Power supply control apparatus and computer product

A non-transitory, computer-readable recording medium storing therein a power supply control program causing a computer to execute a process comprising:

• obtaining a value of power consumed by a specified device to which a plurality of power supply devices supply power;
• and
• determining, based on the obtained power value and a predetermined value obtained from power conversion efficiency of each power supply device among the plurality of power supply devices, a scheme of supplying power to the specified device to be any one among a first scheme in which the plurality of power supply devices supply power and a second scheme in which among a first power supply device and a second power supply device included in the plurality of power supply devices, voltage of power supplied by the first power supply device is made lower than that of power supplied by the second power supply device, whereby the second power supply device supplies power.
