Hello List, n22e113 2¢ comment, which I like :-), got me wondering... what is the real power drawn by such a stripped down Mobo... Well, I hooked a scope on a small current transformer on the power supply line to my mobo, and this is what I get: http://i.imgur.com/dBN8PPT.jpg I was very surprised to see a current pulse drawn by the switching power supply right in the middle of the 120 volts.
The current pulse is about 3 amps peak and has a duration of 1.8 mSec. To simplify the power calculation, let's assume it is a square pulse, the power then would be roughly 3 amps * 120 v. rms * 1.8 msec/8 msec = 81 watts. The real value would be somewhat lower than that, and n22e113's estimate of 75 what-hour is in the ballpark... My kilowatt-hour here cost 7¢ (canadian) ! sorry I didn't want to rub it in :-) ! But yeah I still end up paying 46$. But then again, I can't resign myself to throw away performing good "old" hardware... jrb. ------------------------------------------------------------------------------ ------------------------------------------------------------------------ leaf-user mailing list: leaf-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/leaf-user Support Request -- http://leaf-project.org/
