System and method of utilizing power supply units

A chassis, comprising:

• an information handling system (IHS) comprising a plurality of components;
• and
• a first power supply unit (PSU) comprising:
• at least one processor;
• a power controller device;
• a power supply controller coupled to a current source;
• and
• a memory medium, coupled to the at least one processor, that stores instructions executable by the at least one processor, which when executed by the at least one processor, cause the first PSU to:
• provide power at a first voltage to the IHS;
• determine if the IHS utilizes power at a second voltage greater than the first voltage, wherein the determining comprises the power supply controller (PSC) communicating with the current source to provide a first current to a resistor in the IHS and measuring the voltage across the resistor;
• if the IHS utilizes power at the second voltage:
• determine if the first PSU is configurable to provide the power at the second voltage;
• wherein
• if the first PSU is configurable to provide power at the second voltage, communicate with the power controller device to provide power at the second voltage to the IHS, wherein the second voltage is associated with providing power to one or more graphics processing units (GPU)s;
• and
• if the first PSU is not configurable to provide power at the second voltage, provide information indicating that the first PSU is not configurable to provide power at the second voltage;
• and
• if the IHS does not utilize power at the second voltage:
• determine if the first PSU is configured to provide power at the first voltage;
• if the first PSU is configured to provide power at the first voltage, provide power at the first voltage to the IHS;
• and
• if the first PSU is not configured to provide power at the first voltage, provide information indicating that the first PSU is not configured to provide power at the first voltage.
