5.3 Connector from Motherboard to Storage Devices
ā Reference
Other components that require both 12V and 5V power like SATA Storage and Optical
drives will now need to get their power from the motherboard. The motherboard will
provide the voltage regulator that converts 12V power into 5V. This connector needs
to be Black for both the cable and board connector to easily identify that power is
coming out of the power and is not a connector that needs power from the power
supply.
This is included in the power supply design guide to provide an industry standard
connection from motherboard to these Storage and/or other devices using these
connectors.
5.3.1 Motherboard Connector
Motherboard needs to provide power for Storage devices because they need both 12V
and 5V. The motherboard is recommended to provide power to either 4, 6, or 8
storage drives. Current and near future platforms support 6ā8 SATA connections.
Based on market, board size and cost considerations the amount of storage drives
supported needs to be considered. Based on per storage drive max requirements of
12V @ 2-2.5 amps and 5V @ 1 amp, below are details for two options. If per drive
power increases, then number of drives per connector would also change.
Two connector options listed below to support 2 drives or 4 drives per connector
based on motherboard need. Both connector options follow the 3 mm ATX12VO
SATA Power Header dual row vertical through hole product type. These connectors
must support 5A per pin.
