Does this require an external power source?

No external power source needed. Just simply plug in the 3.0 USB to the PC and you are set. :)

No, it will need to get power from USB cable. Meanwhile, it will also need to get signal and drawing through computer's support.

no this card does not... it is completely powered by its motherboard connection, no external connection needed, although i do recommend having at least a 500w power supply

Yes, it has a power port for an external power source, although I have not yet tried to use it.

Yes it needs power and it comes with the 5v power supply included that plugs into it. I was very satisfied wit the unit. I amplified the analog output using cheap computer speakers then pluging headphones into the jack on the computer speakers. The pictures and whats included in the box is shown out on the amazon site.

The unit does have an external power supply. Unit works well, no complaints here.

The device does require external power. It cannot run off of USB or eSATA power alone. So, yes, it does plug into an AC outlet if that is what you are referring to.

It has and requires an external power supply. I purchased this particular external drive because I needed an external drive that had its own power supply to get files off of an old laptop computer that only had USB 1.0 ports. USB 1.0 ports are old technology do not provide enough power to an external drive. It was by far the easiest way way to recover and save those files to use this self-powered external drive. There were other ways, but this was a simple solution for me. Moral of the story is that a separate power supply is not always a detriment.

Hi. With this device, you do not need any external power. The device brings it all included and takes what it needs directly from their computer. It works excellently. Regards. Vincent.

no it does not have a external power supply in the box. Although it does have an input jack for a 5 vdc power supply to be added. These are very common and easy to pick up at any electronics store

This device does not have an external power supply. It is charged through the USB port, which is a serious weakness in my opinion. That means I can use it on the go, but you can not permanently have it connected to an external drive and SD card, the battery will eventually drain. I really like this system for on the go, but I would also like a permanent set up where it does have external power, can connect to my 5tb external drive and put MicroSD cards in it to copy data to/from.

It is powered by the phone line, no external power supply. The old fashioned basic type!

Hello Dealzguy, This does need an external power amp. For the quality of audio it is entirely worth it! Michael @ Kraft Street Audio

No, it is powered by a cable which is included. It plugs into a standard outlet.

Yes, but only with external USB power source. I use a 5v dc out charging stick from GeekTek.

I guess there is a external power input, but it does not come with an adapter. so pretty much batteries only.
