Definitely. Each pair of mine on Anker hubs is pulling 30W at the wall. I currently have 6 sticks on 3 hubs and 4 more sticks pre ordered. It would be nice to have a single hub that can run them all at full speed, but it's not looking like such a hub exists.
I have Sipolar A400 with 10 ML2 & another Sipolar A400 with 10 2Pacs. They rate themselves at 12V 10A (120W), but you can't really push them to 120W (more like 100W). I've seen USB HUB that have separate 480W power supply. But if you're getting into that realm and cost, you might as well just buy an Antminer and muffle the sound with an ice chest rig or something.
