7. be quiet! Dark Power 14

Dark Power 14 1200W is certified with 80 PLUS Titanium and Cybenetics Titanium for an impressive energy efficiency of up to 95.4%. This brings many benefits for 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 2 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 perfectly suited for current and future high-end systems.

A button on the back of the power supply allows you to switch between a balanced active cooling mode, in which the Silent Wings fan is constantly running, and a semi-passive cooling mode, in which the Silent Wings fan is constantly running.mode, in which the fan stands still and only starts when additional cooling is required for more demanding applications. After-ventilation ensures that the fan continues to run for another 2-5 minutes to cool down in order to avoid frequent and noisy 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 most of the heat. Even though a titanium efficiency PSU does not generate as much heat, active cooling is necessary to avoid overheating problems under heavy load. 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. A 6-pole fan motor and fluid-dynamic bearings ensure an extremely long service life and minimised power consumption.

The Dark Power 14 1200W is particularly suitable for overclocking. A simple push of a button switches manually between multi-rail and single-rail mode. This gives you full control over overclocking between the standard four 12 V rail mode and the alternative massive single-rail mode. more
