My computers I have on in the house are the LAST of my concern.. :-)
When you have to turn on the A/C in April...and don't get to turn it off till late November...I'm not really to concerned about the power consumption of my computers and all running 24/7.
Although I do tend to run most boxes headless...and turn off the monitors when not in use.
I figure if you've got the extra funds to put a computer together dedicated to MythTv....you shouldn't really be concerned about a little extra on the power bill...
:-)
Kinda like driving a Porsche, and worry about how much gas costs...

same current as the same size crt monitor. Function wise they are nearly
identical so you would expect the currents to be about the same too.
Where did you get those numbers from??? I have been in the repair business
for 40+ yrs and have measured the power consumption of a lot of equipment..
Really simple to do.. measure the current and multiply it by the supply
voltage = power. A typical 17-19" monito will consume between 100-140
watts.. max.. the surge current does not matter in the grand scheme of
things..
I agree with Rich here. I use amprobe equipment http://omnicontrols.com/lists/amprobere.html to measure draw on equipment (because we have to do these tests on equipment we manufacture), especially the high density machines (lots of drives, built in raid arrays etc).
I was initially surprised at how little they draw compared to the rating printed on the power supplys. (Deeper reading into the power supply specs would often reveal that they could not sustain their claimed rating for very long).
We even measure the power save mode on monitors to see if there was any real saving. Contrary to our suspicions (we tend to be skeptical) we found that monitors really do save a lot of power in powersave mode - not standby mode. Newer ones save much more than older ones.
Letting a monitor go to power save kills off just most of the load, and some models drop below 10 watts, (Christmas tree bulb country).
My personal opinion (no research) is that the wear and tear of power on/off does more damage to the equipment than letting it take care of itself and run 24/7.
Fans may not start if cold, but once started they very seldom stop. Will it start again when your myth box wakes up to record your show after it has been off for 24 hours?
