JPW3) on the motherboard. These power
connectors meet the SSI EPS 12V specifi -
cation. In addition to the 24-pin ATX power
connector, the 12V 8-pin CPU PWR connec-

Warning
: To prevent damage to
the power supply or motherboard,
please use a power supply that
contains a 24-pin and two 8-pin
power connectors. Be sure to
connect these connectors to the
24-pin (JPW1) and the two 8-pin
(JPW2,JPW3) power connectors
on the motherboard. Failure in do-
ing so will void the manufacturer
warranty on your power supply and
motherboard.
