It's been floating around that the GX2 card releasing next month will have a minimum requirement of 580W. This seems a little rediculous to me, but since it is 2xGPU's in one I suppose it's possible. Does this mean you should be getting AT LEAST a 700W PSU if planning to buy this?
580 watts with 40 amps. You can get a toughpower 650 that puts out 72 amps so I wouldn't say you have to jump right up to 700. Now the bit I don't believe is the $450 price tag. With 30-50% more performance than a $650 ultra? Some how I doubt they're just suddenly going to go "oh yeah, and lets stop screwing them with the prices"

With you on that. I wanna see the true price range of the card. Where did you pick up the info about the power req?
One thing is for sure, you'll need an 8pin + 6pin PCI-E connector for the power requirements rather then just 2 x 6pin PCI-E connectors. My PSU has 1 8Pin + three 6Pin PCI-E power connectors, my PSU (Enermax Infiniti 720W PSU) can handle only one graphics card that uses the full bandwidth of PCI-E 2.0.

I saw it on xtreview. I doubt it will use the 8 pin. From what I can tell its based on the 512 gts, which uses one 6 pin. So it will most likely be 2 6 pins.
My Zalman 600 Watt puts out 42A on the 4 12V rails, it also has two 6 pin connectors, does everybody think that will suffice for the new 9800GX2 ??? I really dont want to buy a new one, it was very expensive, and has been a fantastic PS.

I wasn't guessing that the 9800GX2 will use the 8Pin + 6Pin connector, I am telling you that it has already been comfirmed that it will use one 8Pin and one 6Pin. Thats a fact.

Why can't they use 2 6pin connector? Not enough power?
I believe PCIe 2.0 supplies more power than the old PCIe so perhaps one of the connector isn't necessary when running it on PCIe 2.0?
The PCI-E 2.0 was updated more for the extra power draw that will be in use soon, as for the extra 16GB of bandwidth we are far away from using it anytime soon. The extra two wires added to the 8Pin PCI-E allows 150 watts compared to the 6Pins 75 watts of power. By this time next year all mobo's will all have PCI-E 2.0 slot, the X38, X48, 780i and the 790i already have the new PCI-E 2.0 spec. My power supply is DXX or PCI-Express 2.0 ready.

I'm just thinkin if the card is going to take up like 580W and the processor another 60W, that's already 640W, and I was originally planning on getting a corsair 620HX modular.. but now it looks like the 750W corsair (non-modular) is my best bet, unless someone can recommend a nice modular PSU with long cables for the p182 above 650W.
Use this for comparison purposes:
1-8800GT = 400-450w @ 22-26amps
Nvidia released the 8800GT power requirements a few weeks before release for the GT.
Only thing for sure is 1-6pin and 1-8pin pcie connection will be required.

I don't think it's a case of them having a change of heart, rather nVidia having to compete with the $400 price tag that AMD has said the hd3870 x2 will have.

it doesnt go that way...it needs 580W in reserve to powerup but that doesnt mean its gonna consume 580w...hell its not gonna be half of that even, at full load.
the 8800 ultra consumes about 250-260watt at full load, and they said the upcoming GX2 will consume less power so you do that math m8.
i highly recommend thermaltake toughpower cablemanagement 750watt...you will never need to change it again and its quite cheap...110bucks or so...and gives 72A on the 12v which is awesome
