Abstract: Embodiments of systems and methods for performing Power Supply Unit (PSU) firmware updates without interrupting a user's datapath are described. In an illustrative, non-limiting embodiment, an Information Handling System (IHS) may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the IHS to: cluster a first set of PSUs into a first logical group and a second set of PSUs into a second logical group, update a first PSU of the first logical group with a firmware image, after the update, assign the first PSU to the second logical group, assign a second PSU of the second logical group to the first logical group, and update the second PSU with the firmware image.
