This command creates a single power supply for the selected letters, or if there is no selection, all the LED objects in the layout. If a group of letters was selected when starting PowerFlow, that group is used. Use this for a smaller letter set or job.

You will have to pre-select the power supply that you want to use from the PS list. To have the system automatically choose the power supply for you, see the next section [[Add_One_Power_Supply_for_All_Letters_with_Auto_PS]].
