Need PSU advice for my new system

  1. I'm getting a new pc and i wanted to get some input/advice on the PSU. I need a PSU that will power my system and 2 8800 GTS in SLI. I'm not getting 2 cards right away, i will be buying 1 for now, but i would like to have an option of adding one in the future so thats why i need something to power 2 cards. Also i'm getting a power-hungry FX-62 processor which requires 125W as well. I am currently considering 2 PSUs: OCZ Game X Stream 850W or Enermax Infinity 720W

    My system specs:
    AMD Anthlon 64 FX-62 Windsor
    Asus M2N32-SLI Deluxe
    2 GB of Corsair TWIN2X2048-6400C4PRO
    2 8800 GTS
    150 GB WD Raptor
    250 GB Seagate Barracuda
    Zalman 9500 AM2
    Lite-on SATA DVD Burner
    Mitsumi Floppy and card reader
    Creative X-FI Extreme Gamer
    Creative inspire P7800 speakers
    PS/2 Keyboard and mouse

    May also add an OEM SATA DVD-ROM

    Any thoughts on my PSU choices or recomendations for something better?

    Go above 700W

    I'm sure you know this, but go with at least a 700W. I've got a Rosewill 550W and I love it. Nice chrome casing with blue LED's and generous options. Even has a fan setting on the back for OC'ers.

    Yes, i know that, thats why i'm considering these 2 PSUs. But what i don't know is how many Amps on the 12 volt rails i need and how many 12v rails should a good PSU have.Both of these are certified by Nvidia for dual 8800GTS but i've heard stories of certified PSUs not having enough power for everything so i dont trust their certification.

    Here's the info on both PSUs:

    Enermax: +12V1@28A,+12V2@28A,+12V3@30A

    OCZ: +12V1@20A,+12V2@20A,+12V3@20A,+12V4@20A

    Anyone know if either will be enough?
