Convenient usage and excellent compatibility
User-friendly modular cable management reduces clutter and improves cooling airow. High-quality sleeved
cables of up to 120cm. 2x 12V P8 connections (1x P8 connection and 1x P4+4 connection).
Thanks to a main connector that is expandable from 20 to 24 pins, the Dark Power Pro 11 series is also
downwardly compatible with all current motherboard specications. This power supply does not support

Optimal cooling system
Connect up to four case fans for optimized system cooling, thermally controlled by the PSU.
be quiet! power supplies from the Dark
Power Pro 11 series oer high-precision
thermal fan control. This monitoring
mechanism controls the fans using the
"FAN" connection on the power supply.
Fan speed is adapted to reect the actual
heat levels inside the PC case and power
supply. When temperatures rise, the fans
automatically begin to turn faster in order
to ensure quick and eective cooling
within the case. The fact that cool air is
generated quickly helps to improve the
life expectancy of your components and
the power supply itself. When connecting external fans to the power supply, please ensure that these fans do
not have their own thermal sensors or potentiometers.
The fan control system generates a start-up signal. This short, high-voltage burst ensures that all the connected
fans in the case will start together each time.
Important: Connect only one fan per cable.
Top safety and reliability
Excellent protection for your components (OCP, OVP, UVP, OPP, OTP and SCP). Certied in accordance with
international safety standards�
