otherwise, condensation can build up in the power supply.
3. ADVANTAGES AND SPECIFICS OF YOUR NEW POWER SUPPLY
High efficiency:
The power supply series from Straight Power
have a very high degree of efficiency. This helps
have reduce the cost of electricity that at 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 heat, which then has
a positive effect on cooling the power supply. Power supplies that feature as high a rate of efficiency
as is exhibited by the Straight Power series, 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 power supplies of the Straight Power series corresponds to the current guidelines 2002/95/EG

The speed of the fan is regulated depending on the warmth development in the power supply. If the
temperature increases, the fans automatically begin to turn faster in order to ensure a quick and
effective cooling within the case.
