Crossfire 5850's with 650W PSU?

I'm looking into building a PC with a X4 955, 2 HD's, and for now a single 5850, but would like to add another in the future.

This seems like a pretty good deal, just wanted to verify that I could run two 5850's in the future with this PSU.

    First, the system requirements!

    Here are the official power requirements for the ATI Radeon HD 5850 and HD 5870 video cards.


    ATI Radeon™ HD5850 System Requirements:

    PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard

    500 Watt or greater power supply with two 75 watt, 6-pin, PCI Express® power connectors.

    600 Watt or greater power supply with four 75 watt, 6-pin, PCI Express® power connectors for ATI CrossFireX™ technology in dual mode.


    ATI Radeon™ HD5870 System Requirements:

    PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard.

    500 Watt or greater power supply with two, 75 watt, 6-pin, PCI Express® power connectors.

    600 Watt or greater power supply with four, 75 watt, 6-pin, PCI Express® connectors for ATI CrossFireX™ technology in dual mode.

    The power supply recommendations are for an entire pc system.

    Second, the power supply!

    The XFX power supply you linked to is a very good psu. It should not have any problems powering your system with two 5850's. Here is a link to a competent technical review:

  3. Size looks good but is a good PSU ? All I could find was this:

    The Black Editions fared better:

    but considering the price on that one on newegg, I don't think they are in the same league.
  4. Jack - never mind! Too many models! Confuses the heck out of me.
  5. I believe the one on newegg is the same as the one you linked Jack(the first link) and the same one Johnny linked as well.

    Even though the model name doesn't say XXX on newegg, the model number listed: P1-650X-CAG9 is the same model number for the 650 xxx listed on XFX's website
    http://www.xfxforce.com/en-us/products/psu/xxx/P1-650X-CAG9.aspx

    Also, according to XFX's website, they only make one model of 650w power supply, so it's gotta be the same one as far as I can tell.
