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.	Original UK and US brochures publish 152 × 330 × 419 mm and 11.3 kg, varying with installed devices
Power supply
Power supply	450 W on dual 2/2.3 GHz; 600 W on dual 2.7 GHz, as stated by the maker.	Automatically configured 100–240 V AC, 50–60 Hz. Service Source gives 167 W maximum continuous and 230 W peak input, excluding the monitor, with 112 W continuous DC output. Original brochures instead list 325 W maximum, while exact English support lists 230 W; the differing conditions remain qualified.

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 brochures include System 7 software, setup/learning/reference documentation and limited warranty. Exact support lists original System 7.1.2 with PowerPC Enabler 1.0 and introduction on 14 March 1994. Contemporary May and July 1994 reviews test retail-priced 7100/66AV configurations; release year 1994 retained, with first-sale month unresolved.
