Is PSU sufficient for this build?

- I'd like to know if this PSU Enermax 720 watt, is sufficiently powerful for running a 8800 GTX + an Q6600 quad core?

- Am I right in saying the 8800 takes a supplementary 12V rail (in addition to the PCI-E power)?

- Does the CPU take supplementary power as well? I can't seem to find the info I need.

Thanks for any help.

Edit: Oops, didn't see PSU subsection of the forum. Move please :)

  1. Link broken :/

    If it's the Enermax Infiniti 720W, then it's way more than enough, you did good choosing that one. And the 8800GTX needs 2 additional PCI-E (6 pin) power cables aside from the power that is provided by the PCI-E 16x slot, but don't worry the Enermax Infiniti 720 comes with 3 additional PCI-E cables, so you're covered.
  2. Am I correct in my understanding that this PSU then wouldn't be sufficient for a dual 8800 GTX build (in the future) because it only has two PCI-E rails?

    If so is there any way to convert any of the other rails?

    (Yes, I'm a noob, its my first build, but I've been doing my component research :))
  3. Dude, your PSU could power a rocket if you actually set your mind to it. I'm pretty sure your GTX brings a 2-Molex-to-PCIe cable (I know my 8800GTS did even though I don't use it), so with one of those cables and the other 3 PCI-E that are on the PSU you are pretty much covered.

    Molex= 4pin for fans and optical drives.

    EDIT: in case you're wondering, I mean one of these:

  4. You're right, it does!

    Thanks :)
  5. That should be a good PSU for two, I was advised a 750W Would be more than enough for a similar build. Just waiting on my CPU delivery tomorrow!!!
  6. To confirm that PSU will definitely be fine for a single GTX and should indeed run two in SLI without any problems.
