A Detailed Look
The be quiet! Dark Power Pro 11 750W power supply enclosure is painted matte black with white lettering and measures 180mm (7.1”) long. The back panel includes an On-Off switch, AC receptacle and a large honey-comb grill area for good exhaust airflow. The fan grill is made up of multiple parallel bars for minimal restriction and good airflow.
The power supply uses a 135mm SilentWings3 fan for cooling (BQ SIW3-13525-HF) that incorporates fluid dynamic bearings for quiet operation and long, reliable life. The sculpted fan blades are designed to reduce air turbulence and noise. The fan is rated for 0.56A and 1800 rpm at 12 VDC. The 6-pole fan motor and IC motor control circuit produce smooth low-speed operation and reduced noise for exceptionally quiet operation.
Up to four case fans can be connected to the power supply and will follow the same fan speed profile. The white 3-pin connector in the bottom left corner is for attaching either the overclock jumper or the overclocking switch. When the overclocking feature is enabled (attaching the overclock key or turning the overclock switch On) converts the power supply from multi-rail to single rail operation on the +12V output.
The front panel includes a fixed 24-pin ATX power cable and fifteen connectors for the modular cables, all nicely labeled.
The Dark Power Pro 11 power supply comes with an excellent assortment of twelve fully modular cables for easy installation and clean builds. All of the cables are covered with black plastic braiding.

Here are a few pictures showing the layout and components inside the be quiet! Dark Power Pro 11 750W CM power supply. Be quiet! is once again using FSP Group as the OEM for the Dark Power Pro 11 Series. The layout and build quality appears very good.
FSP is using a modern, high-performance half-bridge LLC, Synchronous Rectification power conversion design along with DC-to-DC voltage regulators located on a daughter card to provide good voltage regulation and high efficiency.
All of the capacitors are rated for 105°C operation and the two primary filter caps are made by Nichicon, a large Japanese manufacturer and rated for 330 uF, 420V, and 105°C.
