Overview
The be quiet! Pure Power 12 650W PSU is priced at $64.90, while the Vetroo 850W Power Supply comes in at $79.99. This makes the be quiet! option about 17% cheaper than the Vetroo model. Both power supplies are certified 80 Plus Gold, ensuring energy efficiency, but they cater to slightly different needs in terms of power output and features.
Power Output
The Vetroo 850W Power Supply offers a higher power output compared to the be quiet! Pure Power 12 650W, providing 850W versus 650W. This 200W difference allows the Vetroo to support more demanding systems, particularly for high-end gaming rigs that may require additional power for multiple graphics cards or overclocked components. If you’re planning to build a system that may require significant power, the Vetroo could be more suitable.
Design and Build Quality
Both power supplies feature a modular design, but the Vetroo emphasizes a fully modular approach which allows users to connect only the cables they need. This can lead to improved cable management and airflow within the case. The be quiet! model also supports modular cables, but its emphasis is on reducing noise with a temperature-controlled fan. The Vetroo's 120mm FDB fan is designed for quiet operation as well, but it is important to note that both models prioritize silent performance.
Efficiency and Certification
Both power supplies are certified 80 Plus Gold, which means they are designed to be highly efficient under typical loads. The be quiet! Pure Power 12 boasts an efficiency rating of up to 92.7%, indicating excellent energy savings and lower heat output during operation. The Vetroo also meets the same standard but does not specify its exact efficiency rating. This makes the be quiet! a potentially more efficient option, especially for users who prioritize energy consumption.
Compatibility
In terms of compatibility, both options are ATX 3.1 compliant and support PCIe 5.1 graphics cards. The be quiet! Pure Power 12 includes a native 12V-2x6 connector and two PCIe 6+2-pin connectors for versatility with both current and next-gen GPUs. The Vetroo is also fully ATX 3.1 compliant and supports the latest PCIe standards, ensuring it is ready for the most modern builds. This makes both models excellent choices for gamers and PC builders aiming for future-proofing.
Cooling Performance
Cooling performance is a critical factor in maintaining system stability and longevity. The be quiet! Pure Power 12 features a temperature-controlled 120mm fan that is designed for near-silent operation, making it ideal for quiet systems. The Vetroo also includes a 120mm fan, designed for quiet operation, but specific details about its cooling efficiency are not provided. Users looking for a power supply that emphasizes silent performance might lean towards the be quiet! option.
