Whats the fastest pcie card that doesn't require a pcie power connector?

[bigshooter]

I'm going to use a Dell Optiplex 745 for a while, and need a video card. I currently have a 7900GT, but it requires a pcie power connector which the PS on teh Dell does not have. I also don't have a spare adapter plug to convert to pcie connector since the Dell PS is made for only components they supply.

Is a 7600GT my best bet?

Im pretty sure the x1650xt doesnt require an extra power connector and that should be a little faster than the 7600gt.
