Octominer B8PLUS 8 PCIe Slot Mining Board (Motherboard, integrated CPU)

Small update.
We are accepting Credit Card payments now through Stripe Payments!

Okay I will buy one then.  Just a mobo.
I have a question  has anyone done 8x 1080tis  on this board?

Yes, many clients are running 1080ti's already. Temps stay around 65-68C if using inside our case with Delta fans.

Your case is not needed   I use waterblocks.

This is my 8 1080ti build

I can run  on a different mobo  but I am forced to use an ATX psu  and none are big enough. For me to run eight at 200 watts each.


I want to try your mobo.  My guess is it will suffer due to the low priced weak cpu you put in it.

I will run it in smos and compare it to this  mobo


I am not knocking your mobo  as it will allow me to use the 2400 watt delta  server psu  and that is a big plus.

I am knocking the weak cpu option only.
It truly would be nice if  it could have a better cpu as an option for power builds like I will do.
I will have 3 different 8x 1080ti builds on 3 different mobos  two will be using the 2400 watt delta psu (no longer available)
My first  8 slot builds  on 2 other mobos  both have flaws.

One  needs an atx  and there are no 2400 watt atx psu's  it also needs 1 short 1080ti
One has heat issues and can not run  8 cards via the pass through design it uses

both allow good cpus.


yours  looks to be good in every way but weak cpu.  I will test it out  when it arrives

Thanks for the feedback but so far nobody has complained about the CPU performance. People are happy about the low voltage and efficiency of the CPU. We already have professional miners using our boards that have 1000+ GPU farms. We had the intel 4415U CPU version also that we sold, but it was limited quantity only.

Your waterblock setup looks pretty sweet! I actually plan to build a test system with 8x 1080TI also with waterblocks.

can't charge
let me know when you fix it

Can someone please give me their amazon affiliate link of what yellow splitter cables I need to connect Evga 1200w P2 to 8 p106-090? I’ll order lots other stuff too - thanks!

Would I need 6 or 8 pin to 2x 6+2 pin and how many?

Hi OctoMiner,


I am looking forward to build a prototype out of your blocks in germany.

My experience:

Ordered 3 motherboards, 3 ram, and 3 server PSUs. Motherboards and ram were flawless. Installation was insanely easy. Literal plug and play save for a few bios modifications.

However - server PSUs have been nothing short of a nightmare. First PSU flashed a bright white on startup and didn't turn on again. Second PSU worked and I managed to mine equihash on HiveOS. But then I heard a loud SNAP, and found the PSU dead smelling of burnt plastic and hot to the touch. Tried the third PSU after, but it never even turned on. There is nothing abnormal about my house and I already had two rigs going.

Customer support has been nothing short of outstanding though and I have heard nothing but good things about Octominer. I think they just have a bad batch of Server PSUs that are either manufactured cheaply or have poor quality control. That would explain how their price is so low. Will be looking to get a refund for all of mine.

Yes, we had a problem with the server PSU. The factory that makes them for us made a big mistake, they have 2 versions. 1 version only works with 220V , the other version works both 110/220V, they mixed up some of the PSU and some % of the PSU that is supposed to be dual voltage 220/110V is actually just 220V. We are really mad about this with our PSU manufacturer and we are solving the problem at the moment. Don't worry though, it's just a fraction of the PSU and if your server PSU is running, it should keep running for a long time. Also the PSUs have protection circuitry inside, there is no way they can damage the GPUs.
We already have professional miners using our boards and server PSUS hat have 1000+ GPU farms and they are extremely satisfied with our products.

We 100% honor our warranty and if anybody has any issues, please contact us right away on Live chat or email and we will refund your order and send you a return shipping label for the defective PSU.

Thanks to everybody who has supported us and sorry about this issue!

I see the atx psu is back in the shop. Is it safe to assume that it'll be in stock to ship with the early March batch of boards?

I ordered 2 server PSU's yesterday - how would I know which versions I get?

This problem only affected a fraction of the PSU sent out in February. All new orders made for the March batch will be unaffected.

There is a reason proper/real/genuine server psu`s have two letters on them - HP Do not buy Chinese junk. They are not real server psu`s, Chinese clones of HP products. Only buy real HP stuff, which will last you years to come and won`t risk your expensive gpu`s.

@octominer I have a reliable electronics manufacturer (with strong R&D) that I recommend you use. They can manufacture the motherboards and PSU for you.

You can PM me if you want more info.

Our PSU's are solid also and we stand by our product quality.  Just an unfortunate mistake that happened.
The problem with the HP PSUs is that the breakout board quality can be really bad sometimes, I have seen photos where the breakout boards from parallelminer come with many defective and shorted solder points.

Ordered one of their cases and an ssd for my board. Still waiting for it to ship. Hopefully it goes out today/tomorrow.

Hello @philipma1957


I hope they do a testing with Intel® Core™ i7-8650U Processor very soon,
seems to be the fastest for this board.
