    that's for a 65w processor, and those values are a bit high anyway. i run a mATX intel board, and my manual has the same page in it. i run a 35w processor though, and if anything is overloaded on my m2 it's the 5v usb line.

    also, these intel boards have a lot of safety trips built into them. theyre not configurable or anything, but say you put too many usb devices on it, the board will refuse to boot until you remove the devices and reset the cmos.

    good eye on watching out for each actual rail though, just dont let that table confuse you. if you have a 45w chip, and the mainboard eats maybe 35w, youll have enough for a harddrive and a cdrom because youll rarely hit peak draw.. you dont game while encoding videos while burning cd's.... power all your usb devices with a seperate 5v regulated supply and you should have a very solid setup.

    ok then I would go for that motherboard :-)
    By the way is wattage calculation for AC same as DC? like watt=A*V ? if so, I just measured the amps that my dell pc is using at home. voltage was 230.6 and it was using 0.24 amps.... so it is even less than 100watts! it has normal big hard drive on it and it was playing DVD when I measured it...
    There is nothing impossible in the world :-)

    not too surprising, a majority of mid-level pc's out there dont pull more then 200w, even though most people think they need 400w power supplies.

    but yeah, without getting techinical about everything you can basically think of VA the same as Watts. E x I = P (voltsXamps=watts) and its the same a/c or d/c.

    there is actually a differene between VA and Watts, has to do with true RMS i think but it wont be any different between the two in our applications. i dont even know specifically anymore how it goes, im just an electrician it doesnt mean im that great at my job

    I understand peak and everything but on power on, the videocard/chipset also uses much less power. I have found peak system consumption to be when running IntelBurnTest and some graphics utility (don't remember the name but I use it for heat generation and stability testing in systems), not on power on, I've used 15-20 more watts here than getting a peak reading from power on. Of course, I also get 150w more with this than power on with my desktop system also (which fits a ton of hardware into a 380w psu - 325w peak current draw from the outlet/115v itself). I use a clamp meter for the higher voltages/amperage and a couple multimeters for the lower. I find that a Kill-A-Watt matched up with the clamp on certain readings/power supplies but is way off on others. The Ideal-branded clamp has been pretty damn accurate in my testing. I'll be glad once platter drives go away completely as they are noisy and power hogs in general - it will be nice to not have to figure them into any type of equation in any way. Intel does SSD properly with very low power consumption.

    I have the CPU voltage set with RMClock which only lets me go to the minimum VID, the same voltage used at 6x. I'm not losing anything by running the processor at its minimum VID for both idle and load. I really wish my motherboard allowed undervolting though - my Q9550 runs at 3.8Ghz at 1.08v in another system (lowest undervolt it will allow which is 0.1v under VID). Building an efficient system is useful both at home and in the car.

    Voltage rails are correct as they need planning but for me it's a non-issue as I must have most of my USB devices away from the PC and use a powered HUB for the job. This isn't to say people won't want to plug it all into the 4, 6, or even 12 ports available on some motherboards.
