Apple Power Mac G4 Cube External Power Supply Pinout Needed

There are 4 pins in a trapezoid arrangement. The two that are farthest apart go to case ground. The other two do not. What are they? Both +28V? One +28V, one -28V? One +14V and one -14V? (The unit is rated at 28VDC out). If you can help, please make sure to tell me, looking at the plug, which pin has what voltage. Thanks.

Any power supply with the same pins will do. Just choose a good brand and with same rating or better higher(400 watts or more).

SOURCE: Power supply for Targus 4 hub usb 2

Most USB hubs do not need an external power supply, except when a connected USB device draws more power than the computer/laptop USB port can supply. In this case an external power supply will need to be connected to the USB hub.
Normally this would be a 5 volt power supply, but make sure the polarity on the connector matches the power connector on the hub, check the label on the hub, sometimes it states to power requirements of the hub as well as the polarity on the connector. Normally the pin on the hub's power connector is positive (ie. +5V)

Sounds like it's not grounding properly. Safest thing to do would be to replace the power supply. Hope this helps.

Resoring my g4 cube model #m7886 to factory


Get a copy of Tiger OS10.4 on DVD. The latest system, Leopard (OS10.5) is a bit too heavy for a cube. You can either purchase from Apple or "borrow" a copy from someone. Apple system software can be installed on more than one machine. Put in the DVD and restart holding down the otion key so the computer starts from DVD and follow the instructions for a "clean install" erasing the hard drive.
