Power consumption of the cards in SLI is just insane:
http://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_480_SLI/26.html
624w just for the cards!!! They are going to struggle to get an X2 version out and keep it within 300w if they're already breaking 300w with a single card. Chopping up the specs and underclocking 2 GPUs to get around 300w will probably mean performance will be around an OCed GTX480. A die shrink will hopefully fix that issue.
Got a link? And that's still way over the 300W PCI-e spec.Thilan, if you're going to keep mentioning this in various threads, you might take an extra second to say that this is running stress testing apps like Furmark. Peak SLI'd 480's are under 500W. Actually they say 472W.

It'll be the ASUS ARES, it says so right in the link.I wonder what this will be......
Either/or, doesn't really matter. Reading my comment, it isn't clear what I was going for (and now that I reread it, I think I misread your comment as well). The test "Peak" shows 472W power consumption for both cards, but it's only using 3DMark03 with high IQ settings as a test. Furmark isn't really an accurate "real world" power consumption test, but in all honesty, I'm not sure if 3DMark03 is either, given the age of program. I'd be much more interested in seeing someone record "peak" power consumption numbers when running a game like Crysis or Metro 2033 as an indication of "real world" power usage. I was wondering if you had a link to such data, since you seemed to indicate that 472W was a more accurate number (unless I misinterpreted your statement).What are we talking about here? SLI'd 480s? Or any potential X2 card based on GF100? Which way would you like the conversation to go?
As for a link, and my comment, it is right in Thilan's post, and it pertains to SLI'd 480's.
Showing 236W for each if you split the 472W. That's 236W per card, per PCI-e slot which does not exceed the PCI-e spec. Not any X2 card that we can only speculate on what they're going to do to produce one. I haven't any idea in that regard.

Interesting. Are there other applications that would push the card that high(maximum), or is furmark the only thing that uses everything the card has to offer?
I wasn't trying to go around parroting that in various threads (it's only in 2 anyway). I meant to only mention it here but then saw a thread where somebody actually asked about the power consumption of GTX480 SLI which I would think very few people run (ie. I never really expected anyone to ask about that). And that 472w seems unrealistic...3DMark03 at 1280x1024 is not really going to be pushing the GPUs very hard is it?
Can someone look at the xbit labs numbers as well. While they do not have the new fermi cards included in this review, their numbers are quite a bit higher across the board on power draw compared to the techpowerup ones. Which leads me to wonder what the difference is in the test methodology.

EDIT: Just to clarify, that 624w is for Furmark.
A dual GPU version is entirely possible, just not of the highest SKU (when has it ever been...?).
Get a couple of low voltage GTX470's, stick them on a single board, and it might manage to come in with reasonable power consumption.
