be quiet! Unveils Dark Power Pro 14 IO: High-End PSU Controlled via Software

German hardware manufacturer be quiet! has introduced its latest high-end power supply, the Dark Power Pro 14 IO. The defining feature of this model is software control via a USB-C port, allowing users to switch between semi-passive and active fan modes as well as toggle between Single-Rail and Multi-Rail configurations. The unit carries an 80 Plus Titanium certification.

The IO in the product name refers to the integration with the manufacturer's IO Center software suite. Through the USB-C connection, users can monitor power consumption and fan speed, while the dashboard also estimates electricity costs based on usage data. The software interface enables switching between a semi-passive mode (where the fan remains stationary under low load) and continuous active cooling.

From a technical standpoint, the PSU utilizes Japanese capacitors rated for operation up to 105 °C and incorporates an Active-Rectifier system alongside Full-Bridge-LLC technology to ensure high signal stability and efficiency. For graphics card connectivity, the unit provides two native 12V-2x6 ports certified for PCI Express 5.1 standards, supplemented by four standard 6+2-pin connectors.

The modular cabling system features sleeved cables with varying thicknesses to facilitate cable management. The physical dimensions of the unit are 200 × 150 × 86 mm (L x W x H). Pricing is set at €439.90 for the 1,300-watt variant and €479.90 for the 1,600-watt model. The new high-end PSU is scheduled to hit the market in September 2026.
