    ATI 3870x2

    Looking into buying one of these. Probably the MSI 3870 x2 version as it is HDCP ready.

    On investigation it would appear that these cards have both a 6 pin and a 8 pin power sockets on them. Does this mean that you have to connect power to both sockets OR is it a choice of either or dependent upon your PSU's available connections.

    Re: ATI 3870x2

    Oh! I see.
    I have 2x 6pin PCIe and 1x 8pin power plugs on my PSU. The 8pin I was reserving for use with my new MoBo when I get it as it requires an 8pin ATX supply, so that basically will mean that the two PCIe power plugs I have will both be required therefore leaving no power supply for the second GPU.

    I won't swear by this, but I think you'll find that the motherboard 8-pin socket won't fit in the one for the graphics card.

    For reference there are shorter X2s around which will take 2x6pins.

    You could be right! Either way I've decided to buy a new PSU so that should solve all the problems.
    Probably will be this one:- TAGAN 900W

    I believe so. The only reason I was looking at the MSI one was because it said it was HDCP ready which once I've sorted the rest of the computer stuff will most likely be my next challenge.

    Re: ATI 3870x2

    All 3870 X2s should all be HDCP ready so that should not be the deciding factor.

    Just checked Sapphires specs on their website and it says they are HDCP compatible
    ATI RADEONâ„¢ HD3870 X2

    SO personally I would look at the other manufacturers especially as they are quite a bit cheaper

    Thanks Webby. To be honest I was purely going off the information given on the Scan website.

    Re: ATI 3870x2

    The shorter ones with two 6 pin connectors come pre overclocked too, but they still cant be bought anywhere!

    GeCube and Powercolor make them.
