Re: PC's power consumption
The 160 watts doesn't "disappear." 350 watts is the rated output of the supply- your machine can use up to that amount before overloading it. The power supply will draw from the AC line only what it needs to supply the output.
Power supplies aren't 100% efficient in converting AC to DC, so if you're pulling 190 watts out, there might be 225 or 250 watts of AC going in (the difference between input and output is dissipated as heat).
I have several machines running Team Helix projects 24/7. Early this year, I estimated that each machine consumes roughly $5/month of electricity. (This estimate was during the heating season, before the heat generated by several machines started having a HUGE impact on my electric bill due to additional air conditioning required.) This works out to a little under 100 watts. |
