Conclusion:
It was slightly surprising that power usage for home systems were well
below the 100 watt level, but note that all configurations are of a
minimalist nature. The newer Coppermine computers actually use less
juice than the older P2/Celeron configurations. With 3 Hard Drives, 4
RAM strips, 2 CD-ROM�s, and six add-in cards, I could easily believe
that peak power could exceed 150-200 watts. Of course, those crazy
overclockers out there with 10, 3 watt fans and 2, 50 watt peltier
coolers will experience higher usage too.
