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 (JPW3) and the two 8-pin (JPW1,JPW2)
power connectors on the motherboard. Failure in doing so will void the manufacturer
warranty on your power supply and motherboard.
