Be Quiet! Power Zone 2 850W - High-Efficiency Modular Power Supply

The Power Zone 2 850W delivers platinum-certified efficiency and silent operation for demanding gaming and content creation systems. With 80 PLUS Platinum and Cybenetics Platinum ratings achieving up to 94.1% efficiency, this fully modular PSU reduces power consumption while maintaining cooler, quieter performance.

Semi-Passive Zero-RPM Cooling Technology

A specialized Pure Wings 3 140mm fan with rifle bearing provides exceptional cooling when needed, while remaining completely silent under low loads. The intelligent semi-passive design includes a 2-5 minute post-ventilation cooldown period to prevent frequent fan cycling and eliminate annoying start-stop noise. This combination of large-diameter fan and smart thermal management ensures whisper-quiet operation across all load scenarios.

ATX 3.1 and PCIe 5.1 Ready

Built for current and next-generation systems, the Power Zone 2 850W features native 12V-2x6 connector support with an included 90° angled adapter for PCIe 5.1 graphics cards. Three PCIe 6+2-pin connectors maintain compatibility with existing GPUs, making this PSU versatile for any high-performance build. The single massive 12V rail handles transient power excursions up to double the rated capacity, ensuring stable operation with power-hungry modern processors and graphics cards.

Advanced Voltage Regulation

LLC topology provides best-in-class voltage regulation and stability, critical for system reliability under demanding workloads. Comprehensive protection includes OTP, OCP, OPP, SCP, OVP, UVP, and SIP safeguards. The distinctive mesh front design houses clearly printed cable designations directly on the PSU case for easy identification and professional aesthetics.

Complete Connectivity

Fully modular cable design includes 1x ATX 20+4-pin motherboard, 1x P4+4 CPU, 1x P8 CPU, 1x P4 CPU, 1x 12VHPWR, 3x PCIe 6+2-pin, 7x SATA, and 1x PATA connectors. Compact 160 x 150 x 86mm dimensions fit standard ATX cases. Backed by a 10-year manufacturer's warranty and rated for over 100,000 hours MTBF, the Power Zone 2 850W is engineered for long-term reliability in high-end systems.

Platinum Certified

Highly efficient operation
Power Zone 2 850W is certified with 80 PLUS Platinum and Cybenetics Platinum, resulting in an energy efficiency rating of up to 94.1%. This results in lower power consumption, overall cooler and quieter operation, and many other benefits for your high-end system.



Semi-Passive Zero-RPM Cooling

Enjoy the silence
A large Pure Wings 3 140mm fan is keeping Power Zone 2 850W cool. While under low load, the fan turns off completely until its services are needed again for more demanding operations. This post-ventilation requires a short cooldown period of 2-5 minutes to avoid frequent and annoying starts and stops of the fan. Combined with the large fan for active cooling, this power supply is exceptionally silent in all load scenarios.




Pure Wings 3 Fan

Specially designed for Power Zone 2
No Power Supply is like the other. Hence, we have altered aspects of our renowned Pure Wings 3 140mm fan to make it the perfect match for Power Zone 2 850W. The fan offers outstanding reliability and makes for a long-lasting companion. Due to its large diameter, the fan cools the interior of the PSU efficiently and quietly.



Future-Proof Your System

With 90° angled 12V-2x6 connector in scope of delivery
Power Zone 2 850W is an ATX 3.1 PSU and comes with both native integration of the 12V-2x6 connector for next-generation PCIe 5.1 graphics cards, and 3 PCIe 6+2-pin connectors for support of current-gen GPUs. A 90° angled 12V-2x6 connector in the scope of delivery leaves no doubt that this PSU is here to stay. All of this makes Power Zone 2 850W extremely versatile and the perfect choice for powerful systems of today and the ones to come.



The New Standard Of Power

For massive transient loads
Power Zone 2 offers 850W of continuous power with one massive 12V rail. Even if the graphics card demands excessive power for a short time: Power Zone 2 850W handles power excursions up to double its rated power with ease. This ensures reliable operation with the next generation of processors and graphics cards.




High-Class Technologies

All packed in a stunning design
With its LLC topology, the Power Zone 2 850W offers best-in-class voltage regulation and efficiency. This makes it perfect for building very quiet systems or upgrading gaming and media creation PCs. The inner values are what everyone cares about most in a power supply but looks cannot be completely ignored. That is why the Power Zone 2 850W has a distinctive look with a newly designed mesh front. In addition, all cable designations are printed directly on the PSU's case for a long-lasting impression and an unparalleled look and feel.
