Do Step-Down Transformers Increase Total Power Consumption?

For a realistic AC line step-down transformer, power in is a little bit more than power out: it''s not quite 100% efficient, but it should be close. Thus, if you plug a 300W load into a step-down transformer (assuming the transformer is rated for more than 300W), expect it to draw a little more, perhaps 325W - 375W depending on quality of construction.
