Do i need to have a source of power to use this? I see an on/off switch and a power port.

No, it powers up on it's own when connected to the USB cable that is provided with the package.

Hi, great question. You do not need an external power source such as an AC transformer that you plug into a 120 volt receptacle. After installing a SATA hard drive to your Sabrent enclosure, just connect the included cable from your Sabrent enclosure to any USB 2 or 3 port on your computer which will supply the necessary power to run your external hard drive and also send and receive data between your computer and external hard drive. Same as hooking up any of the USB 2 or USB 3 portable external hard drives on the market that uses your computer's USB 2 or 3 port to run and transfer data, and does not require an AC transformer to plug into the 120 volt power to run the external hard drives. Hope that helps answer your question.

No power source is required.use the included usb cable to connect the hard drive to the computer.

No, you don't need power for this great enclosure. This enclosure is very good can take my thick HDD too while many others cannot.I just connected only 1 USB 2.0 to my laptop without external power. I have to use 2 USB on my other enclosures. But if your computer cannot give enough power you can use 2 USB cable or connect external power.

Yes it needs power. Be sure and push the on/off butting to turn it on. There will be a small blue light show up for each USB you may have plugged in. I haven't had any problems and love it. Very fast with USB 3.

There is no on/off switch. To do so requires plugging it into or out of the outlet.

There is an AC adapter with the unit. That is the only way I can see to power it.

Yes you need a power outlet to plug the unit into for power. Hope this answers your question.

Yes. What you're doing is giving your outlet and on off switch. When it's turned on, the switch will light up green and the outlet will be powered.

No need power supply becaues it works off of the water pressure itself, so there is no electricity needed to run it. I used with my RO.

No, you do not need a separate power source. The cooling pad can be powered through a USB port on your computer. I choose to use a separate source to keep the USB port open for other devices.

No power is needed for this unit. You only need a water hose to hook up to. .

There is no ON/OFF switch so you will either have to (un)plug at the outlet or where the power adapter plugs into the box.

You don't need to. For the starter kit purpose there is a USB cable that will power the board from your computer when connected. However if you want to run the board and not have it connected to your computer than you will need a power supply.

A power supply is not needed. Just plug in the 2 usb plugs to your computer. Power comes from the usb connections. If you don't have 2 usb connectors, try Radio Shack or Best Buy to match the plug needed.

It draws power from the pc, so it doesn't need one. Had mine for almost a month and I'm really pleased with it.

Not needed, but if you have a lot to go through it does help. Also, you may happen to have a number of these power adapters laying around, you might already have one that works. Check that before buying one.

You just plug it into the computer via USB drive and set it up that way and you are ready to go. No other power source needed.

It can be powered either way. A power adapter is included in the box as well.
