Warning
: To prevent damage to your power supply or mother-
board, please use a power supply that contains a 24-pin and
two 8-pin power connectors. Be sure to connect these power
connectors to the 24-pin and the two 8-pin power connectors on
your motherboard for adequate power supply to your system.
Failure to do so will void the manufacturer warranty on your
power supply and motherboard.
