Can this be used WITHOUT the power supply attached? i.e. w/o power, does it work as a simple hub?

No, without the power connection it doesn't work at all. It goes dark and the items connected are not recognized. I am using it on a Windows 8.1 computer.

NO! It is a powered hub. Having said that, I love these puppies. I've got 5 total in use and highly recommend them. (See my earlier review.) on USB 3 items, they'll draw power from their own power supplies and the computer itself, you DON'T ever want to take a chance of burning out the USB on your puter or the device (Like hard-drives) due to a low power situation, EVER!The plugable 7 port hub is lighted to let you know when the device is properly connected and powered, on each port.

Yes,i connected mine,you just need one power connector with,6 pin on one end,8 pin on other end,i honestly can tell you that i have not tried running it without the power connector.

I don't think this hub is built to deliver that kind of power. All my external USB hard drives are separately plugged into the A/C. At minimum, your drive would probably have to be plugged into multiple USB ports.

I haven't tried either, but it should work. Since the hub takes up more space in a small area that I like, I don't use with my laptop.

The power supply plugs into any standard electrical outlet (110-115 V). I have not tried using the hub as a bus-powered device.

Hi Aaron, I just tried out, and NO, you can not use this without power adapter

No external power supply is needed. It is "plug & play". It gets power from the computer's ExpressCard/34 slot.

Yes. I have connected multiple external hard drives to this hub. It is a powered hub and will power drives that are not externally powered themselves (Drives which have only a USB connector and no DC adapter input).

Good question. I would have to say get one that has a power adapter included. Amazon has one: Esco-Lite 7-Port USB 3.0 Hub with ON OFF Switches and LEDs +5V 2A Power adapter This will cost more, but if under power it can be used WITHOUT a PC. I can not recommend using this with all ports active. I could not test that, because only 3 of the 7 worked. They are sending me another one, if I remember I will re-post if they all work.

It does require a direct connection since it does not require any software to run it. As far as I know, it will not work in a hub.

This hub isn't for doing that. It's for adding USB slots when your computer's USB slots are filled. I have USB lines from two external drives, a printer, a mouse, and a cooling pad hooked up to my hub. You'll still need to plug your external drives power adaptors into a suge surpressor.

Hi. The stand gets all its USB power from the computer. There's no separate power supply. However, that said, I've connected WD Passport Drives and an HTC Android phone to it and didn't have any problems with lack of power. Usually, unpowered hubs don't have enough *oomph* to keep an external drive going, but this one does very well.

My fan did not work coming out of the box so I never had a chance to use it with all 4 USB ports supporting devices. From reading other reviews, unless you have an external power source, it looks like the hub does not have enough power to support 4x power-hungry devices.

The hub has a 12 volt, 2 amp power supply. I assume the amp capacity is divided among the 4 ports. You'd need to find out what the current draw is of the external drive to be sure.

This item doesn't require any external power connectors; it only draws power from the PCI Express slot. Hope this helps.

No. It gets its power supply from the raspberry itself. No need for external power
