I've been surprised how low the power rating of some devices is. My (desktop) PC is 3W in standby. The switch next to it ON is 2W.
Yes, individual devices can be quite low, but in my case, it's death by 1000 cuts... I have 5 managed switches, 2 routers and another 3 access points, 2 NAS, a small server (ESXi host), a couple of smart device hubs, a SIP/DECT gateway, 4 DECT/SIP phones, 3 Echo Shows, 7 Echo/Echo Dots, 2 Xboxes, 2 Nvidia Shields, etc.
My base load is currently 650W, but it will probably still be over 600W when I put my PC to sleep and turn off the lights. I think I need to work on getting down below 500W (I've had it down there before).
