Warning: To prevent damage to the power supply or serverboard, please use a power supply that contains a 24-pin and two 8-pin power connec- tors. Be sure to connect these to the 24-pin and the two 8-pin power con- nectors on your serverboard to supply adequate power to your system. Failure to do so will void the manufacturer warranty on the power supply and serverboard.
