The be quiet! Straight Power 12 is a 1200W power supply unit designed for high-performance computing systems. It is built to the ATX 3.1 standard, which enables it to handle significant power excursions from modern graphics cards and processors. With an 80 PLUS Platinum certification, this unit operates with high energy efficiency, minimizing waste heat and reducing electricity consumption. The fully modular design allows for the use of only necessary cables, which can simplify the build process and contribute to better airflow within the chassis.
Cooling is managed by a single 135mm fan that provides active airflow to internal components. The unit's construction measures 180mm in depth, a factor to consider for compatibility with certain mid-tower cases. A comprehensive suite of protection circuits is integrated, including overvoltage, overpower, and short circuit protection, to safeguard connected hardware. The power supply also features active Power Factor Correction (PFC) for stable and efficient power delivery across various loads.
