Does this unit require power (using the provided power adapter) when using it with a 2.5" hard drive?

Yes. Mine has been working for 4 months with no problems, but the power is necessary.

It works without power supply when attached devices have little power consumption but peripherals such as an external hard drive that draws power from the port requires the added boost of the external power supply.

Yes, I have found that it does not work with larger disks without the AC power.

Depending on the drive.. Some smaller (2.5", 1.8", etc) drives enclosures require no additional power and if they are capable of using a single (or sometimes dual) USB ports for operation, you will have no trouble using them with this hub. However, larger drives (3.5") enclosures must be plugged in to external power source (they usually come with power adapters). For those you will not be able to operate them with this hub only, without external power source.

I don't quite know... You should probably ask the cooler master people via email. Personally, running this without the power adapter doesn't work for me.... But I haven't even tried. Though this is a good question I'm interested in finding out about... If I find an answer, I will post it here.

Absolutely yes. There is an A/C power cord included in the packaging. If I remember correctly an additional 12v of power. Which should be sufficient enough for external 2.5 inch has.

Supports ALL 2.5" Hard Drives (7mm, 9.5mm, 12.5mm, SSD)I put a 2.5" Laptop Hard Drive in mine and it works fine, however...Be advised this does not have a Power Supply.I had to plug in two USB Cables, one for the drive and one to power it.The unit comes with this two plug cable.

No. It's powered by the pcie connection. It has an optional power supply adapter, but its not necessary.

If power adaptor is an issue you can get by without using it. It takes the computer's internal 4 pin molex connector which is a day saver.

Mine did, external drives normally need an external power source. This was for an older WD MyDrive 500gb.

No. It does not come with a 2.5 adapter. I wish it did. I actually had to use a 2.5" drive when the 3.5" WD Green that I originally installed died. I was able to connect the 2.5" drive but there was no way to secure it in position. I had to use tape temporarily.

i plug in a couple of external drives w/out power source all the time. works just fine. don't know if it'll power more than 2.

Yes. Powering the harddrive may be an issue if the harddrive requires power from a separate power plug (ie. other than the data connector plug).

Yea same thing with me I don't think it gets the recommended power from the usb ports...u should try the sabrent adapter...it comes with a dedicated power cable to plug into the wall and the adapters for 2.5 and 3.5 sata/ide hard drives.

Yes, there is a power adapter with the unit. I did not try to power my Pi with it though.

Is the power adapter necessary for this drive or will it run off he computer battery if needed?
