Size and weight detail
Size and weight detail	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.	Apple's 3.4 × 16.3 × 15.6 inch and 14 lb reference dimensions; metric fields are rounded conversions
Power supply
Power supply	450 W on dual 2/2.3 GHz; 600 W on dual 2.7 GHz, as stated by the maker.	Apple's support sheet states 210 W maximum, 100–240 V AC at 50–60 Hz; a Low End Mac profile lists a 200 W supply, so the figures may describe different measurements
Materials
Materials	Aluminium enclosure.	–
In the box
In the box	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.	Original System Software 7.1.2 with PowerPC Enabler 1.0. Apple dates the 6100/60 introduction to 14 March 1994; its 66 MHz replacement was a separate January 1995 model
