  1. It should be fine. That is a good PSU.
  2. That PSU will run nearly any (2) card setup. 6950 in CF requires a 750W PSU with 48A on the 12V rails with (4) 6-pin PCIe connectors.
  3. good to go with that PSU
  4. Sorry to bump this posts guy,
    but i have this PSU right now, i wonder if he can be used for CROSSFIRE my 2 hd6950 :)
    thanks again!

    plenty of power for that set up
  7. For a system using two ASUS Radeon HD 6950 DirectCU II graphics cards in 2-way CrossFireX mode a minimum of an 750 Watt or greater power supplywith a combined +12 Volt continuous current rating of 58 Amps or greater and have at least four 6-pin PCI Express supplementary power connectors would be recommended. That's enough capacity to handle running both cards manually overclocked to a core clock of 970 MHz and running Furmark.

    The Zalman HP Series 850W (ZM850-HP), with its combined +12 Volt continuous current rating of 64 Amps and with two 6-pin and two (6+2)-pin PCI Express supplementary power connectors, is sufficient to power your system configuration with two manually overclocked ASUS Radeon HD 6950 DirectCU II in 2-way CrossFire mode.
