Hardware Installation
Warning: Follow these precautions to preserve your Motherboard
from any remnant currents when connecting to ATX power supply:
Turn off the power supply and unplug the power cord of the
ATX power supply before connecting to ATX PW connector.
The Motherboard requires a power supply with at least 200 Watts and a
"power good" signal. Make sure the ATX power supply can take at 1.5 A
max current * load on the 5V Standby lead (5VSB) to meet the standard
ATX specification.
Note:
ATX 12V power supply is different from the normal ATX power
supply.
If you use the Wake-On-LAN (WOL) function, make sure the
ATX power supply can support at least 720 mA on the 5V
Standby lead (5VSB).
Please install the ATX power according to the following pin assignment:
