As for dual power supplies, a quick mod that links the Power On signal cables on both units should be sufficient for using both at the same time. Look for a tutorial though; I've never done it and I'm not sure.

The only other option is a flexible adapter that extends the PCI-E slot along a ribbon like cable about 6 inches which could also work. For the powersupplies there is actually an adapter that hooks up both of the 24 pins into one so that both powersupplies work at the same time without ahving to use a paper clip or anything like that.

Take a look at this thread, it's pretty much what your doing except your config is far more powerful.

And here's rough guide of how to jump start the second PSU for your build,

Yes, they do make 1500W power supplies, but they're pretty expensive. If I do need 2000+ Watts, then 2 x 1000W or 2 x 1200W power supplies will be much cheaper. I guess I'll just do something more similar to those pictures they posted where I don't really have a case. Now I just gotta figure out how to build such a thing...

Luckily, I won't be paying for the power. I have an office on campus where I can set this all up.

Also, the bandwidth isn't important, so putting a 5870 in an x1 slot should be fine. In the end, we'll see how many 5870 cards I can actually fit into some kind of setup. If it's not 8, then maybe I can make use of some of those single slot cards.

I rememeber FASTRA saying that they had to get ASUS to make them a custom bios that supported 8GPUs, since i think by default they only supported 7.

(fastra is a budget supercomputer that uses GPUs)

Sorry if this is completely dumb, but would you make do with 8 5770's? They come in single slot, and although their not as powerful as 5870's, they won't require hunting down risers and strapping two PSU's to your rig just to run them. I know your not posting your "secret" project, but I assume it requires DP, so 5770's are out of the question?

Btw, that single-slot 5830 is beautiful. Wish they did that with the 6950...

Where would one go to acquire risers like that?

Just for curiosity's sake.

Now that I think about it... maybe I should just use 4 x 5970s? There would still be 8 GPUs, but it would use less power and it could fit on a normal motherboard in a normal case. Of course, 2 x 5870s seems to be somewhat better than a single 5970 for some reason, but maybe the difference is not too big. Does anyone have some idea of the performance difference?

You're going to get more raw performance out of the 5870 setup, but the 5970 will be more efficient. But, since you're not paying for the electricity....

Also, remember that Windows won't even recognize that many GPUs, so you'll have to run ubuntu on it.
