Nothing goes in the top; that's where UU-Matter goes when it is produced. Ideally, you'd use either several HV Solar Arrays or a Nuclear Reactor or two, with excess power going to an MFSU. The Mass-Fab can accept up to high voltage, so there should be no reason to use Transformers unless your Nuclear Reactor produces extreme voltage.
