How much Watt should my PSUs have? (Lets say for port A on the B250, with 7 x 1080ti)
How do you power up your GPUs? Do you connect power again to each riser card? or is it delivered through the sockets on the mainboard? Does the riser card channel the power from there? Maybe I got the concept wrong,
Your question is simple, if you put 7 of them on port A then 7 x 250w = 1750, minimum you would need is a 2000w superflower psu or a delta server psu 2400w, either way is fine. This board is great for high density mining.

I had the same problem, you will figure this out, And yes I am running SMOS from a Bootable usb stick, plugged into one of the USB 3.0 slots on the back, (you can try others) BUT, first make sure you wrote the bootable SMOS properly to the USB by powering off a laptop or some other computer, inserting the USB and starting the machine up, and see if Linux starts the boot sequence, if you know your USB is good, then, In your Bios of the B250 Mining expert, under the advanced tab you should find a BOOT tab at the top, under that, you need to turn off Fast Boot and make it regular boot, and then change from the EUFI Boot to Legacy, not the dual option, but the Legacy only, then save the BIOS changes and power off completely, before powering back on, as long as you have a bootable linux USB drive inserted, it should boot, if you mess up any settings, you can always short the BIOS pins on the mother board to bring it back to default, so no worries, and I did upgrade my Bios to the 12/15/2017 version via downloading it onto a completely different USB and flashing the Bios from within the BIOS,
Hopefully this helps, let me know, if it comes down to it, I guess I could go reboot my miner and take a picture of the actual Bios Boot screen settings,
Good Luck!
Cheers I'll give it a shot. Thanks for your help

I did not understand your question, the board consumes very little power, probably 10 - 50 watts or so per hour.

This is very impressive if it will accomodate different motherboard ports ranging from memory, hard drive, and power packs especially for the overwhelming windows users.

When I am calculating a proper sized PSU I have to include the boards need too... So (7 x 250) + 50 = 1800 - so PSU with 2000 Watt should be good anyway... I did not understand the riser thing: I support power to all the PCIe connectors via one main PSU, on A,B or C. When I connect the GPUs via riser do they pass on the power to the GPU? I have seen that the "normal" risers in any shop need their own uppowering,... what is the difference here and how does it work? Maybe I need a different riser or I am just asking too many questions and should not care? What about the power for the board itself?

Motherboard + CPU + RAM + SSD/HD will soak commonly 50-100 watt range depending on the details - more if you're using a high wattage CPU for some reason.
The power to the risers is for the power the GPU draws from the PCI-E bus, and is part of the total power draw of the GPU (plus a few watts for conversion inefficiency in the voltage conversion circuitry of the riser itself).

I remember when I had a i7 920, socket 1366, that wasted a lot of energy, just to turn it on without gpu was 150 watts.

go plug 14 amd on mining cards in the board.
IT DOESNT POST
go plug 14 nvidia non mining cards into the board.
IT DOESNT POST
whats so hard to understand? the board is flawed, and asus said they will fix this issue in a bios update q4 december 2017... this has nothing to do with amd or nvidia drivers. YOU CANT EVEN LOAD INTO THE OS.
Correct! 13x1080ti - working. 14< - doesnt post

It'll be pulling more once you put GPUs in and have the CPU actually doing some work - but not likely to be a ton more, that's a low-power CPU and most mining software doesn't put a high load on the CPU. Do keep in mind that a system at "idle" often turns the CPU clocks down a lot for power savings...

And you must leave those features to save power on if you are not using your cpu for mining.

What is your power consumption on the wall? How many and how much power do you have on the PSUs? go plug 14 amd on mining cards in the board.

go plug 14 nvidia non mining cards into the board.

Do keep in mind that a system at "idle" often turns the CPU clocks down a lot for power savings... g4400 is a 54W TDP chip. unless you're CPU-mining, it'll float around 10-15W tops while the GPUs do the work. Its almost negligble

Hy Casha, How is that working, the 1080 ti is announced with 320 Watt each...? 320 x 13 = 4000+ 3 x 850 is for the board? 1 x 600 for the risers? Did you see the video from invictus mining on youtube? I dont know if I understood this right... he is running only to PSUs on the board and try to take off even one of it...? Here is the link: https://www.youtube.com/watch?v=7Y_ICdwoZrsWhat is your power consumption on the wall?

I picked up this garbage board for overpriced 400 something to try and replace my btc pro 13 that died after a week mining...
Big mistake.
The board is finicky and garbage at the moment.
Right now my board endlessly resets itself every 5 sec after power unless you reset the CMOS via jumper. If I do that it gets to the mining pcie screen then resets and goes back to the reset loop.
Lovely. Can’t even get into bios settings can hit the pause button though n it will hang there until I press resume n it resets. Any idea what the heck is wrong??
The onboard hdmi does nothing no picture. I get usb 3.0 riser picture if CMOS is reset once but not after going into reset loop.
It started doing this when I set pcie speeds both to auto as it was not recognizing one of my cards in Linux but was showing green on boot!!
It has also frozen up in bios setup for no reason, fails to detect all cards (6), or goes into this crap reset itself endless loop!!! Can’t even get to setup or post.
I thought maybe it is because usb3.0 risers? Any ideas to fix?? What a piece of crap board my btc pro worked instantly with 13 cards but something died after mining a week n usbs stopped working
Nice..... about to just set up some 6 to 8 rigs and throw this garbage in a burn pit. What a nightmare!

Did you try to boot up with no GPUs installed on just integrated graphics?
Then if that works try to adjust bios settings or maybe update bios.

Yes, just try to boot only with igpu. It is looks like that there is something wrong with risers or psu. What happend to the last board?
