be quiet! Pure Power 13 M 850W (BP027)

be quiet! Pure Power 13 M 850W (BP027) is a modular ATX power supply for modern gaming and workstation PCs, with emphasis on compatibility with new graphics cards and stable voltages under peak loads. The model complies with ATX 3.1 standard and supports PCIe 5.1, featuring a native 12V-2x6 connector (up to 600 W per cable) for current-generation GPUs, as well as 4 PCIe 6+2 pin connectors for previous-generation graphics cards. Rated power output is 850 W, employing a single robust +12 V rail that simplifies load selection for processors and graphics cards. Efficiency is confirmed by 80 PLUS Gold certification with declared efficiency up to 94.4%, reducing heat output and power consumption. The be quiet! Pure Power 13 M 850W (BP027) uses LLC topology with DC-DC conversion for stable voltage regulation, while cooling is provided by a 120 mm fan with semi-passive mode: at low loads, fan speed can stop to minimize noise. Cables are fully modular, facilitating neat routing and improved chassis airflow; peripheral connectors include 6 SATA and 2 Molex. The housing measures approximately 160 mm in length, making it compatible with most ATX cases. Protections include OCP/OVP/UVP/SCP/OTP/OPP, so the be quiet! Pure Power 13 M 850W (BP027) operates correctly during overload, overheating, or short-circuit conditions.
