AC adaptors, external power supplies, PSU.

Many computers, laptops and peripherals use an external power supply, often referred to as an AC adaptor. These essential parts provide power to the main device. This type of power supply is often used on devices that use batteries or have no internal power supply. 

An AC adaptor is made up of a central unit which draws power from an AC outlet (mains power socket). It then converts the power to DC that is used by the computer, laptop or peripheral and a second cord that plugs into the computer.

Each AC adaptor has a specific power rating, measured in volts or watts that it can handle and output to an electronic device. Because of the power rating and the type of plug on the end, an AC adaptor is not universal and can only be used with devices with the same requirements and connector.

Because each AC adaptor can have different connection for both the AC and DC connections it is important to check that the replacement AC adaptor has the correct connections. Below are samples of the most common AC and DC connections.

It is also essential to check the electrical rating of the adaptor, with each device requiring a specific power rating. Where possible it is best to purchase a replacement adaptor with the exact part number of the unit you are replacing, this will ensure compatibility with your computer, laptop or peripheral.
