ATXPR1: ATX Power Input Connector
Caution
If the power supply connectors are not properly attached to the ATXPR1 connector, the
power supply or add-on cards may be damaged.
Attach the connector from the power supply
to the ATXPWR1 connector here.
Remember you have to push the connector
from the ATX power supply firmly to the
end with the ATXPWR1 connector, insuring
that you have a good connection.
Note: Watch the pin position and the
orientation
CPUFAN and CHAFAN Headers
Attach the connector from the individual
CPU fan to the header named CPUFAN, and
attach the connector from the chassis fan to
CHAFAN header.
You must attach the CPU fan to the
processor, or your processor will work
abnormally or may be damaged by
overheating. Also, if you want the computer
case’s internal temperature to be kept steady
and not too high, you had better connect the chassis fan.
Note: Watch the pin position and the orientation
