The power supply will draw from the AC line only what it needs to supply the output.
Thanks I think that answers my ques.]]> http://www.dslreports.com/forum/remark,4823212 Fri, 25 Oct 2002 15:42:13 EDT Re: PC's power consumption http://www.dslreports.com/forum/remark,4821292 ScottMo : Interesting thread over in the Seti forum kinda relates to this.

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. ]]> http://www.dslreports.com/forum/remark,4821156 Fri, 25 Oct 2002 11:55:42 EDT Re: PC's power consumption http://www.dslreports.com/forum/remark,4820829 shearer : Didn't know there's a faq for this. Based on the chart, I'm using about 190W at most. 350 - 190 = 160W. Where does the extra 160 Watts go? I'm talking about this with the power bill in mind.]]> http://www.dslreports.com/forum/remark,4820829 Fri, 25 Oct 2002 11:09:48 EDT Re: PC's power consumption http://www.dslreports.com/forum/remark,4820035 CylonRed : No - it doesn't. Look at this and you can figure out how much wattage you are using: »Hardware Forum FAQ »How to calculate power supply wattage

Ignoring my desktop speakers, printers & other hware, does this mean that 350 Watts of electricity is being consumed when I'm using my PC?]]> http://www.dslreports.com/forum/remark,4819779 Fri, 25 Oct 2002 08:21:39 EDT
