More about 6950 crossfire enough
  1. 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.
  2. Damn 900W well guess i should be shopping for a new PSU then....sigh!!!!
    i tried a convertor before also it said 630 Something
    well its better not to take chances with this

    http://www.legitreviews.com/article/1488/18/ < 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 will......so assuming your PSU can produce its rated power you will be fine. http://www.guru3d.com/article/in-win-commander-750w-psu-review-test/6

    2 reviews, 1 showing it can power 2 dual gpu gtx295's, very power hungry cards.....so you should be fine.
  4. 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.
  5. Sorry about the Delay Had Exam's...well then I Ran a lot of Benches and it seems to Running fine on my 750W YAY!!!
    @iam2thecrowe you were spot on, thanks buddy!!!

    @robojordy

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