Topic: How to power this mobo for mining (Read 137 times)
It's indeed a Chinese motherboard but I've power it up running hive OS right now, another issue I'm facing is it only detect 5 GPUs if I try inserting a 6th GPU the motherboard will trip off and restart again
What is the name of this MOBO? Looks like those Chinese motherboards aka colorful and others that have no brand name, anyways they did their jobs right if you don't mess things up yourself, forget those slots since you will be using risers anyways, just connect risers and start mining
Reason why they put that there is so you don't pull the +12V power from the motherboard connector. So if you put the GPU inside the actual slot or use an extender ribbon (not a riser) then it'll need to pull +12V to power the GPU.
They do this on regular gaming motherboards also, usually there is an aux connector where you can connect a SATA or Molex connector. And what that does is if you got a SLI setup going then the +12V thats required to power the cards plus the memory, cpu, etc will need to pull the power from the motherboard connector and might overload that wire. Hence if you use aux power it'll pull less current and you don't need to worry about anything melting.

No you dont need because your risers are allready powered risers.
Thanks for replying @batsonxl so what's going to happen if I decide to power that slots? Will it feed all those pcie slots power? I mean if I'm using a riser that has no power, something like just normal pcie extender with no power
If you are using a full extender not riser (extender doenst have power connector) then you will need bus power. This is very hard on a mobo as multiple cards are not generally designed to get up to 75W each from mobo. This is why miners use Risers which have separate power connectors. Risers also dont pass power from mobo to riser/gpu.
Since you will need power from bus you will need to plug either a molex 4 pin or pcie6 pin into one of those two slots. As best as i can tell from the poorly done manual they are wired the same so either should work. I would us the 6pin as it allows more watts than the 4 pin.
In looking at this only gpu0 will have full power from mobo...the short slots should just use standard risers meaning they get a power plug each and dont use mobo power.
I would do the same for the long slot on gpu0 and then not worry about pcie power.

Guys please take a good look at the picture below and you will see where my green arrows are pointing, the thing is I don't know if I have to power those slots for the pcie slots to work or I don't need to power them at all? Or I just need one molex or just one 6pin inserted into the motherboard
