    While I think It will work, you are cutting it really close. For Crossfire/SLI set ups it's good to have a PSU 700w+

    Agreed, personally I would strongly consider upgrading to a 750W or higher.

    Gtx 660ti sli required 40A and seasonic have 48A but I'm more concern about full load consumpion I think it's about 550w so I don't have much psu power?

    As I said, it should work. However, it will be close, especially if you plan to OC. Luckily, you have a quality PSU in which should be up to the task.

    If you need a total of four 6pin PCI-E cables, and you only have two, then you will need a bigger power supply. Either that, or get yourself some molex to PCI-E adapters, if you have 4 spare molex connectors (I see that your power supply has 6 total).

    Seasonic makes great PSU's. What's your budget for a PSU and I will recommend some good ones for you.

    Either size will work for you.

    I am pretty sure the majority of all mid-range to high-end power supplies come with those cables. Even one of my 600 Corsair (Builder series) PSU's has those cables. Also, most graphic cards come with the molex to PCIe adapters. You should be fine in terms of connectors.

    Coolermaster PSUs are garbage. I only trust Corsair, Seasonic, and maybe XFX.
