Besides a graphic system that will cost more than $2000 by itself, these new machines will also include a more capable power supply with an output of at least 850 watts on the lower end and 1000 watts on the high end. Interestingly, these power supplies are not just expensive at around $400 per unit, they apparently are also nearing the limits of the power capability in some residential buildings, as some users have reported to us. Especially users who live in older houses may want to check, if their current power system supports a 1000 watt computer system.
