be quiet! PURE POWER 12 850W 80 Plus Gold PSU ATX 3.1 PCIe 5.1 - BP004EU

be quiet! PURE POWER 12 850W is an 850W modular ATX power supply from the higher mid-range to high-end class, aimed at modern gaming and workstation configurations. It relies on 80+ Gold certification and efficiency up to 92.9%, so you lose less energy as heat and put less strain on the electrical installation. Support for ATX 3.1 and PCIe 5.1 means you are fully prepared for the new generation of GPUs, including with a 12VHPWR/12V-2x6 connector. In typical be quiet! style, the focus is on stability, quiet operation, and reliability for a long-term build.

What you get

With a power of 850W and a massive 12V rail, you have enough resources for overclocked high-end GPUs and more serious CPUs without worrying about sudden voltage drops. The built-in LLC technology for voltage management provides a more stable output and less risk of instability during peak consumption, which is important under load in gaming or rendering. The modular design allows you to install only the necessary cables, improving airflow and making cable management easier. Thanks to the PCI-E Gen5 12VHPWR / 12V-2x6 600W connector, you can power modern graphics cards directly without adapters, and the three additional PCI-Express 6+2 pin connectors leave room for alternative GPUs or future upgrades. Active PFC helps for better efficiency and cleaner power from the grid, while a 120mm fan keeps everything cool and quiet.

• Power 850W – sufficient for high-end gaming and creative configurations with a powerful graphics card and many peripherals.
• 80+ Gold efficiency (up to 92.9%) – lower consumption, less heat, and quieter operation under typical load.
• ATX 3.1 with full support for PCIe 5.1 GPUs – readiness for the latest GPUs, including models with higher peak loads.
• One PCIe 5.1 12V-2x6 600W and 3 PCIe 6+2 connectors – direct power for modern graphics cards and freedom for future upgrades or multi-GPU scenarios.
• Modular design – cleaner interior of the case, better airflow, and easier assembly and maintenance.
• LLC technology and one powerful 12V rail – better voltage stability and reliability during sudden peaks in consumption.
• 120mm fan and black color without RGB – aimed at quiet, clean builds without unnecessary lights.

Who it is suitable for

This power supply is a good foundation for a serious gaming PC with a modern PCIe 5.1 GPU, 1440p or 4K oriented build, as well as for a workstation for video processing or 3D rendering. It is suitable if you want an ATX 3.1 PSU that you won’t have to replace with the next generation of graphics cards. It is not the most sensible choice if you are aiming for a completely budget build with low consumption or a small ITX system, where you might look for lower power or a different form factor.

The combination of 850W power, 80+ Gold efficiency, and full ATX 3.1 / PCIe 5.1 support makes PURE POWER 12 850W a long-term solution that comfortably handles today’s high-end components and leaves room for upgrades tomorrow.
