Actually, I think there's a technical reason why they don't say 1500W 
instead of 1500VA.  And if you look at the specs for the 1500VA unit, it 
doesn't work out to 1500W.

http://www.apcc.com/resource/include/techspec_index.cfm?base_sku=SUA1500

Output Power Capacity 980 Watts / 1440 VA
Max Configurable Power 980 Watts / 1440 VA
Nominal Output Voltage 120V

I don't remember enough of my electrical stuff to say why (it has to do 
with DC to AC conversion... I think... and maybe some RMS stuff?).
