In the GPU mining world, having tried pretty much every motherboard out there, I have settled on the B250C Mining Motherboard.
As you can see this motherboard has 12 USB “style” ports, so instead of using the small 1x adapters or 4x or 6x PCIe splitters, this motherboard does all the PCIe splitting onboard.
I’ve built a lot of mining rigs and I’ve used every 4x and 6x adapter out there and pretty much every mining motherboard there is.
Hands down, this motherboard is one of the easiest to use and has been a gamechanger for wiring up a rig.
I now have about 10 of these in operation using immersion cooling and one of the great things about this motherboard is that it comes about 99% setup in bios. The main thing needing to be changed is the PCIe ports from Gen1 to Gen2.
Speaking of BIOS this board has pretty much every setting you could ever dream up available in bios. In my twenty five years of IT work, I have not even seen this level of available BIOS settings on enterprise server grade stuff. I was impressed.
One of the first things you’ll notice is there is no PCIe 16x slot or any other PCIe slots to plug a GPU in and that’s because you are not supposed run a GPU on it except for the USB style ports.
So in a general setup, your risers (good ones) will come with a quality USB 3.0 style cable. If you need longer cables you’ll have to experiment, but I have found some 3,5,6 foot cables that did work. But PCIe signaling is very sensitive so if you need longer cables, test and verify it works. Otherwise the cables that come with your riser will work just fine in most builds. You just have to keep in mind, if you are building a 12 GPU rig, the GPU’s on the ends could need longer cables. I didn’t need longer cables generally as most of the bare minimal frame rigs I used with Nvidia A4000 gpus didn’t need it.
I’ve had these motherboards in operation for a while now and it’s very much plug in play (but change the PCIe ports to Gen2) and they have been rock solid. I have shown then on my youtube channel with my immersion cooling setup.
Price is generally good but does go up and down. You can find these on ebay sometimes a little cheaper but with longer shipping, just be careful if you go ebay as some sellers are not selling the quality part but a cheaper knockoff. Generally the US shippers are good. That said, if you would like to buy one you could use my amazon link below. I make a small commission and that helps support me in writing these reviews!
