The output "wattage" depends on the discharge time. The output energy can be calculated from the data you've provided, since it is equal to the input energy: 12V × 3A × 30s = 1.08 kJ.

I wrote, "The output "wattage" depends on the discharge time." So you need to know the time it takes your capacitors to discharge. Follow the link, and you'll see how to use that information to do the calculation.
