Size and weight detail
Size and weight detail	43.2 cm height, 22.6 cm width, 46.7 cm depth and 13.6 kg reference weight; weight varies with configuration.	The exact maker sheet labels height as 47.5 cm, width 20.6 cm and depth 51.1 cm. Earlier G5 sheets label height/depth in the opposite order; main dimensions are omitted because those published axes conflict. Maker reference weight is 20.2 kg and varies with configuration.
Power supply
Power supply	Maximum continuous power 220 W.	450 W on dual 2/2.3 GHz; 600 W on dual 2.7 GHz, as stated by the maker.
Materials
Materials	–	Aluminium enclosure.
In the box
In the box	Mac OS 9, QuickTime and iMovie 2. Apple confirms all three factory configurations immediately available on 19 July 2000. Later review software updates are not launch firmware.	Mac OS X Tiger and iLife ’05. Apple’s 27 April 2005 launch says these models are available “this week”; first sale is kept at April precision rather than treating the announcement as a confirmed delivery day. The older single 1.8 GHz model retained in the launch range is represented separately as Late 2004.
