Modular power supply unit

A method comprising:

• determining, by a control unit disposed in a modular power supply unit connectible to a host circuit board via an output connector, a power demand code corresponding to the host circuit board based on signals detected on one or more ID pins of the output connector of the modular power supply unit;
• identifying, by the control unit, a power setting, from a plurality of power settings, corresponding to the host circuit board based on the determined power demand code;
• and
• causing, by the control unit, the voltage regulator to generate the electrical power at the identified power setting.

A non-transitory machine-readable medium storing instructions executable by a control unit, the instructions comprising:

• instructions to determine a power demand code corresponding to a host circuit board removably connected to a modular power supply unit based on signals received at on one or more ID pins of an output connector of the modular power supply unit;
• instructions to identify a power setting, from a plurality of power settings, corresponding to a host circuit board based on the determined power demand code;
• and
• instructions to cause a voltage regulator to generate the electrical power at the identified power setting.
