I've never seen a mobo that could handle that. :-) Must have the cooling system from hell in there! > If there were an easy way to measure it I would :-) If you have a clamp-style AC ammeter, you can get a widget that you plug into your outlet and your system plugs into the widget. The widget splits the hot line out separately. You put your ammeter around that leg and measure the current. You can compute your usage using Ohm's law, e.g. if you measure 2A at 120V, that's 240 VA. If you want it in watts, your average computer has a power factor of about .8, so that'd be 240 times .8 or 192 watts (or so). Just an idea. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@xxxxxxxxxxxxxx - - AIM/Skype: therps2 ICQ: 226437340 Yahoo: origrps2 - - - - "The bogosity meter just pegged." - ---------------------------------------------------------------------- _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
