World Class Power Regulation

Fully digital control

The fully digital control (PFC, LLC, SR/12V) results in higher efficiency, better regulation and lower ripple noise. This guarantees an incomparably stable operation. Due to the digital concept the Dark Power Pro 12 can reach a great efficiency over the complete power range, even at low load.

Frameless Silent Wings Fan
Patented fan technology for virtually inaudible operation
The be quiet! Silent Wings fan mounted on a tripod enables maximum airflow and a virtually inaudible operation at ordinary loads. This is thanks to its unique, airflow-optimized fan blade design along with an advanced fluid-dynamic bearing and 6-pole fan motor for less vibration, super-long life and minimal power consumption.

Innovative Cooling Concept
For a longer lifespan
The split fan inlet of the Dark Power Pro 12 1200W is a specially-shaped funnel that increases airflow while reducing unwanted turbulence. The wire-free design inside allows the cool air to reach all components flawlessly which ultimately leads to a longer lifespan.

Ready For Overclocking
Pushing the performance of your PSU to the max
Dark Power Pro 12 1200W is particularly suitable for overclocking, thanks to its strong and stable 12V rails. The overclocking key empowers you with full control for overclocking by manually switching between the default six 12V-rail mode and the alternative massive single-rail operation.

Maximum Convenience
Modular cables
The maximum utility afforded by modular single-sleeved cables of up to 120cm simplifies component installation and reduces annoying clutter. This results in increased airflow and improved cooling in even the largest PC cases.

State-Of-The-Art Digital Technology
Rock-steady signal stability and efficiency
Experience the most technologically advanced power supply be quiet! has ever built! Using an advanced digital full bridge, LLC and Synchronous Rectifier (SR) technology it provides unmatched signal stability and unbeatable power efficiency. It is also equipped with DC-to-DC conversion for tight voltage regulation, even under heavy cross-loading conditions. This ensures reliable operation for the next generation of processors and graphics cards.

Japanese 105° Capacitors
A testament to high quality
Only the best components are used in Dark Power Pro 12 1200W. That is why we have built exclusively high-quality Japanese capacitors into the PSU chassis. They are rated to 105°C which ensures stability, reliability and a long operating life.

Magnificent Appearance
Larger cooling area and new visual aspects
The all-new PSU front and the redesigned funnel-shaped opening uphold the high air circulation abilities. In combination with the individually sleeved cables, the high-quality aluminum case on the outside and the high-end components on the inside make the Dark Power Pro 12 shine from every possible angle.
