The be quiet! Straight Power 12 is an 850W power supply unit designed for systems that require stable and efficient power delivery. It features an 80 PLUS Platinum certification, which signifies high efficiency during operation, leading to reduced energy consumption and less heat output. This model complies with the ATX 3.1 standard, ensuring compatibility with modern hardware components that have high transient power demands. The fully modular design allows users to connect only the necessary cables, which can assist with cleaner build aesthetics and improved airflow inside the chassis.
Cooling is handled by a single 135mm fan that is optimized for low-noise performance, operating at a specified level of 22.1 dB. The unit is built to the standard ATX form factor with a depth of 160mm, making it suitable for a wide range of PC cases. For component safety, it incorporates a comprehensive suite of protection circuits, including over-voltage, over-power, and short-circuit protection. The active Power Factor Correction (PFC) contributes to stable power output, and the unit is rated for a Mean Time Between Failures (MTBF) of 100,000 hours.
