be quiet! Power Zone 2 850W ATX 80 PLUS Platinum PSU with Zero-RPM Cooling

The be quiet! Power Zone 2 850W power supply represents a premium solution for professional workstations, high-performance computing systems and enthusiast gaming configurations. 80 PLUS Platinum and Cybenetics Platinum certifications with efficiency up to 94.1% guarantee reduced power consumption, minimal thermal dissipation and superior operational stability—critical aspects in business environments where equipment reliability directly impacts productivity.

The semi-passive zero-RPM cooling system with customized Pure Wings 3 140mm fan operates completely silently at low to moderate loads, activating only when power demands increase. The intelligent post-ventilation algorithm (2-5 minute cooldown) prevents frequent starts/stops and intermittent noise, essential for quiet professional environments—recording studios, open-space offices or workstation configurations in close user proximity.

ATX 3.1 and PCIe 5.1 compatibility with native 12V-2x6 connector (including 90° angled variant) ensures support for latest-generation professional GPUs like NVIDIA RTX Ada Lovelace or AMD Radeon PRO, eliminating adapter requirements and simplifying cable management. The PSU also provides 3 PCIe 6+2-pin connectors for backward compatibility with current graphics cards, making it versatile for staged upgrades.

Architecture with single massive 12V rail delivering 850W efficiently manages power demands of multi-GPU configurations, high-core-count processors (AMD Ryzen 9/Threadripper, Intel Core i9) and systems with advanced overclocking. Capability to handle transient loads up to 200% rated power protects against current spikes generated by modern GPUs under maximum load, preventing unexpected shutdowns in mission-critical applications—rendering, scientific simulations or 8K video processing.

LLC (LLC resonant converter topology) technology delivers superior voltage regulation and exceptional electrical stability, reducing ripple and electrical noise—an important factor for system stability with sensitive components (professional audio, high-end video capture) or precise overclocking. The distinctive mesh front design and cable designations printed directly on the case facilitate rapid identification during servicing and maintenance.

The 10-year manufacturer warranty confirms be quiet! reliability in long-term deployments, reducing TCO (Total Cost of Ownership) in workstation fleets or mission-critical business configurations where component replacement involves significant costs.

Ideal for: CAD/3D rendering workstations with RTX Ada/Radeon PRO, 8K video editing stations with multiple GPUs, development systems with high-TDP CPUs and overclocking, enthusiast gaming configurations with RTX 4090/4080, entry-level tower servers for SMB, silent builds for multimedia studios, deployment in corporate environments with energy efficiency requirements, AI/ML platforms with power-intensive compute accelerators, data analysis systems with dual-GPU professional configurations.
