why do these PSU calculators give widely different watt estimates?

http://www.jscustompcs.com/power_supply/

http://www.3dcool.com/PWC.asp

http://www.casemodgod.com/psu_calculator.htm

Because they're all wrong? :) 

What does http://takaman.jp say? Even it's estimates are on the high
side, except the +3.3V draw, which should probably be tripled.

lol, it estimates my machine at a min of 294W, and I have a 300W PSU,
which is pretty good, but not the worlds best. I also haven't taken
into account my USB flash drive, 120mm fan instead of 80mm fan, and I
have done a FX5200 because they don't list FX550. So according to
those sites my PSU shouldn't be working. I also intend to add a better
sound card, which will be another 10W. It probably doesn't include my
onboard sound, or LAN either.

I'm a little worried about upgrading now, but it should be OK. They
obviously haven't considered CPU efficientcy either. They've
underestimated my hard disk by 5W too.
