1. A computer system for detecting if one or more processing devices have separately sourced power feeds comprising:
one or more processing devices;
one or more memory devices communicatively and operably coupled to the one or more processing devices; and
a power management tool communicatively and operably coupled to the one or more processing devices, the power management tool configured to:
determine transmission of a message in a first electric path;
monitor for an acknowledgement to the message in a second electric path, the second electric path different from the first electric path; and
determine, based on whether the acknowledgment to the message is detected in the second electric path, whether there is electrical isolation between the first electric path and the second electric path.
