The biggest Pro that I see is : 3 x PSU Headers on the board mean you do not need to externally link the PSU's, you can directly connect them to the motherboard and they will all be started together by the motherboard.
That, and the reduced hardware costs and cheaper OS/monitoring service - only one copy of ethOS, SmOS MinerstatsOS needed so the fee is one third.

Ofcource I personally haven't even crossed 8 GPU per board for fear of stability, and to avoid multiple PSU's and the complexity they bring. But this makes me want to get one just to experiment with it :D

Once again, would request our asian friends to keep their eyes peeled, and let us know when these show up in retail.

While it is definitely cool from a technological Gee-Wiz standpoint, I agree that it is getting a bit ridiculous. There is certainly a cost efficiency and management reduction by running multiple GPUs off a single motherboard, but at some point one needs to ask where is the optimal point.

Pros
- Decreased system cost as the Motherboard, RAM, CPU and storage (SDD or other) costs can be spread across more GPUs as they are added.
- Less administrative management of rigs as one 18 GPU rig is easier to manage as far as updates than there is with three 6x GPU rigs.

Neutral
-Power supply requirements stay about the same as it is mainly GPU driven. With the looks of the motherboard, it is expecting at least 3 PSUs anyway, which would be the same requirement for three 6x rigs.

Cons
-If one GPU crashes and causes the rig to hang, lockup, or fail, you lose all 16 GPUs of mining power during the downtime. With multiple rigs you spread out that risk.
-Introducing multiple PSUs into a single rig can cause more overall instability than a single PSU rig.
-Complexity, each additional GPU can add more complexity as far as drivers, OS support, stability, just general troubleshooting, etc.

I can probably think of others with time, but for me the optimum sized rig would be somewhere around the 6, 7 or 8 GPUs per rig ballpark and running on a single PSU.

seems like one of the better though out mining boards. 3 molex for pcie slots, 3 atx psu connectors. seems like you could make a cleaner setup on that board.

This looks really nice.

and the 3 atx  connectors looks nice, no more add 2 psu needed or whatever cable.

Only thing i can see that would have been nice is the on/off/reset button as on h110 pro btc one.

other then that im drooling  ;D

I am in agreement that this is too many GPUs to be considered viable. I mean really, at this point how are you going to cram all those risers with the extension cables into that area? You are going to run out of space and wire length! You will have to buy extra expensive 2 or 3 meter wires if that is even possible! Really cool idea but I just do not see this working out well. I can still buy a mobo cpu and ram to run 7 GPUs for like $200ish - that is working very well for me and I do not really want to do higher than that.

I guess this is only for linux right, windows can only manage 8 amd and 8 nvidia cards.

I like the 3 atx psu connectors

Looks good AF. But 19 GPUs... i would love to see uptime statistics on someone using this.

I guess you missed Biostar one that supports 104 GPUs

For the guys looking to deploy GPUs in the 100s this makes perfect sense

Latest update of Windows 10 has added more GPU-s support but still I am not confident that they will run without problems in Windows. I guess too this is Linux territory as there you can add as many GPU-s as your board supports and Linux is much better in handling more hardware than Windows is.

does Z270-A PRO support 9 gpu? when moded bios?

IMO, one other issue to be sorted out for the GPU's is managing power consumed per unit volume, since the majority of risers are only available in certain lengths.

Maybe the next rev of GPU mining is mounting the GPU's separately in some sort of open air, weather protected enclosure, against the outside wall.

Do you have the source?

nice work, the interesting thing is price, I'd like to buy it around 150USD.

Any official source avaiable? Right now I can buy asrocks h81 with cpu about 50$, so if the price will be that high as the asrocks h110 is (180+$), then its pointless.

The 3 ATX is most likely if you are using the old ribbon risers which require the +3.3V line.

If you connect the 3 ATX from different PSUs together it will kill all the PSUs.

Pretty sure that's the reasoning for the 3 ATXs.

I can tell that you are not familiar with Servers and there power supplies.  This mobo has a built in Power Distribution Board that will do a 1+1+1 PSU configuration so it will total the entire 3 PSU's for a single wattage!   

Server's have had this capability for a long time now.  You can run server PSU's as a 1 + 0 which means that one PSU is redundant in case one goes out or if you have a lot of devices or GPU's in the server you can run the PSU's as 1 + 1 which is additive for the wattage needed to run higher wattage.  Dell has a server that has 1 + 1 + 0 so it adds two PSU's and the third is redundant in case one fails.

Holy Moly ... this really is getting absurd. Even without the "Risers" that motherboard has 22 PCIe slots. How are you going to connect 19, or 22 or 104 GPU's to one motherboard? How will you design a lattice around the motherboard and the PSU's that are almost equidistant, since longer USB cables cause issues.
This is beyond practicality now.

it wont work my boy, most cpu support 16/32 pcie lines, and amd threadripper only support 64pcie lines, core i9 only 44 pcie lines

Take a look at this video - https://youtu.be/SB7T94PaNDo  Similar riser card concept.
The key is using the PLX Technologies chips that you can see in the video - http://www.mouser.com/ds/2/38/PEX8712_Product_Brief_v1.0_20Oct10-514315.pdf
It can be done, but at what cost and software will need to evolve to support all the cards on one OS, and the multitude of other reasons (like one motherboard dies and lots of hash goes down).
I already use the -wd 0 command in claymore and if I see the hash rate drop in the monitor, then I know a GPU needs some attention (overclocked too high or dead).

Some of you guys are already using a second power supply and should test (on the 12+ rigs) if the second PSU is shut off - does the miner continue hashing away, and just the GPU's attached to the turned off second power supply stop working, or does it take the whole miner down?  If not, then I think eventually we will see 4u rack enclosures with just the GPU's and power supply in each, with long USB 3 cables routed down the rack to the motherboard in the bottom 4u enclosure that has the motherboard and multiple pci-e switching cards.  To big for my budget, but something to envision.  

Edit - The card in the video is selling on Ebay for $125 US FYI - http://www.ebay.com/itm/142479750737

do you know name/model number of that board?

Asus B250 Mining Expert is the name of the model i think

That is a good name. This is right now the best mining board there is at moment, wonder when they will launch it.

they use plx chips to split the lanes. entirely doable.

heh, this is getting crazier day by day. But in other hand, market demand this kind of mobo, so Asus and Biostar build them.

Biostar only 12 slots and 1 psu. So meaning you need a psu adaptor, the asus can power 19 slots and has 3 psu connection, The asus way better than anything else.

I wonder how did they manage to get around the driver limitation of 8 GPUs per brand on Windows, if they even managed to do so. Linux is quite limited in overclocking/undervolting compared to Windows.

See that is the thing, we don't know if they achieved 19 gpus on windows.

Asus has not claimed 19 gpus to work on this motherboard. They claimed via Twitter 16 only, So I guess 8 amd and 8 nvidia. So I guess they are talking about Windows 10 limitation.

I wonder if this will cause a re-think in rig design. For 13 you can easily do the 2 level stagger but with 16+ I wonder if a circular case might be better.

Lots of pros and cons to this board. I'll wait to see how others make out. Troubleshooting an 8 card rig is already a pain.

This. Also I would like to know which miners work already with more than 8 GPUs.

That is crazy.  I can't wait for BitsBeTrippin to make a x19 1080 TI rig with that badboy.  Can you imagine trying to find your bad riser in that?

true, this 3x psu connector on the motherboard is quite "interesting" feature.

Check out the article guys, seems intresting,  the pcie slot detection  nice feature!

the pcie slot detection has been enabled in other Motherboards already.
