Dell D830 Powered USB 2.0 port

The Dell D830 comes equipped with one powered USB port at the rear. The powered USB port is compatible with USB 2.0 connector. When used with a powered USB connector that looks like a bloated RJ45, powered USB port can supply 5V (beige), 12V (blue), or 24V (red). They are color-coded and connectors are keyed to distinguish between them.




I had a close look at the powered USB port at the rear of my Dell D830. It did not look like a 24V keyed connector or a 12V one. So I guess it must be the 5V type that can presumably supply up to 6 Amps per connector.

What accessories can I buy to take advantage of this powered USB port? I could not find anything in the web or in the shop. Many shops don't even know there is such "powered USB" standard!

 

The powered USB port on the back of a D830 is of a proprietary standard. AFAIK, the only thing you can use with it is Dell's own D-Series external optical drive module.

You can add a secondary hard drive in there as well.

 

I am thinking of a USB hub powered by the powered USB port with high current supply. If the one on the D830 is proprietary then it is not very useful then. :-(
