Supplying Power to an ExpressCard USB 3.0 Adapter
I have a ExpressCard USB 3 adapter for my MacBook Pro 17. It is working fine, but it does not seem to be able to properly power my external HDD. The card has a power barrel connection on it, but I don't know what the power specifications are or what adapter I would need.
I see on the site that the unit usually comes with a "DC to USB Adapter Cable", but I did not get one with mine. Would a card like this directly deliver the power from the barrel connector to the USB port? Should I just be able to use standard 5v USB power by plugging into another one of my USB ports and converting to the right size of barrel connector?
The card I am using is a 1 Port Flush Mount ExpressCard SuperSpeed USB 3.0 Card Adapter with UASP Support.

The barrel connector on your card is to supply full power to the adapter's USB 3.0 port. Yes, you can use either a USB-to-DC plug cable (which is missing from your package) from any other USB port, or use an external AC-DC power adapter with matching barrel plug (likely something like 1.3mm/3mm plug). This question is about "use of equipment", so it should be closed as "off-topic".

@Ale..chenski, Thanks for the comment. I would classify this as a hardware question as mentioned in the FAQ. That being said, I do not see how a question about the usage of a computer hardware component would be off topic on Super User. I had to go read the FAQ again just to double check, and I don't see what your concern is. Is there a specific SE site that you think would be a better fit on?
