    Sorry what I meant was how many of the extra items would I have one one 12v line.
    Surely I would have to split up the other components onto 12v lines.
    Just was not sure how to devide them up.

    Just make sure the higher wattage parts get their own 12v rail on a multi rail PSU. For instance GPUs on their own rail, HDs on their own rail, etc. Some people prefer single rail designs because you not only don't have to worry about such things, the MOSFETS don't have to switch loads a lot to balance amperage, which adds heat and wear and tear.

    I'm not sure the Enermax Revos are even a good way to go anymore. Lately I'm hearing they're using a different vendor to make them and the quality has gone downhill. The fact that ABS now sells their 1050w unit with a different cable bundle and warranty would tend to lend credence to such words.

    Their new MODU Pro Gold series is likely much better quality, and the money you spend comes back to you in less electricity used, esp if it's a high watt sys like yours and you hold onto the PSU a while. Corsair also has some nice new Gold series PSUs.

    Unfortunatly the pro gold only goes up to 600W
    If I was to look at a single rail psu what would you recomend.

    As your rig is listed there, it's not even possible to overload any of the 12V rails. Connect in whatever way is simplest, and results in the fewest stray cables getting in the way.

    Also, a 1000W+ unit is pretty serious overkill. A good 700-800W unit would be plenty for a rig using a pair of 5770's.

    Enermax currently has MODU87+ Gold PSUs that go up to 800w, and more coming that range much higher than that. Design on current and new ones is tri and quad rail depending on wattage.

    If you want single rail, consider Corsair's AX Gold series, which should be available soon. They'll have them in 750w, 850w, and 1200w. I like Corsair's design because it's high amperage, server grade parts/design, and single rail. They didn't take an ATX PSU and make it Gold standard, they adapted server design PSUs to ATX. Because of that they have revolutionary features that keep them very cool and quiet, like zero voltage switching. From what I'm hearing they'll also be priced well too.

    According to a recent preorder sighting on Amazon, they're already showing at...

    AX1200 - $278
    AX850 - $187
    AX750 - $164

    ...that may not seem reasonable to some, but considering how well these are made, it's quite good.

    Thanx for everyones input.
    I might go with the Corsair.
    Only thing is I think the 1200 is way to much and the 850 not enough spare if I want to upgrade in the furture.

    I agree, the difference in amperage output between the 850w and 1200w is huge. It would be nice if they had something in between that had at least double the amperage one 480 requires (84A). You don't actually NEED that much for dual 480 SLI, but it's nice to have for headroom, folding, or extended hardcore gaming over a period of years.

    The Enermax 1100w may be worth looking at, esp if it's priced a fair amount below the AX1200. It will probably have at least 87A, because even their Revo85+ 1050w has 87A. I also doubt their Gold series is made by the same vendor their Revos are, and even if they are, thy're no doubt made with better parts and build quality.

    Best thing to do on a high end PSU is wait if you can until it's been thoroughly tested by a site that does such things, like jonnyGURU. They just tested the Kingwin Lazer 1000w, another Gold rated PSU, but it did not score high like the AX1200 due to poor ripple performance on the 3v & 5v rails. At 83A, it falls just shy of double the amperage of one 480. http://www.jonnyguru.com/modules.php...Story&reid=191

    The Lazer 1000w is priced at only $190 though, so it's in the ballpark of the AX850 with more power.
