ATX Power Connector

There are a 20-pin main power supply connector(JPW1) and an 8-pin CPU PWR connector (JPW3) on the moth- erboard. These power connectors meet the SSI EPS 12V speciﬁcation. The 4-pin 12V PWR supply is required to provide adequate power to the sys- tem. The UIO PWR, located at J11, is also required for the UIO slots. For the 8-pin PWR (JPW3), please refer to the item listed below. See the table on the
