Super X12SDV-4C/8C/10C-SPT4F User's Manual
1.6 Power Supply
As with all computer products, a stable power source is necessary for proper and reliable
operation. It is even more important for processors that have high CPU clock rates.
The X12SDV-4C/8C/10C-SPT4F motherboard supports both +12 V DC and ATX power input.
Either option requires an 8-pin 12 V connection to the JPV1 header, with an ATX power input
requiring an additional connection using PN: CBL-PWEX-1063 between header PJ1 and the
24-pin power connector of an ATX power supply. PJ1 allows motherboard control of the 5
VStby, power on, power good, and ground signals from the ATX power supply. Refer to the
diagram below for the proper connection to PJ1 for ATX power input.
It is strongly recommended that you use a high quality power supply that meets ATX power
supply Specification 2.02 or above. It must also be SSI compliant. (For more information,
refer to the website at http://www.ssiforum.org/). Additionally, in areas where noisy power
transmission is present, you may choose to install a line filter to shield the computer from
noise. It is recommended that you also install a power surge protector to help avoid problems
caused by power surges.
