How much does my PC or projector consume power for real?

PC - has 350W PSU
Projector - power input label shows 350W
Audio/Video Receiver - power input label 120V-240V 650W

So total power consumption should be 1350 Watt.

I connect all this to my UPS rated 1300 Watt and UPS shows only 35% load which is like 455 Watt. Even if I disconnect UPS from the main and UPS runs on batteries, it shows 35% and 15min remaining backup.

So could it be that the all my equipment actually uses only 455 Watt of power?
