Removing and Replacing the Power Supply Unit

To Remove the Power Supply

Note It is recommended that for many operations on the inside of the PC, you remove the power supply unit without disconnecting the power cables to allow easy access to internal components. Where this is necessary, it is indicated as such in the following pages.

If you need to replace your existing power supply with a new one, refer also to page 67.

1Once you have removed the main cover, lay the PC on its side.

2Release the power supply cables from the cable clamp under the floppy drive bay.

3Press down the retaining clip at the top of the power supply unit, and holding the unit carefully, rotate it upwards.

4Push the second retaining clip outwards and lift the power supply unit out of the PC and lay it by the underside of the PC, not beside the front panel. If you are not replacing the power supply, you do not need to remove its connections to internal devices or the system board.
