Practically speaking Cisco came to the rescue for me. There are 2 Cisco solutions I use: 1. Cisco power brick from 1700's series routers. 2. Gutted Cisco chassis from 2600's series routers.
Both supply more than sufficient power for a thunderbolt. I personally like option 2 as I can rack mount the TB.

What ever you have should be well regulated, at least on the +12 line.
