Replacing the ACDC Power Supply

WARNING: The AC/DC power supply PCB remains powered up whenever the system is plugged in, whether or not the system has been turned on. Use extreme caution when troubleshooting the system with the front bezel removed.

  • Don't work alone. In the event of an electrical shock it is important to have another individual present who can provide assistance.
  • Keep one hand in your pocket when working on any iMac G5 (iSight) system that is plugged in. This will help ensure that your body does not provide a path to ground in the event that you accidentally make contact with the line voltage.
  • Don't wear jewelry, watches, necklaces, or other metallic articles that could present a risk if they accidentally make contact with the power supply circuitry.

1. Reconnect the power supply cables.

2. Tuck the cables under the DC/DC power supply/inverter and the metal chassis as shown.
