The be quiet! Dark Power 14 850W is a high-end ATX desktop computer power supply built for demanding systems that need both maximum efficiency and near-silent operation. With 80 PLUS Titanium certification reaching up to 95.57% efficiency, it converts more power into usable output and generates less heat than standard units.

Description

Titanium Efficiency Meets Near-Silent Cooling

850W output with ATX 3.1 form factor — ample headroom for high-end CPUs and multi-GPU configurations
80 PLUS Titanium efficiency rating reduces energy waste and operating temperatures
135mm Silent Wings fan with switchable semi-passive mode for virtually inaudible operation under light loads
Aluminium heat sink supports the semi-passive cooling concept and extends component longevity
Modular cable management keeps builds tidy and airflow unobstructed

An ideal choice for high-performance gaming PCs, content creation workstations, and enthusiast builds where low noise and stable power delivery under sustained load are non-negotiable requirements.
