Replace cables
The cables that you connect to the new motherboard depend on the type of DC power cable that was used on the
motherboard you removed.
To discover which cables to use, look at the DC power cable connector on the old motherboard. If it has 24 pins, you
can use all the original cables on the new motherboard. Note, however, that the location of the connectors is different on
the new motherboard. Refer to the following illustration for details.
