Apple and Intel weren't kidding about "low power"

without nomen: i can't remember a time i didn't know of the word sans... oh. and its french, not nearly so pompous.

The power supply must be able to provide power to peripheral equipment via USB and FireWire. That's accounts for some of the headroom up to 120W. Apple has probably factored in future speedbumps in this estimate also...

What is going on? Is everyone in the office using "sans" as if it is a viable word in everyday language? Do you know how obtuse it makes you sound? You would be better off sans it. I say that sans the word "sans" the world would be a better place. In fact, sans "sans" this post would be sans meaning. Get my drift or are you sans any clue to where I am going? Oh how Latin makes those sans a thing to say sound like they have something to say. But I can hear that you can't just use sans where "without" would normally be, but are they sans sense.

#11: Are you seriously trying to compare an iMac with a Core Duo to an Athlon XP and a G3 300?

The Quad 2.5 G5 has a 1.0 KW power supply!

Can't wait for low performance per watt powermacs

Pentium 4 with 300-400 Watt power consumption? Not really... if this would be just due to the proccesor, that'd be a heater at best! The nominal maximum value of a AT(X) computer power supply is usually far from the actual value the system draws.

@TUAW makers: please be fair and don't overdo it.

For the records: my Powermac G3 300Mhz draws as much as my AMD XP1600 machine, ca. 65 Watts (after booting). Get a power meter from the DIY store and gain some insight. They aren't expensive these days...

Think about the print advert:
'Did you know the new iMac uses less power than a standard light bulb, Another reason not to care about windows'
SEE THE PUN, THE OS AND THE GLA... nevemind...

Very impressive, it's like a laptop on a stick! ;-)

Many are noting the difference between the max of 120 and the actual of 95. Note that the machine must also be able to provide power via FW/USB/DVI to external hard drives, scanners, iPods, speakers, external monitors, etc. I'm sure that overhead of 25 watts was carefully chosen. I do not believe this is a case of Apple exceeding any specs.

I agree with #4 (Andrew). Apple seems to be a company that would help the enviorment. And that is a + in my mind.
