This depends on the size of the UPS. In every datasheet the maxium capacity is given in Watt and VA. Most devices like PC's, printers etc are using Watts. When selecting appropriate UPS for your load, you need to consider not only nominal power consumption but also maximum power consumption, peaks, in-rush currents and even harmonic distortions. On top of that a safety margin is advised. We suggest not to aim to connect more than 75% of the nominal Watt power capacity of the UPS.
