Is an AC adapter necessary?

AC adapters help reduce the size of a laptop computer by alleviating the need for a standard sized power supply. If necessary, a universal AC adapter can be used, which is designed to work with many devices, having multiple types and sizes of plugs for connectivity to those devices.

Do AC power cords make a difference?

Too much is often made of the impact of cable attributes upon video and audio quality, but it’s fair to say that any cable in the signal chain, carrying signals, has at least the potential to have an impact upon the quality of your system’s audio or video output.

Can you use any AC power cord?

As long as the voltage is the same on the adapter and on the device (also, I have 9V DC and 9V AC adapters, do not mix these up) and be sure the current required is less than the amount that the adapter can source otherwise you risk overloading the power supply.

What is the difference between power supply and adapter?

A power supply for electronic devices. Also called an “AC adapter” or “charger,” power adapters plug into a wall outlet and convert AC to a single DC voltage. Computers use multiple DC voltages, and the power adapter is the external part of the power supply for a laptop.

Are expensive power cables worth it?

An expensive cable might sound worse on your system than cheap cable. Or it might sound better. The important thing to remember is that even if it does sound better, it’s such a minuscule improvement that pretty much anything else you can do will have a greater effect on the sound.

Are all AC power cables the same?

In the US, that’s almost always 120V AC. The number on the power cable determines the maximum safe voltage for that power cable. Therefore, in the US, any cable rated to 120V or higher will work fine. Now, you do have to worry about the current printed on the cable.

Do all PCS use the same power cord?

Power cords for desktop computers are the same. There are regional differences due to the configuration of the plugs around the world, but that is it. If you have one that works in your area of the world on one desktop, it can be freely moved to any other desktop.
