Configuration
ATX 12V 2.0 compliant - with a 24-pin ATX main power connector,
dual 12V rails (12V
1
and 12V
2
) and an 8-pin EPS server style 12V
power connector. The +12V power connector enables the delivery of
more +12VDC current to the processor’s Voltage Regulator Module
(VRM). It is preferable to use the 8-pin power (rather than the usual
4-pin power); connect to CN9 as shown below.
