that's fine per Rig 6 GPU i will do that
but do i need to buy new PSU or buy new PC mobo + ram + PSU?
Total 12 GPU
first rig 6 GPU
second Rig 6 GPU
Or buy new PSU for my Motherboard ?
Personally, I'm not a fan of mining rigs with more than 6 GPUs using risers, but since you are staring, you could just use the motherboard you have with one more PSU until you learn all you want to learn and decide what to do going forward
Yep i guess how . i have now Asus mining mobo
but have question here ,
Example
My power supply A will use it to power ALL my x7 Riser by pcie cable
and my power supply B For all my GPU's x7.
So Rosewell power supply for the Risers
Evga power supply for GPU's
have issues here ?
