			the 6950 should have the same 8 pin and 6 pin power plugs.  the 4XXX series only required the 1.  check your psu 
		
			Raistmer:
			
			HD4870 requires 2 6-pins plugs, look at photos I posted, there were 2 connectors.
I have 450W PSU

			Jason needed a new PSU when we got him the GTX 480. I don't mind chipping in for a bigger PSU at all. I am not rich, but I do care, and I've had a bunch of beer, so I can donate without worry.

Yeah, with throwing in my own funds as well, I was able to step up to the GTX 480, though originally only had planned on a GTX 470.  The PSU I had was a fairly decent 450Watt, but with all the other load on it I wasn't going to risk anything, So I borrowed a bit extra off the old lady to get a Seasonic gold series X-750.  
The PSU has  been running continuously, quietly & cool, ever since with no sign of stress at all, whereas the 450W supply I had is running a GTX 260 in the other room, and does appear to buckle under the strain from time to time.  
As a result of my good experiences with the X-750, when I need to buy PSUs again in the future I'll always look for the highest quality, most efficient unit I can find in whatever power rating I need + some headroom ...  I'll never buy an 'ordinary' PSU again.
