Peripheral device expansion card system

A peripheral device expansion card system, comprising:

• a card base;
• and
• a card expansion bus connector that is located on the card base, that is configured to couple to a system board, and that includes:
• at least one power pin;
• a system power reporting device that is located on the card base, coupled to the at least one power pin, and configured to:
• receive power from a computing system via the at least one power pin;
• and
• generate a power reporting signal from the power received via the at least one power pin;
• and
• a card controller device that is coupled to the system power reporting device, wherein the card controller device is configured to:
• identify the power reporting signal generated by the system power reporting device;
• and
• determine a power state of the computing system using the power reporting signal.

A method for determining a computing system power state in a peripheral device expansion card system, comprising:

• receiving, by a system power reporting device that is located on a peripheral device expansion card system and coupled through at least one power connection to a computing system, power from the computing system via the at least one power connection;
• generating, by the system power reporting device using the power received via the at least one power connection, a power reporting signal;
• identifying, by a card controller device that is located on the peripheral device expansion card system, the power reporting signal generated by the system power reporting device;
• and
• determining, by the card controller device using the power reporting signal, a power state of the computing system.
