The H55M-USB3 has a native eSATA port.
In this review of H55/H57 motherboards (http://www.tomshardware.com/reviews/h55-h57-motherboard,2555-2.html (http://www.tomshardware.com/reviews/h55-h57-motherboard,2555-2.html)) it describes the eSATA port on the back I/O panel of the H55M-USB3 as "powered" (compared to some other boards, which do have eSATA ports but are not described as 'powered').
This is a bit confusing to me. Can anyone please confirm whether the eSATA port is in fact bus-powered (and therefore that an additional power source is not necessary), or would an external SATA drive attached to the eSATA port still require a separate power source?
Thanks for any help.

I have checked all the documentation that I can find and nowhere does it state whether the socket is powered. Personally I think that you wouild need a seperate power source as well. I have a X58A-UD7 board and it comes supplied with a flying lead for the back panel ESATA connection but even that has a seperate power socket.

Thanks for your help Dark Mantis. I guess you're right about the need for a separate power source. (I'll be able to test it when I get the board!)
Thinking about it, it seems pointless having a native eSATA port that's unpowered - better to install Gigabyte's PCI eSATA bracket, since at least then you can connect it internally to the PSU, whereas an unpowered eSATA port doesn't have that facility.
Thanks again.

Your welcome and please come back and let us know the answer for sure when you get your board.
