The ATX12V/SSI EPS12V power connector pinout is:
Pin Signal Name Pin Signal Name
1 Ground 5 +12 V
2 Ground 6 +12 V
3 Ground 7 +12 V
4 Ground 8 +12 V
The power supply should match the physical configuration of the chassis. Make sure the
power switch is
Off before assembly.
Before attaching all components, make sure the proper voltage has been selected. Power
supplies often can run on a wide range of voltages and must be set (usually via a switch)
to the proper range. Use at least a 300-watt ATX power supply, which should have built-
in filters to suppress radiated emissions. Power supply voltage depends upon system load.
For example, +12V rating should be matched to the amount of the external load.
Attach the cables from the power supply to the power connector(s) on the motherboard.
ATX-compatible power supplies can have either one or two 20-pin (or 24-pin)
connectors. You can use either one or both power connectors.
For 24-pin /8-pin SSI EPS12V power supplies, plug the connectors into CN1 and CN2 as
illustrated in the following diagram:
