High efficiency:
The power supply series from STRAIGHT POWER dispose of a very high degree of efficiency. This
helps them to reduce the costs of electricity that accumulate within a year when there‘s a high
rate of operation.
A high efficiency means that the power supply can
convert the incoming alternative current into direct
current with a lower level of losses. This leads to
a lower amount of warmth loss, which then has a
positive effect on cooling the power supply. Power
supplys that feature as high a rate of efficiency as
is exhibited by the STRAIGHT POWER
E7
SPECIAL EDI-
TION, can thus be operated with an extremely slow
moving and thus, very quiet fan. An extremely low
development of noise is the result of this continually
technical advancement.
Economical:
The STRAIGHT POWER
E7
SPECIAL EDITION corresponds to the current guidelines 2002/95/EG (RoHs and WEEE
directives) issued by the European Union.
An environmentally conscious manner of production and the usage of materials that do not include harmful
substances that are dangerous for the environment are guaranteed with be quiet! products. In this way, both
we the manufacturer and you the consumer actively help in making an important contribution to the protection
of our environment.
Voltage stability:
The STRAIGHT POWER
E7
SPECIAL EDITION dispose of a first-class stability in supplying your valuable componen-
ts with electricity. This is also created by the usage of high quality components. As such, output voltages are
kept very close to the optimal nominal value, which is very important for a higher demand on performance.
Warmth-dependent air velocity control:
The be quiet! STRAIGHT POWER
E7
SPECIAL EDITION make use of a very precise air velocity control. This auto-
matic control not only controls the fan in the power supply, but can also control the case fan that can be con-
nected to the power supply. The application is rather simple: only the case fans that are usually equipped with
a 3 pole and/or 4 pole connector must be connected with the respective connections onto the power supply
The speed of the fan is regulated depending on the warmth development in the power supply. If the tempe-
rature increases, the fans automatically begin to turn faster in order to ensure a quick and effective cooling
within the case. The cooling that is quickly created then contributes to the longer lifespan of its components
and the power supply.
When connecting individual fans to the power supply, please ensure that these fans do not have their own
thermal sensors or potentiometers.
