A USB wire will always have a way to transport power. This wire in the USB wire will not necessarily be used all the time but it will always be there

How do components get power?
A computer's power supply unit provides all needed voltages for the components of a computer that are internal. Externals either draw power from the USB bus (which in turn gets it's power from the aforementioned PSU or a Hub with a power supply) OR have their own internal power supply with a cable.
Can you Transfer files from a sata drive to ide drive?
Yes you can transfer files if your motherboard support both types of drives, if it has the connectors both for sata and pata (ide). If it supports only sata than you can do so by connecting your ide via usb port with a commercially available usb card and cable with its own power supply. Regards Rizwan Ghafoor
What meter has its own power supply?
ohmmeter has it's own power supply
What is an active USB hub?
An active USB hub is a USB hub which has its own power supply. It will come with a DC power adaptor to power it. The USB system in your computer is capable of providing electrical power to devices which are plugged into it. When a large number of devices, or some particularly power-hungry devices are plugged into the USB system, it is possible to overexert this system. An active USB hub shores up this this power reducing the likelyhood of problems. A passive USB hub does not. Additionally, USB devices will often not work properly with more than 12 feet of cable. An active USB hub (or active USB extension cable) can help to overcome this limitation.
Can you plug a non powered USB hub into a powered USB hub?
Yes. A USB port is supposed to provide a specific amount of power for USB devices. A non-powered hub does not provide the proper power, but is still useful for USB devices that provide their own power (some printers, some cameras), or those that need very little like thumb drives.
What is internal device?
That is a device that is inside the computer. An internal hard drive, for instance, is physically mounted inside the computer. It is not made to be used outside the computer, though there are kits to convert internal hard drives into external drives. There are external storage devices that are made to plug into a USB port. External devices either require their own power supply, or they get power from a USB socket. Internal devices get their power from the power supply which is already in the computer.
Do you need a powered USB hub?
The USB hub has its own power. Some devices use the power from the USB hub and some need more power then they can obtain from the hub. So to answer the original question -is a power hub better- There is no difference over is one better, one device just needs more power then the hub carries so it has to have its own power source.
How long can a USB cable be for a USB 1.1 device?
A USB cable (the 1.0, 1.1, 2.0 all have the same limit) is limited to 5m in length. You can make this longer using self-powered hubs (must supply their own power, usually by plugging into a wall outlet) as 'links' in a chain. You may have up to 6 hubs in a chain. This can give you up to 30m length.
Why do retailers now have the power in the supply chain?
To Control their own company
What is theTransformer rating in a power supply?
a power supply must deliver xxx watts to a load the transformer must match the load capabilities plus its own loss
