Ozzy,
Mine is 1.380KVA. I would get the highest rated unit you can afford depending on the requirements of your system. I would be careful to choose a unit that is rated at least twice the cumulative watts of your system -- especially if you have a pre amp and power amp. Go through your system carefully and add up the rated watts, then double that number. This should be the minimum number to run your system safely.
