The be quiet! Dark Power 14 is a 1000-watt power supply designed for high-performance computer systems that require a stable and efficient power supply. This power supply features an 80 Plus Platinum certification and achieves up to 94 percent energy efficiency under typical loads, reducing power consumption and heat generation. It utilizes a fully modular cable management system, allowing users to connect only the cables needed for their specific configuration, resulting in clean builds and improved airflow. The unit integrates high-quality Japanese capacitors that ensure long-term reliability and stable voltage regulation even under demanding conditions. The advanced thermal management includes a 135mm Silent Wings fan with fluid dynamic bearing technology, which operates quietly while providing effective cooling, with a zero-RPM fan mode at low to moderate loads for completely silent operation. Comprehensive protection circuits safeguard against overvoltage, undervoltage, overcurrent, overload, short circuit, and overheating. The power supply supports modern graphics cards with multiple PCIe connections and is compatible with ATX 12V v2.52 standards. All cables are sleeved for durability and easy routing, with flat cable designs where applicable to enhance cable management. The dimensions are 150 mm in width, 86 mm in height, and 180 mm in depth, fitting most standard ATX cases. The operating temperature range is between 0 degrees Celsius and 50 degrees Celsius with power reduction above 40 degrees Celsius. The weight is approximately 2.2 kg. This power supply is designed for gaming PCs, workstations, and other high-end computing applications where reliable power delivery and quiet operation are essential.
