All they do is estimate the watts, not the amps, a serious drawback
because so many PSUs are now optimized for either +5V power or +12V
power, i.e., a 300W PSU made for +5.0V CPU power may have a combined
+5.0V and +3.3V power capacity of 245W, but that capacity may be just
115W for a 300W PSU optimized for +12V CPU power, and even a 550W PSU
may have only 150W combined +3.3V and +5.0V power. It's too bad that
Takaman's power estimator is no longer available.

Also in the case of dual rail +12V PSUs it would be nice to know the
amp draw for each +12V rail because these rails have caused problems
for some people.
