    PSUs SLI ready question

    I am not exactly sure what SLI ready means on some power supplies. Well, it is quite obvious what it means of course , but does it also mean that if a power supply does not state that it is "SLI ready" you cannot have SLI or Crossfire graphics? For instance, is it possible to have two crossfire cards working with this supply: FSP700-80GLN? Any help will be much appreciated.

    As far as I'm aware, SLI ready power supplies can support ATI gfx cards aswell, its just a standard PCIE power connector. The "SLI Ready" bit afaik just means it can support 2 (or more) graphics cards and is certified by nvidia.

    AFAIK it is just marketing. I may be wrong though.

    Re: PSUs SLI ready question

    plenty enough power for the job, it won't have the connectors you need though so you'll want molex to PCIe adapters which should come with the card.

    SLi ready means it can SLi a certain number of cards dictated by the SLi Zone website I believe. That doesn't mean they have to be certified to do it though..

    Pretty much if it can do SLi it will do xfire of a similar card.

    If its quoted as "SLI Ready" it displays the NVIDIA logo, so I'd have thought certification would be necessary will look it up. Same goes for sli ready RAM

    Re: PSUs SLI ready question

    Sli certification and for that matter crossfire certification is marketing nothing more as long as a power supply has sufficient Amps on the 12v rails and number of PCIe connectors the is no reason it could not run multiple cards.

    Equally SLi certification is for a particular number and type of cards, so a power supply could be SLi certified for 2x 8600GT obviously this doesn't mean it can run SLi-ed GTX280s.

    Re: PSUs SLI ready question

    The support on these forums is awesome

    please excuse my ignorence, but is this what you are refering to when you say molex to PCIe adapter:
    www.scan.co.uk/Product.aspx?WebProductID=154684

    just want to make sure i understand what you are saying

    does someone have any experience with the reliability of such adapters? cheers!

    Re: PSUs SLI ready question

    ay that would be one and the reliabilty depends on how you load the power supply. All about how many amps youve got on the different rails

    Re: PSUs SLI ready question

    Yeah, mostly they are fine I think. I had some dodgy molex to SATA's before but win some lose some I guess. Most graphics cards come with them as standard though so feel free to use them

    Awesome... i guess if they are included with the gfx cards, then it is expected to be just fine Thanks a lot for all the info.

    As mike originally mentioned and strike quoted, however remember that they never say Which cards they are offically certified for there have been a couple of none too good psu's that got certified for low end/power nvidia cards, when better psu's of the same rated wattage were sli certified for higher power draw cards.

    Re: PSUs SLI ready question

    If something is 'SLI certified' then it may just be for 2 6800GT's. Doesnt mean it will take 2 x GTX280's.

    This SLI certified thing in SLI zone is nothing more than a gimmick.
    When the Corsair 520W first arrived it wasnt certified but had more than enough grunt to SLI.

    This is exactly why sites like SLI zone confuse people and should be taken with a pinch of salt.
