The motherboard has three ATX 24-pin connectors to directly connect a PSU, one for each bank. No adapters or cables are needed to link the PSU's

I'm not sure if Asus did something to totally block secondary alliance of power, cause if your house has 3 phases and you connect 2 different power sources in the motherboard then you might fry everything.

I’ve connected 3 ATX 24 pin power, 8pin EATX (near processor) and 3 AUXPWR (in the side of PCI slots). Upon power on, two other PSU fans are running but main PSU where I connected AUXPWR and EATX is either not working, not even the PSU fan. If I remove the AUXPWR and EATX, the PSU fan stays working but offcouse MOBO is not powered on. What am I doing wrong here? Any suggestion ?

Hi, you need to power all 3 molexes and 8pin cpu from the same psu, which is connected to atx connector number one.

You could visit the official site of Asus B250 mining Expert for some references: https://www.asus.com/Motherboards/B250-MINING-EXPERT/Just make it as the guide from Asus: if you plan to install 13 GPUs, with lane A & B, just plug all risers in A01 - A06 and B07 - B12. If more than 13 GPUs, it means you need to use lane C, in the case you have 2 PSUs which could power all your GPUs, use add2psu for lane C. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FmRoA6JF.png&t=663&c=jmTqX0P9MLVnGw)

Ok. I’m restarting everything. No GPU to start with. Just MOBO, processor, RAM and I should get the bios screen. One psu with 24pin atx, 8 pin EATX. No power up. This is driving me nuts. Haha
My other rigs are with ASRock BTC H 110 with 8 GPU rig.

You need to plug 24pin atx, 8pin eatx and all 3x molexes to run. And if it´s not help, just try to reset bios. If it´s not help. You definetly have something wrong with PSU or mobo...

I’m using 2 silver stone psu and 1 cooler mater psu. Somehow I mixed up the wires and I used cooled masters 8pin EATX with silver stone. This is why when I unplugged 8pin EATX the psu fan started worked. All started working fine when used the wires correctly in their native psu. My rig is now up n running, cheers!
So lesson learned: don’t mix up cables in diffident PSUs.
Thanks for those who tried to help me, cheers !!

Bought about a week ago in Singapore. I’ve paid SGD 220 which is about USD 160. It shows PCI slot status during not up whether it’s working or not.

Ok, my next set of challenges in B250 lol
1. How to set up “power on bootup” in this MOBO? 2. How to turn of on-board graphics
Spent some time searching bios option and options seems hidden from my eyes lol

You have mentioned few times that to keep the memory cool. Are you referring to the RAM or is it the one that you have circled in Red in below image ? ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2Fr0tx9Fh.jpg&t=663&c=eVUzSgKPykQzNQ)

This component inside the red circle became very hot. The best way is to use some small pasive heatsink 8x8mm is more than enough. I am not sure what exactly this chip is, but I think that it is something for pcie slots communication...

Memory temp of the Vega
as gaming puts weight on the vegas cpu the temp you see in wattman and ntool is cpu temp not memory temp which can be 20C higher, because mining and especialy cruptonight puts weight on the vega memory modules
you can use GPUZ to see memory temp, but make sure you run it first before you start the miner (as its a bit heavy for the system to load), and then see your mem temp compared to cpu temp seen on the miner waterfall and wattman and ntool
adjust environment and fan speeds to keep mem temp well below 80C (i like the 50's), gives your cards a longer life too
thnx for the wishes
merry xmas and happy new year

to mine or not to mine, is not a question...

Yea sure, will do that. Thanks for the reply and tips. I noticed chip is there on the other motherboards as well, like ASTOCK H110 BTC. So the heat problem is only for ASUS B250 motherboard only or is it just a command good practice to keep that component cool?

Ok, I used GPU-Z only to check whether I got Samsung memory or Hynix memory lol. I check the GPU temp from the afterburner or miner log but never knew that we need to check and control memeory temp. Good information. Thanks.
