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.	Shared Service Source gives 85 × 415 × 399 mm and 6.4 kg, varying with installed devices. Japanese 6100/66 page gives 396 mm depth; April 1995 AppleFacts gives 86 × 411 × 396 mm and 6.3 kg. Different maker measurements remain qualified; shared service values retained for this AV record.
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. Exact English support lists 210 W maximum. Shared Service Source separately gives 132 W maximum continuous and 201 W peak AC input, excluding monitor power, with 86 W continuous DC output; conditions remain qualified.

Exact support lists original System 7.5 with PowerPC Enabler 1.1.1 and introduction on 3 January 1995. April 1995 AppleFacts lists the current 6100/66 with an Apple AV configuration, and Apple's TIL describes the AV-card upgrade. Release year 1995 retained; first-sale month unresolved. Japanese standard bundles include KanjiTalk 7.5 CD-ROM, manuals and warranty.
