Now to answer the exact questions: A 1000w PSU rated at 90% efficiency at full load will draw 1111w of 120v AC from the wall. This 1111w AC will be converted at 90% to 1000w DC and the rest will be lost in heat. But remember that it is most likely that efficiency at full load is much lower than 90%.
