How much power can a UPS provide?
If you're just running one computer, then you might get away with a smaller one. A UPS's power capacity is measured in Voltage-Amps (rather than Watts, which measures the power consumed rather than supplied). As a general rule, a UPS can support a load of around 9kW for every 10kVA.
How much current does a UPS draw?
UPS systems are often “sized” by a kW (kilowatts) and/or a kVA (kilo-volt-amperes) rating. For example, a 1 kVA UPS means its circuitry can handle 1,000 volt-amperes .
