- 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)
