Free Shipping
Main Highlights
- Dark Power 14 1200W is certified with 80 PLUS Titanium and Cybenetics Titanium for a stunning energy efficiency rating of up to 95.42%. This provides lots of benefits for a high-end systemincluding less power consumption and an overall cooler and quieter operation.
- Dark Power 14 1200W is an ATX 3.1 PSU and comes with both native integration of the two 12V-2x6 connectors for next-generation PCIe 5.1 graphics cards and 4 PCIe 6+2-pin connectors for support of current-gen GPUs. This makes the PSU extremely versatile and perfect for current and future high-end systems.
- A button on the rear of the power supply allows switching between a balanced active cooling modewhere the Silent Wings fan spins all the timeor a semi-passive modewhere the fan does not spin under low load and only starts when additional cooling is required for more demanding operations. A post-ventilation setting keeps the fan spinning after cooling down for a short period of 25 minutes to prevent frequent and noisy starts and stops.
- A large heat sink connects to the parts of the power supply that need the most cooling and dissipates a large portion of the heat. Even though a Titanium efficiency power supply does not generate as much heatactive cooling is required to prevent overheating issues under high load. Nothing less than the very best fan of be quiet! cools Dark Power 14 1200W. Being integrated directly into the heat sinkthis high-end fan is immune to vibrations and sits unshakably. A 6-pole fan motor and fluid-dynamic bearing ultimately make for exceptionally long lifetime and minimal power consumption.
- Dark Power 14 1200W is particularly suitable for overclocking. With the simple push of a buttonyou can manually switch between multi-rail and single-rail mode. This gives you full overclocking control between the default four 12V-rail mode and the alternative massive single-rail operation.
- Dark Power 14 1200W is state-of-the-art technology. With an Active Rectifier and full bridge LLC technology it offers some of the most advanced technologies availableresulting in higher efficiencybetter regulation and lower ripple noise for an incomparably stable operation.
- Each component in Dark Power 14 1200W is carefully selected. That is why we have exclusively used high-quality Japanese capacitors for this PSU. They are rated to 105°Censure stabilityreliabilityand a long operating life.
- Modularsleeved cables measuring up to 120cm in length simplify component installation and reduce annoying clutter. This results in increased airflow and improved cooling in even the largest PC cases.
