Background and Identification

The Apple PowerMac G5 is a desktop computer first produced in 2003 by the Apple Corporation. This guide will review the repair process of an Apple PowerMac G5 model number A1177 EMC 2023 from 2005, unless other wise noted (read "I only have one model at the moment"). The model number is located on the underside of the computer. The model can also be determined from the desktop specifications when the computer is operational. This particular model contains a 2.3 GHz dual core processor, up to 16 GB RAM, up to at least 1TB hard drive per bay (2 hard drive bays total), and a single super-multi DVD drive in the front bay of the computer. The guide will underline this particular model, but Please feel to edit if you have a different model.


It is possible to upgrade a few components on the desktop.

  • Memory: The PowerMac comes standard with 1GB of memory although it is possible to install more to increase performance. "Omega" G5's from 2003 came standard with 4 GB of RAM. The maximum ranges from 4GB to 8GB depending on the specific model.
  • Hard drive: It is possible to upgrade the hard drive to up to 1TB (maybe more, depends on what the firmware allows) depending on the model to increase capacity. It is also possible to install an additional hard drive into the computer.
  • The optical CD/DVD drive: The disc drive can upgrade from the standard CD/DVD drive to a super-multi drive to increase performance and usability.
  • Video card: It is also possible to upgrade the video card but be sure to check compatibility with the graphics card and Apple desktops.
