2 Rail or 4 Rail PSU?

I'm building a new system but i'm a little confused about selecting a power supply.

CPU - Athlon 64 FX-57

Motherboard - Asus A8N-SLI

HDD - 2 Maxtor 300gb SATA + WD 80gb PATA

Memory - 2x1gb Kingston HyperX

Video Card - 2 BFG 7950 GTX 512gb

Sound Card - Soundblaster X-fi Xtremegamer

Optical Drive - Lite-On Lightscribe DVD-RW + Sony CD-RW

Case - Cooler Master Centurion 5

I was thinking about going with SeaSonic M12 SS-600HM (http://www.newegg.com/product/product.asp?item=N82E16817151030) Which is a 4 Rail PSU, Is this going to work or do I have to have a 2 Rail PSU?

More about rail rail
  1. i would suggest 1 8800gts or 8800gtx.

    the fx-57 is a great cpu but i would also suggest a dualcore instead.

    yes that psu should work fine.
  2. Two rail or four rail doesn't make a lot of difference unless you have so many hard drives that you need all the rails. The bigger thing to look at is the amps per rail.

    Like sirehck said, the FX57 is a good cpu, but its very dated. The future lies in dual cores. It depends on what you plan to do with the machine.

    The psu you picked looks good. You shouldn't have any trouble with it.
  3. Why not C2D system if you haven't already bought your stuff. Its better price/performance than AMD for now. If you didn't know.

    2 rail should be plenty. Make sure you get a good brand though.
  4. Just like everyone is saying it would be wise choice to go with a c2d setup. Best bang for your money.
