CPU
If you will not be using an ATX power connector,
make sure that pins 2-3 of CN20 are closed.
1. Make sure that you unplug your power sup-
ply when adding or removing expansion cards
or other system components. Failure to do so
may cause severe damage to both your CPU
card and expansion cards.
2. ATX power supplies may power on if certain
motherboard components or connections are
touched by metallic objects.
Make sure that the ATX power supply can take
at least a 720 mA load on the 5 V standby lead
(5VSB). If not, you may have difficulty powering
on your system and/or supporting the "Wake-
on-LAN" function.
