Size and weight detail
Size and weight detail	Exact maker reference weight 19.1 kg varies with configuration and manufacturing process; height 43.2, width 22.7, depth 46.8 cm. These published dimensions differ slightly from earlier G4 sheets and are retained.	Original Apple Service Source lists 360 × 196 × 396 mm and 11.5 kg, varying by installed devices. The US brochure's 30.6 cm height conflicts with its own 14.25-inch figure; the UK brochure and Service Source give 36 cm. Apple's support sheet lists 14 × 7.7 × 15.75 inches and 25.3 lb; metric headline dimensions use the original service document.
Power supply
Power supply	100–125 V AC or 200–240 V AC, 50–60 Hz. Maximum current 6.5 A at low voltage or 7.5 A at high voltage; maker publishes no maximum wattage here.	Automatically configured 100–240 V AC, 50–60 Hz; Service Source distinguishes 298 W maximum continuous and 453 W peak AC input, excluding the monitor, from 200 W continuous DC output. Brochures and support list 200 W maximum without that distinction.
In the box
In the box	Mac OS X 10.2 Jaguar as default startup system, plus bootable Mac OS 9.2.2; iMovie, iPhoto, iTunes and iDVD for SuperDrive. Maker August 13 release says dual 867/1 GHz available that week, so first sale uses August month precision. Actual dual-1.25 GHz shipping confirmed 18 September. January 2003 FireWire 800 models and June 2003 reissue are separate generations.	Original System Software 7.1.2 with PowerPC Enabler 1.0, setup and reference documentation and limited warranty. Apple records introduction on 14 March 1994; April 1994 Apple Directions states the exact model is available in large quantities worldwide, establishing sale in 1994 without resolving the first-sale month.
