No, the original poster's usage of an ammeter in series with the
computer is much more reliable.  150W is, as you might imagine, a
very general number.  The power supply is rated at that, meaning
that it can draw that much if necessary.  If you have no OD in a
cube, for example, it is certainly going to use less power.  But
your power supply is the same! (300W on my old cube)
Also, stating a wattage assumes a certain voltage, which is why the
original poster gave a load in amps and a voltage.  You get watts by
multiplying volts*amps.   .91*114, in this case. (note that this is
103.74, which is MUCH below the 300W that the cube's power supply
can draw if needed)
