If I mount this in an external drive enclosure, do I need a separate power supply or will USB2 supply enough?

The drive power consumption is low, however; the external housing itself also would consume some power to create the connectivity. It would be best if you purchase an enclosure that uses a "Y" cable to connect the case to two(2) USB connector in your laptop.

It depends on the enclosure. Some enclosures are capable of powering the drive with just the USB.

No, it doesn't need a separate power supply, it can draw the power from USB port on a laptop. If you intent to connect it to an USB hub, make sure that the USB hub can provide sufficient power. Non/low powered USB hub will not work.

Well I've never mounted this type of drive into and external enclosure but I'm fairly certain (about 85%) that you'll need more power than what a USB 2.0 can supply. Then again, I could be wrong.

No, you do not need an external power supply for this drive. The 2.5" laptop drives are used extensively in passport type external USB only hard drives. Thought you must pay attention what enclosure you purchase. It has to have a power board inside that routes Sata3 to USB connection.

Your power supply needs to have enough power for every component in your system. If that is the case then each drive will have sufficient power. Each drive will still appear to be a separate drive unless you configure the drives as a raid; this cable simply provides power to the drive. You will also need a SATA cable to connect the drive to the controller.

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.

O Pharoah. It may be answered best by contacting Rosewill, like I contacted Thermaltake to ask if it would work for my external Tt HDD enclosure. Its specs state: Input Volt Range: 100-240V (Worldwide Compliant) / Output Voltage: DC 12V 2A (1.5A Compatible). The connector needs to fit also, as some power adapters' connectors do not. The description for the product says it is for a Seagate device. It may be quite generic fitting many devices. You could try it. Moses.

It's not a problem to power an external HD on this USB port. DVD? Sorry, not sure about that. Never tried.

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

Yes, provided you use your laptop near an AC outlet; the external drive has its own wall-wart power supply. If you want an external drive that's as portable as your laptop, look at the many small portable hard drives that are designed to draw power from the laptop's USB port -- or in some cases, two USB ports for full-speed performance.

I continuously run two 3GB external hard drives and occasionally plug in a third and never had any indication of a problem. Since this hub has an external power supply I doubt that you will have any problems. It is an exceptionally well-made hub.

You need to plug both USB ends. This way, your external HDD will draw more power than from a single USB 2.0 port.

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.

Just emailed Seagate to ask this exact question. Here was their response:The power supply specs are:Power Supply: 12-Volt 2-Amp OutputPower Supply Barrel: Outside 5.5mm Inside 2.5mmNote, this is really 2 Amps or more as the device will draw as much power as it needs, but must be 12-Volts only. So a 24 or 36 Watt adapter at 12 Volts with the right barrel size should work fine.

It seems clear that this unit does not come with a power supply, but seems to have a standard barrel connector to accept an optional power supply. To use small external (2.5") drives I need to have an external power supply. Can someone post a link to a power supply that will supply at least 2 amps and is compatible with this 4-port Sabrent hub?

mine has a power supply which i leave hooked up. are you talking about a different drive maybe?

Hey Bobbbo: I just plugged a 1 TB drive into the Micro 2. It gets its power from the USB, not external power and it's working fine. So you should be fine doing what you want. btw, I'm very happy with the unit too.

It depends on how many drives you will use simultaneously. If it is only one or even two, you will have no problem powering them. However if you will use more than two drives, you should consider buying an externally powered USB hub.

There's not enough power (amps) through USB, it needs to be a self powered drive but yes it can hook up to the USB.Also must be formatted in FAT32.

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.
