UPS for 1200W power supply

[Chucke]

Hi!

I've got FSP Aurum Pro 1200W.
What UPS should I buy for that power supply if we assume that it has 100% workload?

See watts to KVA calc: http://www.rapidtables.com/calc/electric/watt-to-kva-calculator.htm

issue: what is the power factor?
see http://en.wikipedia.org/wiki/Power_factor#Power_factor_correction_of_linear_loads

hint: PF ~ 0.75

So I presume I need from 1200 to 1600 VA UPS?

Looks good - - go for the HIGHER number to avoid stressing the UPS.

I see.
Then what about that guy?
http://www.amazon.com/APC-Smart-UPS-SMT1500-1500VA-System/dp/B002MZW5JU
But it has power capacity - 1000W. Should I go for 2200 model?
