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...  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. |

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 |

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 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... |

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.

Put a couple of intake fans on the front. |

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. Matthew |
