I would buy another power supply but if the 460 can handle it, I should be fine?
I did ask if the 6850 used 460 watts and she said yes. So it does look like the system should handle the 6950.
My god are computers complicated.

Measured power consumption Radeon HD 6950
System in IDLE = 174W
System Wattage with GPU in FULL Stress = 312W
Difference (GPU load) = 138W
Add average IDLE wattage ~ 20W
Subjective obtained GPU power consumption = ~ 158 Watts
The 460 watt PSU in the Dell system will be fine, even more so because Dell certifies it for 6870s already. The power requirements are similar.
