24w for a g4400, 8gb corsair VENGEANCE!!! 2400mhz stick, asus b250 mining EXPERT!, one sandisk 120gb ssd, and windows 10 doing nothing but in desktop. using an evga QC 1000watt gold

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...

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

What is your power consumption on the wall?

How many and how much power do you have on the PSUs?

PSU 3x850 1x600
13x1080ti ~2500w

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.

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

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.

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).

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... Wink

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? Wink

What about the power for the board itself?

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.

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

Hy Alyeska,

did I got you right, that you supply the risers itself from the PSUs?
Arent the sockets supplied from directly from the PSU?

What us the necessary best power rate (Watt) for the PSUs connected? I couldnt find anything about

What kind of "wifi smart plug" are you using there?

SMOS can report on the phone? via internet or SMS?

Does SMOS work with NVIDIA 1080 ti?

sorry my questions must sound dumb...

Good night

Same - I am currently powering 9 GTX 1070ti SC Hybrids off of one EVGA 1600 t2 Power supply with an at wall outlet power draw of 1370 watts On my Asus B250 Mining Expert running SMOS with overclocking settings of core/200 memory/1400 and my Watts to 136

and after running for 48 hours of solid up time, I am happy to report that I am getting

========== Sol/s: 4762.0 Sol/W: 3.92 Avg: 4776.0 I/s: 2557.4 Sh: 41.18 0.99 211

THAT'S 529 Sol/w at only 136 watt per card! Perfectly stable on the Asus B250 Mining Expert running SMOS

-------------
I have more cards and Power supplies on the way, and will update if I can get 12 1070ti running soon under SMOS
-------------

I set up the Bios to boot from power restore, and have a wifi smart plug to reboot the machine if I need to remotely, for instance Yesterday I switched the Algorithm I was mining on the fly, while I was not at home yesterday,(actually 40 miles from home) and SMOS hung, so I successfully rebooted remotely (via the wifi smart plug), And SMOS rebooted and happily started reporting into the web interface on my phone that it was mining away at full hash power on the new Algorithm,

I currently really like this board, and believe that Asus will at some point follow through on allowing us to post up with any 19 cards, so I already have purchased two additional B250 Mining Experts, and will began building them out, once I max this first one to it's current potential, which may be 13 cards until an update.

Some notes: I have none of the AUX molex plugged in, those are for people that are not using Powered Riser cards I have been lead to believe, I only have one power supply plugged in, but have my working 9 cards spread out over 2 of the 3 card banks no problem, once again, because the slots work fine if you are supplying the Power via risers (as in the you don't need three power supplies for this board, you could use one, then a Server PSU to power cards etc...

I am still learning more about this board every day , but so far like it, Love the Post screen showing which GPU's are seen at boot up, and which slots, coupled along with Risers that have an LED on them, I feel this will greatly enhance any future trouble shooting to find a bad card, USB cable, Powered Riser, Etc...

Yes SMOS will work with a 1080ti,

all power supplies have different wattage's and qualities IE: GOLD - up to Titanium and can be used to different potentials, plus you need to take into account the outlets breaker and staying below 80% utilization, so on 110 volt 20 Amp circuit breaker outlet, you should not use more than 1920 watts, or you will blow breakers, just an example, your wiring may be different voltage and Amperage, you need to tailor this to your situation,

I look UP SMOS on my phone via Google Chrome, and stay logged in so that I can administer my miner from anywhere,
https://simplemining.net/

the smart plug I use is this one, it allows me to know a lot about the miner attached, it's up time, current wattage draw, and allows me to turn it on and off again from any where in the world I have an internet or phone connection,

There is NO logical reason for it to be limited to 13 "standard" cards - and it's NOT a drivers issue, it's a BIOS limitation issue on the part of ASUS.

Well AMD never stated more than 12 gpu's. So we can't really say its asus.

It's an ASUS isssue - they're not saying "max 13 regular cards from one vendor", they are saying "max 13 regular cards PERIOD".
If you mix AMD and NVidia, there is no reason you can't have 8 of EACH with the normal drivers that were available for WINDOWS at the time of the release of this board.
LINUX at the time didn't have even THAT much of a limit.

There is ZERO rational reason to require P106/P104 mining-specific cards to be able to run more than 13 cards from this board.

There is also the question of the AMD "mining" cards that do not have a video output like some of the Sapphire models and if those are counted as "mining cards" by the ASUS bios.

not only P106, it works fine with P104 mining cards too.
I guess this 13 GPUs limitation is somehow related to count of GPUs with display outputs.

Yeah, you might be right about that.

This board was gimped by design in REQUIRING Nvidia P106 mining cards for over 13 cards. Asus should have made clear the requirements instead of posting ambigous charts that left it up to interpretation. The fact that the board can boot and mine with 13 AMD cards as long as you run P106 mining cards as well shows that the limitation is by design with a a Bios check for the mining cards on POST. Something that should be EASY for Asus to remove or give an option to bypass if they chose to do it. In other words don't hold your breath waiting on Asus.
