PCI-E power requirements?

[Pabby]

Hi, I'm pretty experienced with PC hardware and I'm thinking about upgrading to an SLI setup soon. I'm interested to know what the power requirements are for PCI-Express cards?

I'm a little confused about PSU's. I've been seeing PSU's about with 24-pin main connectors instead of the usual 20-pin, will I need one of these? And what about the cards themselves? how many connectors does each 6600GT take and what kind? I've also seen special PCI-E x16 connectors which i assume go in to the x16 card, how many will i need for each card and will they then require any additional connectors?

Basically what connectors should be on the PSU I need?

EDIT: Corrected to PCI-E not PCI-X (I'm a silly monkey today)

First off, its PCI-E, not PCI-X.

You will need a 24pin PSU, if you get a PCI-E motherboard. Unless you want to fool with a 20 to 24 pin adapter. If you are buying new, I would just get a native PCI-E PSU, less cables, and it will have a PCI-E video card plug.

If I am not mistaken, the PCI-E 6600GT's do not additional power. So you wont need to plug in any thing into them.

if your thinking about sli, you'll want a mobo with pci-e connectors (6-pin) if your going to be using a 6800gt/6800ultra, their are adaptors from molem though i think
