This command creates power supplies where the number of power supplies are minimized, assigning the same power supply to multiple runs where possible.

The level of granularity for this power supply loading option is the run. A run is defined as modules that are connected by wires. Using this option, you can have a letter that is split between two or more power supplies.

In this example, the Y is split between two 40W power supplies. The use of colored power supplies help see how this is loaded.
