Connecting Cables

Power Connectors

A 24-pin main power supply connector
(JPWR1), and four 8-pin CPU power con-
nectors (JPWR2/JPWR3/JPWR4/JPWR5)
are located on the motherboard. These
power connectors meet the SSI EPS 12V
specification and must be connected to your
power supply to provide adequate power to
the system. See the tables on the right for
pin definitions.
Warning: To provide adequate power sup-
ply to the motherboard, be sure to connect
the 24-pin ATX PWR (JPWR1), and the four
8-pin PWR connectors (JPWR2/3/4/5) to the
power supply. Failure to do so may void the
manufacturer warranty on your power supply
and motherboard.
