    integrated video wattage.

    hi, as the title say, i have a an asrock board with integrated video. the sistem runs well centrafuse, with no problem whatsoever, but for the time being is still on my house for lack of a power supply. i was thinking to buy a m2, but then there is the question if there is enough juice for all the items. the question here is how much power needs the integrated video (nvidia6150 i think), considering that the motherboard normally needs arround 35 w to function (kb and mouse included). if i use the onboard will need more? and if so how much more? ( a separate video board will need anything from 30w up and come a little too close for m2 atx))

    I'm currently using a micro-ATX board with the nvidia 6100 chipset (http://www.biostar-usa.com/mbdetails...%20MICRO%20754) and a mobile Sempron processor (25W TDP). The system also has a 3.5" HDD and one desktop optical drive, Lilliput 629 screen, GPS, and PS2 keyboard and is temporarily powered by a 650W Antec PSU. At the wall it draws 61W, given that the power supply is probably less than 70% efficient at that low a draw you are looking at around 45W total for these components.

    so, if the mobo normally draws arround 35 w without using the onboard video, then if i use it will draw 45w, then the video only needs 10 w to ''perform its magic'' ?.
    is that what u say?

    Not sure what the motherboard itself draws, based on the numbers here the HDD and optical drive should take around 20W with the optical at idle. Not sure what the Lilliput draws but others have guessed 10W. The PSU I was using is 80Plus certified, so efficiency should be decent but very unlikely to be above 80% at that load. So if the other estimates are correct, that only leaves 25W or so going to the CPU/chipset/RAM.
