This article covers 静かに!Pure Power 12 850W 電源.

Overview

The be quiet! Pure Power 12 850W is an ATX 3.1 power supply that achieves up to 92.7% efficiency, earning 80 Plus Gold certification. It features a native 12V-2x6 connector for PCIe 5.1 graphics cards, a temperature-controlled 120mm fan, and LLC resonant topology for stable output. With 850W of continuous power on a single +12V rail, this unit is well-suited for mid-to-high-end gaming PCs and workstations. It sits in the mid-range segment, offering a compelling balance between price, noise level, and modern connectivity. While not fully modular, its fixed cables are of good quality and sleeved for easier routing.

Compatibility Guide

Standard ATX form factor fits most mid-tower and full-tower cases. The PSU includes one EPS12V CPU cable, three PCIe 6+2 pin cables, and one 12V-2x6 (12+4 pin) cable, covering current and next-gen GPUs. Additionally, it provides eight SATA and four Molex connectors for storage and peripherals. Because the cables are non-modular, ensure your case has enough space behind the motherboard tray for cable management. The 24-pin ATX cable is thick, so plan routing carefully.

Product Info

The be quiet! Pure Power 12 850W launched in 2024 as a mid-range 80 Plus Gold PSU with ATX 3.1 compliance. Its market position is "quiet-focused Gold PSU with future-ready connectors," sitting below the premium Dark Power 13 series but offering essential modern features at a lower price. Key specs: 850W rated, 80 Plus Gold, ATX 3.1, 12V-2x6 connector, 120mm silent fan, LLC topology. The warranty is 5 years. Pricing is competitive with other 850W Gold units.

Best Use Cases

  • Silent PC builders: The quiet 120mm fan and efficient circuitry keep noise low even under load. Pair with a silenced case and low-noise cooler for near-silent operation. - Gamers with current-generation GPUs: The native 12V-2x6 connector ensures seamless power delivery to RTX 40-series and upcoming cards without adapters. The strong transient response handles power spikes reliably. - Budget-conscious users who want quality: 5-year warranty and stable performance at a competitive price make this a smart choice for value-oriented builds that still require modern standards. ## Alternatives
    Direct competitors include the Corsair RM850e and Seasonic Focus GX-850. The Corsair RM850e features fully modular cables, making cable management easier, but its fan noise is slightly higher at full load. The Seasonic Focus GX-850 also offers modularity and excellent efficiency, but some variants lack the native 12V-2x6 connector, requiring an adapter for RTX 40-series cards. The Pure Power 12's fixed cables are a drawback for clean builds, but its noise performance and native connector give it an edge for silent-focused systems.

Things to Consider

The non-modular cable design can clutter the case interior, especially in smaller builds. The unit comes with only one 12V-2x6 cable rated up to 450W, which may be insufficient for ultra-high-end GPUs like the RTX 4090 during transient spikes. Additionally, the 120mm fan is quiet but not silent — under heavy load it becomes audible. For those who prioritize modularity or plan to use custom cables, a modular alternative like the RM850e might be preferable. However, for a standard gaming PC targeting up to RTX 4080-class GPUs, the Pure Power 12 is a strong, reliable choice.
