ok so heres some numbers i got throughout the day...
first off my digi multimeter went for a swim in a puddle today so i had to find a replacement. i came up with an old analog multimeter and i dont really walk around with shunts in my pocket so i was stuck to 10amp unfused for most of the things i tried. reliable enough but not pin point accurate.
this is condensed
minimal set up = m2-atx, DG945GCLF2, Toshiba 80gb, usb touch screen, usb wireless keyboard
s5 9mA (m2-atx hardoff = false)
s3 120mA (usb=off; fans=off; wake from usb=false; hibernation countdown active)
s2 1.5 Amps (usb=off; fans=off; wake from usb=false; hibernation countdown active)
s1 1.7 Amps (usb=on; fans=on; wake from usb=true; hibernation countdown active)
s0 2.2 Amps (idle)
power was from a 12v 5amp ac/dc converter
all power states were forced via dumppo.exe
i used only what i needed to run windows because this is a good starting point for this board. ill do this again when i get another digital multimeter for better results.
i did add a wd 1tb hdd and dvd drive, tried to max out all four cores with video a converter, and all the usb stuff i could round up at work but nothing significant due to the gauge being analog.
but if u read this far u must want to know, each sata device drew about 250mA idle and 500mA while spinning up. the video converter i used maxed 2 cores and bounced around 70% for the other two and was just like the sata devices, drawing about 500mA more. i hijacked a few mice and keyboards and they did nothing but i cant find any high amperage usb devices... i cant even think of any...
