Psu good enough for SLI?

Hey guys, this is my first post and I joined specifically to ask this question. Would the psu that I have already http://www.newegg.com/Product/Product.aspx?Item=N82E16817171014, would I be able to run two 9800gtxs in SLI? I was told that it did not have the right power connectors but I wanted a second opinion.

  1. I reckon you will be ok, you may have to use molex to 6 pin adapters but thats not a major issue. Power and wattage should be OK.
  2. I don't think you'll have enough power, only 18A per 12V rail.

    My friend is running a pair of 8800GT's on one of those and has been for the last year or so with zero problems.

    According to that chart, 9800GTX is 10A at load. My math says that 2x10 > 18, and that's not taking drives into account.
  5. hopefully he could put one on one rail and the other on the other rail (it has 2x18A rails)
  6. IMO it would just be safer if he upgraded his PSU too. CM isn't a good brand for PSUs

    What about the second rail? Couldnt I use that?
  9. Evga only recommends 30a total on the 12v rails and from what I see I have 36(2x18) so i'm thinking I should be alright...

    The rails are generally not additive.

    No. The PCIe and Molex should all be on one rail if there are only 2.
  12. How exactly can I find out if they are seperate? I shut off the power and checked inside but I couldnt really figure anything out from it.
