for users who value silence above all.
Capacitors and Reliability
The PCCOOLER PSU is built with high-quality 105°C Japanese capacitors, ensuring long-term stability and reliability even in demanding environments. The be quiet! model does not specify the types of capacitors used but emphasizes its rock-solid stability and best-in-class voltage regulation. While both power supplies offer reliable performance, the explicit mention of premium components in the PCCOOLER adds an extra layer of assurance for users concerned about durability.
Compatibility and Future-Proofing
Both power supplies are compliant with the latest ATX 3.1 specifications and are equipped to handle next-generation components. The be quiet! Pure Power 13 M features both a native 12V-2x6 PCIe 5.1 connector and multiple PCIe 6+2-pin connectors for current-gen GPUs, making it extremely versatile. The PCCOOLER also includes a native 12V-2x6 PCIe 5.1 connector, ensuring it can support the latest high-performance GPUs. Both models are well-suited for future upgrades, but the additional connectors on the be quiet! provide a slight edge in versatility.
Noise Levels
In terms of noise, the be quiet! Pure Power 13 M is designed with silent operation in mind, particularly due to its semi-passive cooling feature that keeps the fan off during low loads. The PCCOOLER also prioritizes quiet operation with its smart fan control system, but it may not be as silent as the be quiet! under low load conditions. For users particularly sensitive to noise, the be quiet! model stands out as the quieter option.
Which should you buy?
Ultimately, the choice between the be quiet! Pure Power 13 M 850W Power Supply and the PCCOOLER PSU Fully Modular Power Supply hinges on your specific needs and preferences. If you prioritise superior efficiency, silent operation, and the flexibility of supporting both current and next-gen components, the be quiet! model is worth the higher price of C$173.21. Conversely, if you are looking for a budget-friendly option without sacrificing essential features like modularity and solid performance, the PCCOOLER at C$125.99 is an excellent choice. Consider your priorities, and select the power supply that best meets your criteria.
