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 P4-645DX DRAGON Ultra requires a power supply with at least 250
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).
