How to use external SATA?

[JoshSpence]

I'm looking at buying an Asus A8N32-SLI mobo and it has external SATA on the backplate, but it is only 1 port (data) I'm guessing so I'm wondering how this external drives gets power???

Thanks in advance,
Josh

Surely from the mains via the transformer/power supply built into the external caddy?
