Need to know the total wattage. Once you know your wattage you can calculate your amperage. I would say a 10/3 SOOW will be fine. I personally would not run 120V up the tower but instead just use a APC below. We have used the Tripplite APS1012SW. You add your own batts which I prefer because i can pick based on the backup runtime i desire. Also make sure you add something like a tycon din web monitor piece so you can keep an eye on voltages. I can help you with this just hit me off list.
