Key Specifications

Near-Silent Operation with Advanced Cooling

The Dark Power 14 850W employs a sophisticated cooling system that can operate in both active and semi-passive modes. The 135mm Fluid Dynamic Bearing (FDB) fan automatically adjusts between 0-2100 RPM based on thermal load, achieving whisper-quiet operation at just 16 dB when cooling demands are low. This makes it ideal for noise-sensitive environments like home offices or media centres.

Exceptional Efficiency and Power Delivery

With 80 PLUS Titanium certification, this PSU achieves up to 93.8% efficiency across all loads, significantly reducing wasted energy and heat generation. The 850W unit provides a combined +12V capacity of 850W across four independent rails, ensuring stable power delivery even under demanding gaming or content creation workloads. The 950W peak power capability offers headroom for brief power spikes.

Comprehensive Protection and Reliability

Built with professional-grade components, the Dark Power 14 includes extensive protection features: over current, over voltage, overheating, overload, short circuit, surge & inrush protection, and under voltage protection. With a Mean Time Between Failures (MTBF) rating of 100,000 hours and compliance with UKCA, TÜV, and FCC standards, this PSU offers exceptional long-term reliability for critical systems.
