    Ofc they will perfectly work together ..

    What's your budget for the PSU ? and are you overclocking your system or not ?

    I will recommend a 750W PSU at min. and 800-850W if you OC your CPU or / and GPU's .

    As you go for SLI, don't go for the cheaper basic PSU, a good solid one will save you some headache in the future and the PSU will last longer. ( A PSU who is used close the limit all the time will die quicker or give you instability, even if under normal condition the PSU look fine or if the PSU look to work perfectly the first 3 months . )

    Then the brand will depend on your budget for them ....

    One of my pc's is very similar to yours. Same motherboard, ram amounts, and 2 460's in sli. I have been a big fan or corsair power supplies. In 10 years of using them I have yet to have one fail. I use a TX750 watt supply with my setup and haven't had one issue. Always clean reliable power, and from what I've read Corsair under-rates the psu's slightly so you can get closer to the load ceiling in them without worrying as much. They also have a supply for every price budget from consumer to professorial level depending on how much overclocking you are going to do. Whatever you decide to go with good luck.

    Thanks for your answers.
    I didn't plan on OC anything yet, because the graphics cards are already.
    Maybe I will do that later so i thought about 850 W PSU (maybe from Corsair)...

    They are around 200 € maybe I find a cheaper one.
    But as I said it need 4*6-Pin data links for the 2 cards

    Overkill. Go with Corsair TX850 just to be on the safe side although the TX750 would be enough.

    The Cougar GX1050 is pretty decent but the energy efficiency isn't going to be all that great when your system isn't under loads. PSU's are designed for best efficiency in the 20%-100% load range and the system you have in mind would idle under 200W DC. The Cougar is a little higher end affair than the Corsair TX750/850 with the gold efficiency and modular cabling and quieter fan and sharp looking. The Corsair TX's are the "old" CWT PSH design tweaked some over the years...not terribly old...little over 5 years...little bit longer than Corsair has been in the PSU business with their 5 year warranty intro units...go figure lol ;)

    The Corsair AX750 would be a better alternative to the Cougar or maybe a Thermaltake Toughpower Grand Gold 750/850 or Seasonic X750...those are all modular...I like the Toughpower.
