Not sure, but you do have a lot extra's, so 750W could be underpowered just by a bit. Without all extra's i would say it's enough, but now ? There is a site somewhere you can calculate your systems powerneed, i'll try to find it for you.

September 5, 2011 3:45:20 AM < your looking at about 600w under load from the wall. Assuming 85% efficient PSU your looking at 510w, and thats running furmark which stresses the cards more than any game assuming your PSU can produce its rated power you will be fine.
2 reviews, 1 showing it can power 2 dual gpu gtx295's, very power hungry you should be fine.

And extreme.outervision is totally wrong ? Why does everybody reccomend this site then ? It's a a big difference 750 or 900 watts. Bit weird though the other convertor said 630. Pfffffffff, i don't know anymore.

You are looking at it the wrong way a HD6950 requires 2-6pin with 75w.
Not any PSU will do that are Crossfire certifed.
