BENEFITS AND SPECIAL FEATURES OF YOUR NEW POWER SUPPLY

Our DARK POWER PRO
P8
Series power supplies have a very high efciency level of up to 92%.
This helps reduce dissipation loss.
High efciency means that the power supply can
convert the incoming AC current into direct current
with very little loss. This also reduces the lost heat
and thus has a positive effect on cooling the power
supply. Power supplies that feature a high level
of efciency like the DARK POWER PRO
P8
Series
can therefore be operated with an extremely slow
running and thus very quiet radiator fan. Extremely
low noise emission is the result of ongoing technical
advances.

Series power supplies comply with the current 2002/95/EG (RoHs and WEEE) direc-
tives issued by the European Union.
An environmentally conscious production process and use of materials that avoid environmentally harmful
substances environment are guaranteed for be quiet! products. In this way, we as the manufacturer and you as

DARK POWER PRO
P8
Series power supplies offer best-of-class voltage stability for your components. This is
also guaranteed by the use of high quality components. Output voltages are maintained at levels very close to
specications; this is particularly important for high performance requirements.

be quiet! power supplies from the DARK POWER PRO
P8
Series offer very precise thermal fan control. This auto-
matic system not only controls the power supply itself, but can also control other fans connected to the power
supply’s “FAN” ports.
The fan speed is driven by the heat development in the PC case and controlled by the power supply. If the
temperature increases, the fans automatically begin to turn faster in order to ensure quick and effective
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 ther-
mal sensors or potentiometers.
The fan control system generates a ramp-up burst signal. This short burst at a high voltage level ensures that
all the connected fans in the case will start.
Important: Connect only one fan per cable.
