2.2.2.4 Power Supply Connectors
The board has the following power supply connectors:
• Main power – a 2 x 12 connector.
• Processor core power (2) – two 2 x 4 connectors. These connectors provide
power directly to the processor voltage regulator and must always be used. Failure
to do so will prevent the board from booting.
• Auxiliary PCI Express graphics power – a 1 x 4 connector. This connector
provides the required additional power when using high power (75 W or greater)
add-in cards the PCI Express x16 bus add-in card connectors. See
Figure 1 for
location.
CAUTION
If a high power (75 W or greater) add-in card is installed in any of the PCI Express
x16 bus add-in card connectors, the Auxiliary PCI Express graphics power connector
must be used. Failure to do so may cause damage to the board and the add-in cards.
