I’m new in this forum.
Please imagine this situation. You want to power one computer with multiple connected GPUs but you don’t have a single PSU able to provide enough power to the whole system. But you do have another PSU laying around and the power of both combined would meet the computer power requirements. None of those PSUs cannot even power the CPU, disks, etc, AND each of the GPUs at the 75W max power draw that a PCI-e connector allows.
In this case, the 2nd PSU could provide enough power just for the GPUs through the additional 12V connectors on the GPU boards.
Would this work? The load balancing would be automatic or some extra hardware would be necessary to manage that? Thanks.
