At-a-glance


  • 6-pole fan motor and IC motor control for smooth low-speed operation and reduced noise

  • Dark Power Pro 11 1200W is certified with 80 PLUS Platinum and an energy efficiency rating of up to 94%. This provides lots of benefits for your high-end system, including less power consumption and an overall cooler and quieter operation. The standby drain is below 0.1 watts.

  • Dark Power Pro 11 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 manual switching between the default four 12V-rail mode and the alternative massive single-rail operation.

  • Dark Power Pro 11 offers 1200W of continuous power with four independent 12V-rails for excellent signal stability and nine PCI express connectors for multi-GPU systems. Up to four case fans can be connected to, and regulated by the PSU.

  • Experience the most technologically advanced power supply be quiet! has ever built! Using an advanced 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.

  • Full bridge, LLC, SR and DC/DC technology delivers 80PLUS® Platinum power efficiency (up to 94%) and power stability unmatched in its class

  • German product conception, design and quality control

  • Intelligent control for up to 4 case fans

  • Isolation sleeve reduces transmission of vibrations to case

  • Large funnel-shaped fan intake facilitates high airflow with less turbulence

  • Only the best components are used in Dark Power Pro 11 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.

  • Overclocking key switches between four 12V-rails and one massive 12V-rail

  • Premium 105°C-rated Japanese capacitors maximize reliability

  • The decoupled be quiet! Silent Wings 3 135mm fan provides virtually inaudible operation. 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.

  • The fan inlet of the Dark Power Pro 11 1200W is funnel shaped. This causes an increased throughput of air, which results inhigher cooling performance.

  • The maximum utility afforded by extra-long sleeved cables of up to 120cm and modular cable management simplifies component installation and reduces annoying clutter. This succeeds in increasing the airflow and improving the cooling in even the largest PC cases.

  • User-friendly cable management reduces clutter, improves cooling

  • Virtually inaudible SilentWings® 3 135mm fan with fluid-dynamic bearing
