The be quiet! Pure Power 12 850W (BP004) is an 850 W ATX power supply designed for quiet gaming and workstation systems with modern processors and graphics cards, where not only rated power but also compliance with new peak load requirements matter. The unit is compatible with ATX 3.1 and PCIe 5.1, carries 80 PLUS Gold certification with efficiency up to 92.7%, and handles short-term power spikes up to twice the rated output, essential for new-generation GPUs. The be quiet! Pure Power 12 850W (BP004) features a single robust +12 V rail, LLC topology, and a 120 mm proprietary be quiet! fan tuned for low noise operation. This makes the power supply ideal for systems where voltage stability and quiet performance under load are priorities. The be quiet! Pure Power 12 850W (BP004) uses a non-modular design with braided black sleeves on main cables and flat black ribbon cables for the remainder, simplifying cable management inside the chassis. Connection options include a native 12V-2x6 cable rated for 600 W and three PCIe 6+2-pin connectors for compatibility with graphics cards of different generations. The be quiet! Pure Power 12 850W (BP004) is worth considering for a high-performance single-GPU system when you need Gold-level efficiency, ATX 3.1 support, modern GPU power delivery, and quiet cooling without stepping up to more expensive fully modular models.
