Product information

Description

be quiet! POWER ZONE 2 850W is an ATX 3.1 power supply unit delivering 850 W continuous power with a single strong 12V rail and peak transient support up to double its rated power. Certified 80 PLUS Platinum and Cybenetics Platinum, this PSU combines high efficiency (up to 94.1%) with a semi-passive zero-RPM cooling concept using a specially adapted Pure Wings 3 140 mm fan. Native 12V-2x6 connector support plus three PCIe 6+2-pin connectors and an included 90° angled 12V-2x6 adapter ensure compatibility with current and next-generation graphics cards.

Advantages

High efficiency reduces power consumption and heat output, improving overall system stability and lowering operating costs. The semi-passive zero-RPM cooling keeps the PSU silent at low loads while the large Pure Wings 3 140 mm fan provides efficient and reliable cooling when required. Native ATX 3.1 features and the supplied angled 12V-2x6 connector make the unit future-proof and versatile for modern GPU demands. Robust LLC topology and a single 12V rail deliver stable voltage regulation suitable for high-end CPUs and GPUs.

Suitable for (tasks / use cases)

  • High-performance gaming PCs with modern graphics cards
  • Content creation and media workstations requiring stable power delivery
  • Quiet PC builds where low noise is important
  • Systems planned for future GPU upgrades (PCIe 5.1 compatibility)

Key specifications

  • Total power: 850 W continuous (peak transient handling up to ~1700 W)
  • 80 PLUS certification: 80 PLUS Platinum (Cybenetics Platinum)
  • Efficiency: up to 94.1% (product data lists 92.3% typical)
  • Fan diameter: 140 mm (Pure Wings 3, semi-passive zero-RPM)
  • Connectors: native 12V-2x6 for PCIe 5.1, 3 × PCIe 6+2-pin, 20+4 pin ATX motherboard connector
  • Form factor: ATX 3.1
  • Color: Black

How to use

Install the PSU into a compatible ATX case following the motherboard and case manufacturer instructions. Connect the 20+4 pin ATX cable to the motherboard and attach PCIe power connectors to the graphics card(s) as required, using the included 90° angled 12V-2x6 adapter if needed for cable routing. Ensure all SATA and peripheral connectors are securely attached. The unit operates semi-passively; the fan remains off at low loads and will start automatically under higher thermal or power demand conditions after a short cooldown delay of about 2–5 minutes to prevent frequent switching.

Usage recommendations

Use this PSU in systems with adequate case ventilation and follow manufacturer guidelines for cable routing and connector compatibility. Allow the recommended cooldown period for the semi-passive fan to avoid frequent start/stop cycles. For optimal reliability, verify that total system power draw stays within the continuous 850 W rating and consider headroom for peak transient loads when planning multi-GPU or heavily overclocked builds.
