PSU rating was 350 i think but it never pulled that much.
I've got a plug through power meter - so i know the actual usage. Great toy! (and makes you turn stuff off at the wall all the time!)
My laptop with a totally flat battery is currently pulling 70W. It pulls
20w when its back at 100% battery.Part of the reason why i decided to get rid of all my full size machines and just switch to a laptop (well - 2 laptops now!). Less power used, less desk used and its virtually silent (I can only hear the HD spinning now)
