With 6 GPU mining Ethereum solo-mining and following my recommendations (the video will soon be online):
– Maximum theoretical power consumption : ± 750W/h.
– Hash rate max.: ± 181,8 MH/s.

For this rig I recommend you take the material below:

• The motherboard Biostar TB250-BTC;
• The Intel Celeron G3930 processor comes with a fan and pre-applied thermal paste;
• A power supply of 1200 W;
• 4 Go of RAM;
• A hard disc SSD of 120 Go;
• A pack of six risers, plan a few more (spare), just in case;
• Optionally you can take a support/case, the advantage of the one I propose is that it is stackable;
• Two pre-wired buttons, one for ON / OFF and you need one for the Reset;
• PCB supports for your motherboard;
• Thermal paste in case you have a problem with the thermal paste pre-applied on the fan of the processor;
• And finally, the most important, the graphic cards. I recommend starting with 3 or 4.

Theoretically this motherboard supports 13 GPUs, but if you introduce a GPU into the PCI-E x16 port of the motherboard, it will be difficult to connect the riser just next door. To avoid damaging our hardware, I not recommend to use this PCI-E x16 port and therefore to be satisfied with 12 GPUs.

With 12 GPU mining Ethereum solo-mining and following my recommendations (the video will soon be online):
– Maximum power consumption: ± 1450W/h.
– Hash rate max.: ± 363,6 MH/s.

For this rig I recommend you take the material below:

• • The motherboard Asrock H110 Pro BTC+;
  • The Intel Celeron G3930 processor comes with a fan and pre-applied thermal paste;
  • Two power supplies of 1200 W (one power supply supports 6 GPU);
  • If you take two power supplies, you will need a “Multiple Power Supply Adapter” * (see note below);
  • 4 Go of RAM;
  • A hard disc SSD of 120 Go;
  • Two pack of six risers. Plan some spare risers (one riser per GPU + reserve in case of breakdown);
  • Optionally you can take a support/case, the advantage of the one that I propose is that it is superimposable (this support supports 14 GPU);
  • PCB supports for your motherboard;
  • Thermal paste in case you have a problem with the thermal paste pre-applied on the processor fan;
  • And lastly, the most important, the graphic cards, 12 if you are not cold, unless you want to start “Easy” 🙂

Note*: If you plan to have more than 6 GPUs, you will need a second power supply and a “Multiple Power Supply Adapter”. The first power supply will power 6 of your GPUs, 6 risers and the components of the computer (motherboard, hard drive, etc.). The other power supply, it will be provided for the power supply of the 6 other GPUs and their risers. The 2nd power supply will not be connected to the ATX port of a motherboard, the “Multiple Power Supply Adapter” is needed to simulate the presence of a motherboard and ensure that your 2nd power supply feeds your other 6 GPUs only when the rig is on.

Attention, important detail, the “Multiple Power Supply Adapter” must be connected as follows: The SATA connector of the adapter must be connected to a SATA cable of the 1st power supply, and the ATX connector of the adapter must be connected to the ATX cable of the 2nd power supply.
