A UPS has two ratings and the lower one is the limit. This unit is rated 750 VA and 375 W, so the equipment plugged into its battery outlets should draw no more than about 300 W if you want the usual 20% headroom. How to size a UPS.

Its weighted efficiency of 98.5% compares with a median of 98.7% across 105 certified units within 25% of its capacity. With nothing plugged in it still draws 3.1 W, about $3.53 a year at 13¢/kWh just to stand ready.
