I wouldn't worry too much. Your 260 is probably already taking up 2 slots and using PCI-E. As far as power, the gtx 260 may even have a bigger draw. And you can buy a dual 4-pin to 8-pin adapter for less than 10 bucks.
If you are already tight, though length wise, check the dimensions of the new card and make sure it will fit.
