Key Features

  • Dark Power 14 1200W is certified with 80 PLUS Titanium and Cybenetics Titanium for impressive energy efficiency of up to 95.42%. This brings many benefits to a high-end system, including lower power consumption and overall cooler and quieter operation.
  • Dark Power 14 1200W is an ATX 3.1 power supply with native integration of the two 12V 2x6 connectors for next-generation PCIe 5.1 graphics cards and 4 PCIe 6+2-pin connectors for current generation GPUs. This makes the power supply extremely versatile and perfect for current and future high-end systems.
  • A button on the back of the power supply switches between a balanced active cooling mode in which the Silent Wings fan is constantly running, and a semi-passive mode where the fan stops and starts only when additional cooling is required for more demanding applications. A re-ventilation ensures that the fan continues to run for 2-5 minutes to cool down to avoid frequent and loud starting and stopping.
  • A large heat sink is connected to the parts of the power supply that need to be cooled the most, and dissipates much of the heat. Even if a titanium efficiency power supply does not generate as much heat, active cooling is necessary to avoid overheating problems under high loads. Only the best fan from be quiet! cools the Dark Power 14 1200W. The high-end fan integrated directly into the heat sink is vibration-free and sits absolutely firmly.
  • The Dark Power 14 1200W is particularly suitable for overclocking. With a simple push of a button, you can manually switch between multi-rail and single-rail modes. This gives you full control over overclocking between the standard four-12V rail mode and alternate massive single-rail operation.
  • Dark Power 14 1200W offers pretty much the latest of the new. With an active rectifier and full-bridge LC technology, it features some of the most advanced technologies on the market, resulting in higher efficiency, better control and lower hum noise for unparalleled stable operation.
