I know its a kind of weird question but i have a rig that has the same ATX 400watt psu as a friend now the one i have is running a x1650xt and he asked me what sort of power its using,well i dont know but he wants to upgrade his graphics from a x800 series card and asked me the question to try and work out if he could run a 1950GT on his.

So the question is how much differance is there between the two cardspower wise ?

Yes i know its not the most scientific /best way about it but i said i would try to find out so here i am
