Desk power calculator
Quick answer
A 15 A, 120 V branch circuit carries 1,440 W continuously once derated to 80 percent, and a fully loaded desk rarely passes 600 W, so the limit is almost never the circuit. It is the outlet count and the surge rating, and a surge protector is a consumable that degrades with every event it absorbs.
The circuit arithmetic and the UPS power factor are standard. Typical device draws are conventions for planning, and your own equipment labels are the real numbers.
UPS sizing: VA = watts / 0.6. Continuous circuit capacity = 15 A x 120 V x 0.8 = 1,440 W.
