    Like the other anwser said: the adapter can provide 7W of power. The Fire standard (IEEE 1394) says that the max output is 30 V @ 1.5 amps so 45W. Seeing the size of your device and its complexity, there is a good chance it will require more than 7W of power and the provided adapter is 12V @ 1 amp so 12W (although an adapter is rarely used at full capacity). Unless they completely oversized their power adapter, you may need to plug it in.

    This adapter looks much more built to access FireWire external harddrives that are either self powered of portable and thus less power hungry.

    Let us know the results when you can!

  • My MOTU Ultralite does not work via FireWire bus power. I have an Iomega portable drive that doesn't work via TB to FW either. I have a SmartDisk drive that does work. It is a case by case basis it seems.

  • The description says it supplies up to 7W of power to bus power devices so as long as you sound card doesn't pull more than that you should be ok.
