For me, I would use the USB ports that come on an external monitor (like the Apple 27" Cinema display or others from various companies). The Cinema display provides power to the USB ports all of the time, not just when the monitor is on. That's why I'd choose the one in my external monitor, but since I don't use too many USB ports at one time, I don't need more, and I never bothered looking up more information regarding this topic, so I'm not the best source for information.

On the internet (i have seen them on ebay and do not know if you can get them any were else) you can get a 10 port usb hub (this is not bus powered, it is externally powered) that looks ok and at a good price. Take a look: http://www.ebay.co.uk/itm/10-PORT-USB-HUB-2-0-High-Speed-UK-AC-Power-Adapter-/260726988676?pt=UK_Computing_LaptopAccess_RL&hash=item3cb48a1f84#ht_3193wt_905 That link takes you to one that has a UK power plug, if you are not in the UK then you will need to do some ebay searching to find one that will work with your electrical system. Your location is not included on your profile so i can not find one for your electrical system as i do not know what country you are in.

If your really looking for power, try this one: http://www.thinkgeek.com/computing/usb-gadgets/cef0/.
Although, if you're using it to transfer data I'm sure there's going to be some serious bottle-necking.
