An internal power supply is usually a battery. An external power supply means the electric current that you get by plugging your device into a wall outlet. If you do not have to plug it in, then it has its own power supply inside the actual device, in other words, it is internal. Aside from a battery, it could have photovoltaic cells to generate power, or other internal sources of power, anything other than an external source.

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.
What provides power to the internal components of the computer?
In the case of a desktop computer a power supply that in turn plugs into a household outlet provides power to the internal components of the computer. In the case of a laptop or tablet a battery provides power.
Will a psu only deliver what is needed?
Yes, the power supply will obviously only draw the power required for what ever load you place on the unit from your internal computer components. Each power supply has effeciency ratings some power will be lost.
Internal parts of PC power supply?
Generally, it contains AC-to-DC converter, surge protector, and cooling fan.
What type of computer is likely to use SO-DIMMs have an internal power supply and use a desktop processor socket?
A laptop.
Is the Gamecube's power supply internal or external?
The GameCube's power supply is internal. The whole system is very easy to transport.
Which option represents the main advantage of having an internal power supply in a computer?

What is a medical grade power supply?
Medical grade power supplies have additional components to isolate line voltage from internal voltage. Usually a 1 to 1 transformer with current and voltage cutoffs are used to transfer the energy from the mains to the internal circuits of the power supply. there are also additional opto isolators on the power supply that keep the external power from having any wired path to the internal side of the power supply.
Why does we use 250ohms with power supply for the instrument calibration?
We use the 250 ohms with the power supply because the internal resistance of a DC power supply is insufficient to develop a resistance.
What you mean by internal electrical power supply?
its when theres a power supply inside like a power pack so u can carry it around with u
What is the function of power supply in system unit?
The function of the power supply is to convert wall current to the correct current for the computer and distribute power to all the internal computer components.
How is an internal optical drive connected to the power supply?
the optical drive will connect to the power supply with a connector called molex connecter it is a 4 prong connector
What is an external power supply?
A power supply that is designed to be outside the case of the computer. Most laptop computers use an external power supply rather than an internal one to reduce size and weight while the laptop runs on battery power.
Why do you have ripples in your monitor?
The internal power supply could be failing, allowing 60 hz power variations to get through.
What is the piece of a computer responsible for providing electricity to all of the internal parts?
The power supply.
Why do computers require their own internal Power Supply?
Computers require their own internal power supply because the power required to power most newer computers, especially with high-end graphics cards, would require a bulky power supply which wouldn't be ideal in transporting computers or aesthetically. Also, with all of the other internal parts of a computer, some type of power interface would be necessary within the PC anyway, so why not just bundle it all together?
