I have a 250watt psu and im wonderinf if i can throw in a 256 mg card something like a x800 or something ? WIll i be fine? I have a dvd player and 2 hard drives connected.
Is there any other information you can provide about the PSU? Brand? amps on the 12v?
The X800 series were pretty power hungry cards so I would have to say not to risk it, however more information on your current system could be rather helpful.
