You can use a power bar that needs 1500 watts or less.
A wattmeter is used to measure the power of a load.
Not unless the device is running at less than 333 volts.
Yes, less than a 75W bulb.
yes it can
Power - Watt. Energy - Watt Hour. Power factor - no unit. just number less than or equal to 1.
No. It just draws less power.
It isn't more, it is less if bulbs are of the same type.

Power is a quantity, and the watt is its unit of measurement.
yes/no
An incandescent nightlight bulb is either 4 watt or 7 watt. A 4 watt bulb uses 1/25th (0.04) the power of a 100 watt bulb. A 7 watt bulb uses 7/100th (0.07) the power of a 100 watt bulb. There are LED and other types of nightlights that use much less power than this. To find the energy total used multiply the power (in watts) by the total time the light is on (in hours) to get energy (in Wh). If you want kWh divide this by 1000 as a watt is 1/1000th of a kW.

To be safe I would choose about a 700 Watt PSU, definitely no less than a 650 Watt model.
James Watt measured electrical power
Watt is a unit of power. 1 Watt = 1 Joule/second; joule is the unit for energy.
