GTX 250 if I remember correctly...as the GTX 260 requires 2 PCI-E connectors.

The point is how much 12v current can your psu supply. And the age of the psu.
PSU's have a roll off of amperage with age. At 450 watts you would be better off looking at a new psu first. Then a video card second.
There is a sticker on the side of your psu with it's current ratings.
