Tools you will need to replace a power supply on a Dell Inspiron 5675

Before you begin, here are the tools you need:

  • Philips head screwdriver
  • Anti-static wrist strap

Make sure that these items are available before beginning the process of replacing your power supply unit.

It is important to note that the power supply unit on a Dell Inspiron 5675 is located at the back of the computer tower. To access it, you will need to remove the side panel of the tower. This can be done by unscrewing the screws on the back of the tower and sliding the panel off.

Additionally, when handling the power supply unit, be sure to avoid touching any of the components with your bare hands. This can cause damage to the unit and potentially harm you. Always use the anti-static wrist strap to ground yourself before handling any internal components of your computer.

How to safely disconnect all cables and components from your Dell Inspiron 5675 before replacing the power supply

Before starting, make sure to turn off your computer, unplug it from the wall, and remove the side panel from your computer case.

After disconnecting all cables and components from the power supply, you can proceed to remove the power supply itself. To do this, locate the screws or clips holding the power supply in place and remove them using the screwdriver. Gently pull the power supply out of the case, taking care not to damage any other components in the process.
