It seems that the race for a mining motherboard with the most PCI Express slots is far from over with the AsRock H110 Pro BTC+ and Biostar TB250-BTC PRO probably being only the start. It seems that Asus is planning on joining the party with not 12 or 13 PCI-E slots, but with 19, though you might be limited to actually using only 16 of them. We already know that you are limited up to 8 GPUs from a kind (AMD or Nvidia) under Windows, so 16 max if you mix them. With Linux though more GPUs from a kind that what Windows allows are usable, but then again more than 16 at this point might not be possible. This is probably why Asus are talking about this product as supporting 16 GPUs even though it does come with 19 slots…

For now Asus is just teasing us with this motherboard and there are no full details about it, including info on pricing and availability. Still it shows that the company has interest in the mining market, especially after also releasing mining oriented GPUs. Unlike some other manufacturers however Asus is showing that they are designing their mining products with miners in mind and not just pushing something that is not worth buying like some others. Their Asus B250 Mining Expert mining motherboard comes with three 24-pin ATX power connectors for directly connecting up to three power supplies without the need to use external means to synchronize the PSUs. There are also three 4-pin Molex power connectors on board for powering GPUs, though you probably will use powered risers and won’t be needing these.

We are yet to see more information emerging, but things are definitely looking interesting already. What you need to be prepared with motherboards for mining supporting so many GPUs is that there will be some unexpected challenges when building the mining rig. Cable lengths, connector spacing, enough space for proper cooling and so on. Design challenges emerge and the more video cards you use, the harder it gets to make things work as expected. Though once you clear the design for let us say 16 GPUs, then the next mining rig should be much easier and problem free to assemble… hopefully.

NiceHash have published some interesting experiments they have done recently, building an 8x GPU mining rig using the Asus PRIME Z270-A motherboard. This motherboard has 7 PCI-E slots as well as two M.2 SSD slots and they have utilized the 7 available PCI-E slots and one of the M.2 slots with an adapter to get 8 video cards working. Their experiment was with 8x Nvidia GeForce GTX 1060 on that particular motherboard from Asus, though other cards will most likely work as well just fine. With the recent price spike and unavailability of cheaper 6x GPU motherboards for mining people are already looking into more expensive alternatives that work well for six or even more GPUs like this model from Asus for example.

It is interesting to note that one of the M.2 slots was turned into the PCI-E slot by using cheap M.2 to the PCI-Express adapter that can be purchased from Chinese sellers on Ebay pretty cheap. You should however be careful if/when using such adapters as sometimes on some motherboards the M.2 slots are shared with some of the PCI-E slots on the motherboard. The Asus PRIME Z270-A motherboard apparently can be upgraded to 8 GPUs using this method, or you can just use the 7 available PCI-Express slots for a seven GPU mining rig instead of the more traditional 6x GPU configuration. The only drawback, the Asus PRIME Z270-A are not the cheapest out there as they use the Z270 chipset and you additionally increase the cost for the M.2 to PCI-E adapter, but then again you also get to connect up to 8 GPUs to a single mining rig (if your PSU(s) can handle that).
