Subman1, what symptoms did you get with having an underpowered PSU trying to run your gfx card? anything like the following:
1) very limited picture with trails left on the screen by the mouse
2) PC boots but the screen won't display - you can hear windows loading jungle and icons on taskbar 'poping'
I only ask as I'm addin an old ATI9600 to my GF's machine and that's pretty much what it does. I think that it's a PSU defficiency
