A Detailed Look
The be quiet! Straight Power 10 800W CM power supply enclosure is painted matte black with white lettering and measures 160mm (6.3”) 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 2100 rpm at 12 VDC. The fan speed starts out very slow and quiet and gradually ramps up as the load increases.
The front panel includes a fixed 24-pin ATX power cable and seven connectors for the modular cables, all nicely labeled.
The Straight Power 10 power supply comes with a basic assortment of cables; one fixed 24-pin ATX power cable and seven modular cables. All of the cables are covered with black plastic braiding.

Here are a few pictures showing the layout and components inside the be quiet! Straight Power 10 800W CM power supply. Be quiet! is once again using FSP Group as the OEM for the Straight Power 10 CM Series. The layout and build quality appears good.
FSP is using an improved integrated circuit power conversion design that features Active Clamp and Synchronous Rectifier technology along with DC-toDC voltage regulators located on the main PCB to provide good voltage regulation and high efficiency.
All of the components are rated for 105°C operation but instead of top-tier Japanese made capacitors, FSP is using mostly Teapo electrolytic and solid polymer capacitors.
