OK, this model is capable of supplying 865 Watts according to the manufacturer's specifications.

LOADPCT : 39.0 Percent Load Capacity

You're at 39% of 865 Watts, or about 338 Watts. Multiply that by 24 hours a day, 30 days in a month, divide by 1000 and it seems your computer is using 243.4 kWh in a month. (Assuming the above is an "average" load on your UPS.) Check your last electricity bill to see how much you pay per kWh and you'll know exactly how much your computer is costing you per month. AFAICT, about 10 cents per kWh is a reasonable estimate in North America, so I'd guess that running your computer 24/7 is costing you less than $25/month. That's a pretty small savings compared to your overall bill, even if you got rid of the computer entirely.
