1k is probably enough for 5 x 5830's, so I am looking at smaller PSUs:

I think the above PSU would be sufficient for 3 x 5830, unsure about 4x

I am thinking either one of these would be sufficient for 4 x 5830

I'm actually only running three of them, because the top PCIe slot on my motherboard is dead. But the bottom one is too close to the bottom of the case to use without an extender.

And I use that exact PSU for 3 of them. I have a feeling it is overkill, but oh well. I bet it would run 4 just fine...

You are using the CORSAIR CMPSU-750TX for three of them?

Yes, works just great. I have one of them overclocked to 975mhz on a little more voltage too... would have overclocked all of them, but I couldn't figure out a way to do it with Trixx.

Just FYI, my 750TX just died last night. I was running 3 5830's and a C2D processor (50%-60% usage). I suspect heat had something to do with it, as the air coming out of it was always blazing hot, and I don't have any case fans (just left the side panel off). Still, it may be insufficient for 3 5830's, so I thought I'd send out the warning. I bought an 850w ThermalTake to replace it, as that was the only decent PSU available within a 2 hour drive. Now I have the case laying on its side, so less heat will be directed through the PSU. We'll see how things go this time around...

Hey Sgt --

Are you one of those who thinks a 5830 is wasted unless it's OC'd to the 300+ range?

Personally, I have my 5830's bringing in about 270 MH/s each. After all, it's not like they ARE a 300 MH/s card -- that's not exactly their stock output. I don't do aggressive OC'ing.

My point -- did you have them overclocked much? Because if so, they use a lot more than 140W each.

I have 3 Sapphire 5830s in a case, but they keep getting too hot. Top one was at 102C when I had it overclocked, but I backed it down. It's now at about 92C. To keep sound down, I'd prefer to keep them in a case, and it also protects them from my pets.

How can I cool these things if they're stuck in a case? They have a 1/2 centimeter of space between them, and the case already has a top fan and a side fan. Help please.

I'm getting this fan just waiting for it to be delivered.

Put a couple of intake fans on the front.

I know you can use cables so you don't have to have a motherboard that have all the slots but I was wondering what strategies or things or cases people are using to fit them in. Since I need to place them somewhere that isn't where I live, I can't have it open air otherwise I would do it.

Why can't you do open air?

4 cards in squeezed together inside of a case will not work... not at stock clocks at least... you will probably have to underclock them (gpu and mem) to get your temperatures to an acceptable level for running 24/7...

Thanks for the warning. I will be using a 1K psu if I was to do 4 of them. Also do you regularly check the temp? Did you know how hot it got? I've been running mine pretty hot (low 70s to low 80s) and the cards seem to work fine (5850s etc).

I will be getting the new stuff this tuesday so we'll see what happens.

The temps of the cards were generally 70-85c. I didn't check the temps of the PSU (is that even possible?)

Do you think that if the heat from the cards hadn't been directed to the PSU it might not have died? I am running caseless setup

Certainly possible. I know that much heat doesn't help a PSU run its best, so it might just have died due to the heat. Hard to say whether it was overload, or heat, or both. I need to just hook it up to my battery backup to see how much it is actually drawing, but don't want to shut down my server to do so.

I wouldn't take the chance, four 5850s...? maybe, but 5830s use more power than 5850s and almost as much power as 5870s, if you OC them they'll probably use about about as much a quad 5870 setup, would you trust anything lower than a 1kw PSU with a quad 5870 setup...? I wouldn't...

Get a single rail PSU otherwise you have to dick with adapter cables to get power from all the different rails.

I ordered that case.. we'll see if I can do this. Will be interesting to see. I just wish I could extend the slots longer then 7 inches so I could put the card on the front.

with four cards in a closed case your overclocking limits will be quite tight unless you manage to somehow create a very good airflow through that case...

I actually have 3 5850 sapphire Xtreme OCed to (372mhash) in a case (coolermaster full tower) with very little issue. I just need a way to stick 4 cards in a case somehow but maybe 3 is the way to go as I know it'll work (IE fit in the case). Too bad this mobo (http://www.newegg.com/Product/Product.aspx?Item=N82E16813130274) doesn't have the pic-e 1 on the top.. that way I could actually balance a 4th on top.

Temps?

low 70s and extremely stable. It has been running without a hiccup for 2 weeks now.

I found that cooling becomes an issue even with 2 x 5830 (OC'd) with a closed case, and so I keep the side off of my case, and my other rig is currently running caseless. Running 4 cards in a closed case... I don't know, good luck!

From my own testing, each 5830 card uses about 140W. A base system will need about 100W, so 520W for 3 (69% of 750W PSU), 660W for 4 (88% of 750W PSU, 77% of 850W PSU).

With that said, the Rosewill PSU you linked appears promising. It has four 12V rails @ 20A each - convenient for running 4 cards that seem to require less than 20A. One of my 2 x 5830 rigs uses a 550W PSU with +12V1@16A, +12V2@17A.

So the question I have whether to run with 4 rails or 1 rail.
