The power supply in an iMac computer is responsible for providing a safe and consistent power source to the computer. The power supply regulates the voltage and amperage that is supplied to the computer, which helps to protect the computer from power surges and other power-related issues. The power supply also provides power to the computer's components, including the processor, memory, and storage. While the power supply is a vital part of an iMac computer, it is not the only component that is responsible for the computer's power needs. The processor, memory, and storage also play a role in the power needs of an iMac computer. The processor is responsible for processing information and data, and the memory stores data and information. The storage holds data and information that is not being used by the processor or memory.

 

There are two main types of power supplies for iMacs; an AC adapter and a DC Inverter. The AC adapter is the simplest to use and is the most common. The DC Inverter is more expensive but is more versatile.

To change the power supply in the iMac, first shut down the computer and unplug the power cord. Next, open the back of the computer. Locate the power supply and disconnect the power cable from it. Finally, remove the power supply from the computer.


As of 2019, Apple no longer sells the DC Inverter.

Although the process of changing the power supply in the iMac is relatively simple, there are a few things to keep in mind. First, be sure to shut down the computer before unplugging the power cord. Second, be careful when disconnecting the power cable from the power supply. Finally, make sure to remove the power supply from the computer before tampering with any of the other components.

With these simple tips, changing the power supply in the iMac should be a breeze.
