Techniques are described for determining whether power from a first power source is unavailable to a power supply module. In response to determining that power from the first power source is unavailable, the techniques de-couple the first power source from one or more components of an electronic device connected to an output of the power supply module with one or more de-coupling components of the power supply module that connect an automatic transfer switch (ATS) of the power supply module to an output of the power supply module. Subsequent to de-coupling the first power source from the one or more components of the electronic device, the techniques de-couple a power supply module from the first power source. The techniques couple the power supply module to a second power source for delivering power to the one or more components of the electronic device.
