I currently have a Dimension 9150
with a power supply of 375w and bought a new Radeon® X1900 GT 256MB PCI Express
recomemded by dell themselves. Come to find out now that the graphics card came in that it requires a 400w power supply while mine only has 375w. So I call dell and ask them if there is a mistake here and they come to tell me that the graphics card is not compatible with my Dimension 9150
. My question is is there a way that dell can upgrade or I can upgrade my power supply to 400w or more? Or am I going to have to get another graphics cards? If so could someone tell me some real good graphics cards in my specs? Please I need urgent assitance here.
