This wireless card WORKS WITH the Power Mac G5 models which have two USB 2.0 Ports AND one Gigabit Ethernet Port (on back panel). ---------------------------------This wireless card WILL NOT WORK with Power Mac G5 (Late 2005 Dual 2.0/2.3 Ghz) and Power Mac G5 (Late 2005 Quad). These models have three USB 2.0 Ports AND two Gigabit Ethernet Ports (on back panel), and require a Different Wireless Card (and I don't have it). Regarding iMac G5 Compatibility: FYI. This wireless card works with all iMac G5 models that were made. It is the only wireless card made for the iMac G5. ----------------------------------------------------------------- This item is guaranteed to work in the above situations, or your money back (within 30 days of the sale).
