Building a 6 GPU Ethereum mining rig
is a rewarding project. Here in this guide, we will walk you through selecting
the best Ethereum mining hardware, assembling the parts, and
configuring the software to get your very own Ethereum mining rig up and
running. It should take you about three
hours to assemble this mining rig. At the time this post was updated (7/6/2017) this mining rig should generate over $800/mo in Ethereum cryptocurrency. You can see the current mining profitability using this handy calculator.

Sidenote: If mining isn’t your
thing, and you are just interested in purchasing some cryptocurrency as part of
your investment portfolio, I personally use and recommend Coinbase (they give you $10 when you use that
link to purchase your first $100 of Bitcoin). I would also recommend keeping
your coins safe using the Ledger Nano S hardware wallet, since even the best crypto exchanges can be hacked through
a variety of methods. OK, with that out of the way, onward to the build guide…

GPU Ethereum Mining Hardware Build List
Listed below is the hardware you
will need to purchase and assemble. Basically, you are building a custom
open-frame PC, but instead of one or two graphics cards (as you would find in a
gaming computer), you will be adding SIX to the build requiring riser cables
and a frame as shown in the photo.
Quick Build List:
- 1x 1200 Watt Power Supply
- 1x 6 GPU Motherboard
- 1x Skylake Dual Core CPU
- 1x 4 GB RAM (system memory)
- 6x Nvidia GTX 1070 GPU’s (6 of these, I like EVGA and Gigabyte)
- 1x USB Riser Cables (6 pack)
- 1x Solid State Drive (for OS / mining software)
- 1x Open Air 6 GPU Mining Case
- Eth OS or Windows 10 (depending on your preference and setup)
- Monitor, Mouse and Keyboard (only needed for setup)
A more detailed explanation of each
component continues below:
Power Supply
– 1200 Watt Power Supply – The key here is to
have an efficient 1200 watt modular power supply that will save you over the
long run in electricity costs. Look for Gold or Platinum rated (as opposed to
silver or bronze). This is the industry standard for rating the efficiency of a
computer’s power supply unit (PSU).
Motherboard/CPU Combination – What is the best motherboard for mining Ethereum?
I’ve listed below my favorite motherboard and processor combo that is
compatible with 6 video cards. This is the ethereum mining motherboard that is
used in large scale mining deployments. If the pros use it, you know it’s good.
6x Graphics Cards (GPUs)
– Nvidia GTX 1070 GPU’s – The
very efficient Nvidia GTX 1070 can produce 30Mh/s using only 100 watts of
electricity. It is much more power efficient than the other GPU’s in this list.
Anyd of the twin fan overclocked Gigabyte or EVGA cards work great out of the
box.
RAM (System Memory) – 4 GB RAM – You don’t need a lot of system
memory to mine ethereum effectively. 4GB is about as small as a stick of RAM
comes these days, so I recommend just picking up a cheap one for about $20.
USB Riser Cables – (6 pack) USB Riser Cables –
These are to connect the 6 graphics cards to the motherboard and allow spacing
between cards for heat dissipation. These are necessary when building a rig
with this many GPU’s.
1x Custom Mining Case – I’d recommend an Open Air 6 GPU Mining Case like this or this. I’ve built several of these 6
GPU rigs for family and friends using this particular case model.
Operating System – Eth OS ethOS is a free 64-bit linux OS that mines Ethereum, Zcash,
Monero, and other GPU-minable coins. If you are using the Nvidia 1070 GPU’s I
recommend mining on Windows 10,
since Eth OS has some driver issues with Nvidia cards.
Assembling
the Custom Ethereum Mining Hardware
- Un-package everything
- Build / assemble Open Air 6 GPU Mining Case
- Install processor and RAM on motherboard
- Plug in all riser cables
- Place motherboard in custom open air mining rig case and connect motherboard PSU connector (leaving PSU unplugged from the wall of course)
- Plug in SATA hard drive (or optional Linux on USB stick)
- Connect all GPUs to riser cables and fasten them to custom case. You might need to experiment for optimal spacing to keep the cards cool.
- Plug in all power supply connections.
- Connect mouse, monitor and keyboard and an internet connection (I use a USB WiFi adapter)
- Check all connections once more
- Fire it up! Install ETH OS.
- Make sure fans are fully functional. Start the mining software, tweak settings for maximum hash rates and let it run!
Congratulations! You are now the
proud operator of your very own custom built 6 GPU ethereum mining rig.
