Product Description
Be Quiet! Power Zone 2 850W Unrivaled Silence Meets Elite Power Delivery
Platinum Efficiency for Demanding Systems
Be Quiet! Power Zone 2 850W stands at the intersection of efficiency and performance, delivering up to 94.1% efficiency with both 80 PLUS® Platinum and Cybenetics Platinum certifications. This premium rating ensures lower power consumption and cooler operation, making it the ideal PSU for serious gamers, content creators, and PC enthusiasts seeking energy savings and thermal control. Its single 12V rail handles peak power spikes with ease, ensuring rock-solid stability under any load.
Semi-Passive Zero-RPM Cooling for Total Silence
The Power Zone 2 850W incorporates a Pure Wings 3 140mm fan that intelligently remains off under low load and only spins when necessary. This zero-RPM mode ensures a completely silent experience during idle or light use. Even when the fan activates, its custom design and 2–5 minute spin-down cycle prevent frequent on-off noise, enhancing acoustic comfort. The fan’s durable rifle bearing and wide diameter ensure both low noise and superior airflow across components.
Ready for the Future with Advanced Tech and Design
Featuring full ATX 3.1 and PCIe 5.1 compatibility, Power Zone 2 850W includes a native 12V-2x6 connector—angled at 90° for modern cable management. This ensures flawless operation with next-gen GPUs and total adaptability with current hardware. Internally, high-quality LLC technology improves voltage regulation and ripple suppression, while externally, a distinct mesh-front design and clearly marked ports make this PSU as stylish as it is functional—backed confidently by a 10-year warranty.
