Hello everyone,

So I was watching an ebay auction for a while for a SuperMicro CSE-848XA-R3240B Barebone Server. it appears the chassis was originally meant for this system using a proprietary form factor X10QBi motherboard. I was mainly interested in the SAS3 backplane. So I got both of them and they indeed both had the BPN-SAS3-846EL1 backplanes inside along with 2x CBL-SAST-0531 cables in each.

The PDB in each are massive. PDB-PT418-B6824. I thought perhaps it would be two seperate PDBs and maybe I could use one in my current CSE-846 chassis but instead this thing is way bigger In retrospec it's listed right on the product page. The chassis each came with 4x PWS-1K62P-1R power supplies. These PDBs have a massive number of power connections on them, seems like I could use them for almost anything.

It also contains a FPUSB8813 board which is next to the 4x PSUs. It has a cable that looks like it runs to a USB header.

One thing I didn't realize is how much longer this chassis would end up being compared to the CSE-846. In retrospect it says it right on the product page. 32.1" depth vs the CSE-846 depth of 26".

With all that out of the way- what do you all think I could potentially use these chassis for? The mount points inside I assume are for the X10QBI motherboard. They can be moved around though and there appears to be a decent number of other positions.

Does it look like an ATX board could be dropped in here somewhere? No normal place for I/O though. I suppose even if it's silly given it's size I could try to drop in a JBOD controller and use it as such? Not sure if I could use the exisiting PDB unit with smaller PSUs perhaps.

What do ya'll think could be the best use here? Here's a picture with the backplane and PDB removed for now.

I’ve got one too. Same question except I want to stuff this full of double width GPUs.

Can’t decide on a motherboard. The standoffs will fit anything since you can move them around. And I’m not too concerned about the built in connectors lining up—they won’t. Can deal with that by adding an Asrock Paul card.

That power distributor also has 4 headers to power GPUs just need the supermicro cable.
Has anybody tried to use the pws-1k28p-sq power supplies?
The supplies that come with it are 23 pin also.

Edit: looks like it might have 8 headers for GPU.

cbl-pwex-0581
it is just a 8 pin to pcie 6+2 that is 65cm long

there are other Supermicro cables that are identical except a lot shorter

Can i just use any of the 8-pin to 6+2 cable to connect to GPUs? I mean, with other PSUs I have like Corsairs, etc, I get a few of these cables. Can I just use these cables in place of the CBL-PWEX-0581?

I can just connect the GPUs using the connector circled right?
I would not do that the pin out might be different than yours.

You do not have to get the long one that is specific to that case but I would get the supermicro part or find the technical detail on the cable so you match the pin outs

But that is the correct connector on the PDB right?

did you end up using a standard motherboard? Were there standoffs for normal board sizes? Looking to get one of these and there looks to be enough standoffs but I wanted to check and see how it went with you guys that picked one up
