That will depend on the UPS specifications (e.g. output VA rating, efficiency) as well as the load's reactance.
There are UPSs with output VA ratings from as low as 100 VA to several hundreds of thousands of VA (this is more than 3 orders of magnitude in equivalent wattage). The higher VA rated UPSs must by the electrical code be wired directly (they cannot be plugged in and they weigh several tons so they can't be moved either) by a licenced electrician.
The more efficient a UPS is, the closer the input watts needed will be to the output VA rating, a less efficient UPS will need more watts.
The only way you can get a reasonable estimate of the answer to this question is to read the specifications in the manual for the specific UPS you are interested in or are already using.

How many watts do a 850 VA ups use?
maximum power out put is 500 watts
How many watts does a water purifier need?
It depends on what kind, but normal water purifiers need 300~450 watts per hour.
How many watts of electric on a 13 amp fuse 240 volts?
You need the formula: Amps * Volts = Watts But you get to do the math.
How many volts in 12 mega watts?
Watts = Volts x Amps. 12 megawatts = 12,000,000 watts. You need to know current to calculate the voltage.
How many watts do you need for 26 amps?
6240 watts if it's on a 240 volt circuit. A better answer is to just learn that amps X volts = watts.
How many watts do a 850 VA ups use?
maximum power out put is 500 watts
How you find ups watts?
It is expressed in Volt-Amperes not Watts.
What size of a ups would you need to handle 20 watts?
UPS batteries are typically rated at how many ampere hrs they can supply. IF your 20 Watt device is supplied by 120V then it draws 1/6 amps. (Watts = Amps * Volts for a resistive load). If your UPS were rated for 1 A Hr you could power your device for 6 hours.
How you find ups watts and give detail about VA?
UPS power is not specified in watts.However VA is the equivalent of watts, assuming no phaseshift in the load.
How many watts need for seven ampere's and 120 volt's?
770 watts.
How many amperes in a watt and how many watts in a volt?
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
What kva generator to run 15Hp motor?
1HP = 746 watts 15 HP = 11190 watts = 11.19 kW You would need a generator of at least 13kW. UPS Distributor for 15 Years.
How many watts does a nintendo64 need?
26watts
How many watts does a small car need?
Ignition 30 watts, fans 30 watts, driving lights 30 watts, headlights 100 watts. Total about 200 watts.
How many push ups do you need to do?
it depends on how many you can do
How do you determine Uninterrupted Power Supply size?
The load size in watts is what determines the size of UPS needed. Add up all of the load wattages that you would like to have an uninterrupted power supply. Some UPS units are rated in VA output, for the purposes of this calculation VA is the same as watts. There are many UPS calculators on line if you need any help deciding what to connect to it. Remember the larger the UPS the more the cost is going to be. Read the discuss page for calculator.
What two measurements are use to rate the capacity of ups?
VA and Watts
