Description

Our fourth computational GPU analysis machine running SBGrid software with Relion. Primary use will be computational analysis of CryoEM data in the field of molecular biology.

System is running CentOS 7. There was an attempt to use CentOS 8, but NVIDIA drivers for the RTX 2080 Ti were not readily available from NVIDIA nor ELRepo during construction of this computer.

Power supply is not compatible with this case.
This case offsets the power supply from the back with a custom plate, then uses a one foot C14 extension cable to connect to the power supply. However, the Corsair AX 1600i power supply uses a C19 power cable connection. The existing cable had to be removed and a new adapter had to be custom built and then installed. The original plate was able to be repurposed, but with some minor modifications using a Dremel.

A 1600W power supply was used with the intent of adding two more RTX 2080Ti, and five more 3.5" hard drives to accommodate future growth.

This is my second build with a case from Be Quiet!. I love the design and the construction, but there are elements that make it very difficult to work with. The back side panel does not go back on easily due to posts sticking out half an inch that grab any cables as you slide it back on. The side fan cover must be removed then reapplied to remove those posts. In my opinion the side fans are not necessary and don't ever seeing myself building a system that would need additional fans on the side the way this case intends. As beautiful of a case as this one is, I would highly recommend NOT buying this case for anyone that frequently opens their computer.

That's a lot of power!

See my other build with 4 2080Ti's.

you can only have 2 2080 ti's in sli and you also need a sli bridge

You only need an SLi bridge if you're running them in SLi. I am not doing that. These are computational biology machines.

I understand you now.

Wait, are both of those 2080ti's the same model? It looks like the power connectors are in different spots.

Good eye. I have another system with 4 2080Ti's that would randomly power off when we used the 4th card. Since I was building this system it was really easy to swap in a new card to test and see if that was the problem. The problem was the power supply, so I didn't bother switching them back. The other system has a EVGA 1600W, but that model has proprietary cables and I didn't want to rewire the entire thing so I could test it with the Corsair I bought for this system.

hey, so that 9800X CPU, why'd you get that vs the 9700K? is it for the 44 PCIe lanes? think there's a performance difference?

Hey, I am curious how hot do those blower cards run on full load?

Sorry, but i don’t actually think that you can do 4-way sli with 2080tis.

Since this is a Linux system being used for GPU compute, it's likely that OP doesn't need SLI at all. Most multi-GPU workloads, e.g. crypto mining, don't need it.

that top gpu has not air

Its a blower style card. forces hot air out the back instead of drawing in fresh air from the case
