The be quiet! Power Zone 2 850W (model Z2-850W, part number BP007EU, EAN 4260052191378) is an 850-watt, fully modular ATX power supply built to the latest ATX 12V 3.1 and EPS 12V 2.92 standards. Carrying both 80 PLUS and Cybenetics Platinum certifications (up to 94.1% efficiency), it ships with a 90°-angled native 12V-2x6 connector for clean cable routing to current high-end NVIDIA andAMD graphics cards. A single high-amperage +12 V rail, LLC topology and a semi-passive Pure Wings 3 140 mm fan make it one of be quiet!’s quietest, most efficient mainstream units — engineered in Germany and backed by a 10-year warranty.
Connector note: The Power Zone 2 uses the latest ATX 3.1 native PCIe Gen5.1 12V-2x6 connector — the updated, safer revision of the 16-pin standard — and its 90° angled design eases cable routing in tight cases. It is fully compatible with current 16-pin (12VHPWR / 12V-2x6) graphics cards; for older GPUs, use the supplied 6+2-pin PCIe cables.
Who It's For
The Power Zone 2 850W suits high-end gaming and creator PCs built around a modern single GPU, where silent operation and Platinum efficiency matter. With native 12V-2x6 delivery, a Zero-RPM fan and a 10-year warranty, it is a premium yet sensibly priced foundation for builders who want a quiet, future-ready ATX 3.1 supply.
Key Features
Platinum-class efficiency
80 PLUS Platinum and Cybenetics Platinum certifications deliver up to 94.1% efficiency — lower power consumption, less heat and quieter, cooler operation for high-end systems.
ATX 3.1 with 90° angled 12V-2x6
A native PCIe Gen5.1 12V-2x6 connector (up to 600 W) handles massive power excursions, and its 90° angled design makes for tidy cable routing. Full PCIe 5.1 and 6+2-pin compatibility with both cables included.
Semi-passive Zero-RPM cooling
A specially tuned Pure Wings 3 140 mm fan stays completely off under low load, with a 2–5 minute post-ventilation phase to avoid frequent start/stop cycles — exceptionally silent across all load scenarios.
Single high-amperage +12V rail
A powerful single +12 V rail (70.8 A) delivers stable, high-load power ideal for demanding CPUs and graphics cards, with advanced voltage regulation via LLC technology.
Fully modular sleeved & flat cabling
Every cable is detachable so you connect only what your build needs, reducing clutter and improving airflow — including 12V-2x6, three PCIe 6+2 and seven SATA connectors.
German engineering + 10-year warranty
Conceived, designed and quality-controlled in Germany, the Power Zone 2 is backed by a 10-year manufacturer warranty for long-term peace of mind.

Frequently Asked Questions
Does the Power Zone 2 850W support the latest RTX graphics cards?
Yes. It is ATX 3.1 / PCIe 5.1 ready and includes a native 90°-angled 12V-2x6 cable rated up to 600 W, so current high-end GeForce RTX and Radeon cards connect directly.
Is this ATX 3.0 or ATX 3.1?
It is the newer ATX 3.1 standard with the updated 12V-2x6 connector (the safer revision of the 16-pin 12VHPWR) and full PCIe Gen5.1 power-excursion support.
Is the fan always running?
No. The Pure Wings 3 140 mm fan uses semi-passive Zero-RPM cooling and stays off under low load, with a short 2–5 minute post-ventilation phase for silent, efficient operation.
Is it fully modular?
Yes, every cable is detachable — sleeved and flat cables — so you install only what your build needs for cleaner routing and better airflow.
What warranty does it carry?

Expert Insight
Power Zone 2 is be quiet!’s value-Platinum line, and it punches above its price: dual Platinum certification (up to 94.1%), a native 90°-angled 12V-2x6 connector and the brand’s first 140 mm semi-passive PSU fan. That combination means it runs cool and is virtually inaudible at typical gaming loads, while the single 70.8 A +12 V rail comfortably feeds a high-end single-GPU system. The angled GPU connector is a Genuinely useful touch for cable routing in compact or glass-panel cases. If you need 1000 W+ for multi-GPU or extreme overclocking, the larger Power Zone 2 models or the Dark/Straight Power ranges step up; for most modern high-efficiency gaming builds, 850 W of Platinum-grade, silent power here is an excellent match.
Buyer's Guide
Best for
Silent, high-efficiency single-GPU gaming & creator builds wanting Platinum efficiency and native 12V-2x6.
Consider
850 W targets a single high-end GPU; for dual-GPU or extreme overclocking choose the 1000 W or 1200 W model.
Also look at
Power Zone 2 1000 W / 1200 W for more headroom, or Straight Power 12 for an even quieter premium tier.
