There is a DC input port - does the unit require power? If not, what is the dc port used for and where can i get the dc power source?

Mine worked with power from HDMI port. I don't believe external power is required.

It doesn't require power, so long as your input device provides power. Which assuming it's a TV, 99% of them do, the DC power unit can be found pretty much anywhere, just make sure you get the right wattage/voltage.

It is plug and play. You don't need a power supply. Plug it in. And it should set up.

The box itself runs on DC. You get a wall wart with it that uses your outlet AC to feed the box. So the power requirement you are stating is on the wall wart--Is that what you mean?

It's supposed to need two USB ports to power it.source: http://reviewstash.com/viewtopic.php?id=1046

This unit requires a power source. I would not purchase it. I have found better that would work for your application.

the unit is powered by your HDMI devices and should work without a DC input.

If you switch the input polarity the unit will not function at all. It has a diode. The unit will not light up. It will not turn on. It will not work. DC polarity must be connected as shown on diagram. Can you tell me why you wanted to change there polarity?

No external power supply on this unit. Just a regular 2 prong plug straight from the unit.

Mine only has one USB port. Power and data are through a single USB cable. Sounds like you would be better off with a unit that comes with an external power supply. More of an opinion than a proven fact. Good luck.

It has to get it from the USB because there is no other power supply directly going into it, why is this question even being asked?

This unit is DC powered, so I'm assuming you are referring to a DC powered system where you are wiring directly to a 12V DC power source... try it!

I had to provide my own power source. Power is not wired to these points on the circuit board. Start with a simple continuity test using an ohm meter.

Austin,I used this unit integrated into an alarm unit for a friend, but as I remember it is has a dc power jack on it for the 12 volt output. It also includes a dc power cable with female connectors on each end. One end plugs into the power jack, the other end will plug into whatever you to operate. You will need a matching male dc power plug, which can be purchased at Radio Shack etc. Hope this helps,Jack

Apparently it is powered exclusively from the USB port itself, not too certain on wattage however. There is a s/pdif out and in, and a 3.5mm line in (I use a red/white composite cable converter to play any console games). I believe the software that runs it is strictly PC, but I have no certainty that it will function in this manner.

Power was provided by the outlet and we stream audio to the stereo direct, no port needed for that. I hope this helps.

Hi Jon,The unit is USB powered. You dont need a seperate power unit. The USB cable is included.

It seems clear that this unit does not come with a power supply, but seems to have a standard barrel connector to accept an optional power supply. To use small external (2.5") drives I need to have an external power supply. Can someone post a link to a power supply that will supply at least 2 amps and is compatible with this 4-port Sabrent hub?
