If I attach enough equipment to my UPS to exceed theoretical max amps but stay under the listed Watt Rating and VA Rating, how will that work out?

How would the UPS internally deal with this issue of an 8.1 Amp load? The maximum current load can be derived from the UPS's maximum impedance load - the VA value. 1500VA ÷ 120 V = 12.5A maximum ...

If I attach enough equipment to my UPS to exceed theoretical max amps but stay under the listed Watt Rating and VA Rating, how will that work out?

As we can see, my total load falls within the Watt Rating and VA Rating ; however, if we divide the Watt Rating of 900 W by the assumed output voltage of 120 V this leads me to believe that the UPS is ...

If I attach enough equipment to my UPS to exceed theoretical max amps but stay under the listed Watt Rating and VA Rating, how will that work out?

Almost certainly the only difference will be run time. Loaded that heavily, your UPS will have a very short run time, considerably less than half of what it would have with the lighter load (576 watts,...
