13. Technical specifications
•
Operation on mains voltage, 100-240V~, 47-63Hz, automatic adjustment via the power supply unit
•
Output voltages and output currents (also see imprint on power supply unit):
+3.3V=
30A
+5V=
28A
+12V1=
18A
+12V2=
18A
+12V3=
18A
+12V4=
18A
-12V=
0.8A
+5V= standby
2.5A
The power supply unit has four separate +12V=-outputs. This is to avoid an interaction due to high load
currents.
The total current from the four 12V= outputs must not exceed 60A.
The total power from the +3.3V and the +5V branches must not exceed 180W.
The total output power must not exceed 750W.
The power supply unit does not have the "-5V" voltage which former power supply units had (a terminal/
cable is missing in the wide ATX plug at the corresponding spot). Since this voltage is not needed by
the present components, this has no further consequence.
With newer versions of the power supply unit, the level of the output currents could have been modified
by the manufacturer. Note the imprint on the power supply unit.
•
The power supply unit is equipped with connection sockets which can be connected to the corresponding devices
(e.g. hard discs, DVD writers, graphic cards) via the cables included in the delivery.
•
Mains switch on the back of the device
•
Active PFC (Power Factor Correction)
