*Note 1: You cannot use both 20-pin power connectors located at J17 (the right
side connector) and JP10 (the left side connector) as input power supply connec-
tors at the same time. Only one connector can be used for input power supply to
the motherboard at one time. *For proper use of these proprietary PWR Connec-
tors, please customize your PWR cables based on the Power Connector Pin-Out
Defi nitions listed on Page 2-14.
*Note 2: The 4-pin Auxiliary PWR Connector is used as a power output to the HDDs
only. *Refer to Pages 2-14, 2-15 for more information on power connectors.
