APM and ACPI system status, energy-saving modes
32 - English A26361-D1562-Z121-1-6319
Mainboard current requirement
You require a Pentium4 power supply nit as per the ATX12V specification for this mainboard. If you
do not have a PC from Fujitsu Siemens Computer, make sure that the power supply unit provides
the required amperages.
Resource Voltage Maximum
difference
Maximum current
ATX12V power supply +12 V ±5 % 9 A
ATX12V power supply -12 V ±10 % 0.05 A
ATX12V power supply +5.0 V ±5 % 6.5 A
ATX12V power supply +3.3 V ±5 % 4.0 A
Standby voltage of power supply unit +5.0 V SB ±5 % 0.5 A
The specifications apply to the onboard components and represent the least favourable case. In
addition, at least 350 mA is required for PCI on 3.3 V, and 500 mA per connected device for USB on
5 V.

The power supply unit must provide sufficiently loadable 5 V standby voltage.
To use the WOL functionality the power supply must provide a 5 V auxiliary voltage (5VSB) of at
least 1 A.
