Check this link to see what kind of power is actually drawn from those cards, It also explains that the x1800/x1900 series require the crossfire edition card for the setup as well. Wish it could have two xtx's but I found that out, cancelled my order and got the 1900 CF instead. Under load though the x1900xtx with the x1900 CF card draw 414-425watts, and like 10-11amps so they are power hungry. Read up on the article though, I enjoyed it, and found it to be very imformative.

I'm not clear on something... It shows that the x1900xtx and x1900 CF cards under load will take up 470W (280 + 290), but it says only 425 W in the text. That's a difference of 6A, so it's quite a lot... Which is correct?

Judging from pictures on page 4, it shows like 414.1 watts and that's comming off a meter, so I don't see how that could be wrong. I would assume when you have the cards powered seperately they would use more power, when you put both in, the load gets divided between the two I guess, and actually is lower then the two apart.

Also, that was total system power reading, i.e. that includes the power hungry FX62 they used as well, right?

yup, and they also stated that the X1900XT(X)'s draw 100-120W each. Thus, they need max 10A per card under full load (not OC-ed). Add a bunch of Amps for OC, say 5A, then the total for 25A. With the PC P&C you can hang both X1900's on the 36A rail (which it is designed for) with Amps to spare. The CPU will draw from 1 16A rail, and you'll have the other 16A rail to spare.

No worries here.

Good, I decided not to RMA my PSU because of the fact that the motherboard and cpu will be sucking a lot of the 16A rail under full load with my setup, so I figured it would be best to have the 2 12V rails for the CPU/motherboard. I'd also rather have room there since I'm more likely to have a full motherboard than 2 x1900xtxs, but it's nice to know I can overclock my system with this setup and still have plenty of room for more drives than I'll ever need!

My reasoning sound good?

Unfortunately though, we can't run two x1900xtx, need a crossfire card for that series (xtx+CFversion is about the best we got)

I thought that changed with the 3200 chipset?

Reviews seem mixed. I have read websites that claim they tested with dual X1900XTX's and those that claim a Crossfire edition is needed. My current point of view is that it is possible to have dual X1900XTX's, but that you loose some capabilities in AA and so on (you still can do AA, but not all the way; something like that). I'll do more research on this item.. it's a bit confusing and a lot of contradicting information. For sure is, no way you can do dual X800's or X850's; for those you need Crossfire Edition card
