Ethereum Mining Rig List, Prices and Profit

Mining Rig Equipment List Pricing

$138 Motherboard
$269 Power Supply
$43 RAM
$36 Processor
$39 EthOS
$3 Power Button
$49 GPU Risers

GPUs = $1,560

$260 / GPU = $1,560 for 6

Optional Items = $97

$13 Cooling Fans
$6 Thermal Compound
$7 Sata Cables
$41 Wireless Adapter
$18 Voltage Meter
$12 8Pin Power Cable

TOTAL = $2,224 for a 160 MH/s Miner 6 GPU

160 MH/s will earn you about 0.012 ETH / Day ~ $8.25 (with ETH at $715)
This will take you 269 Days of mining to break even

But you need to factor in that this rig will run you about $3/day in electric so more like 425 days to break even.

If you go for 12 GPUs at a total cost of $3,884 for $16.50 / day – $6 /day electric that will take

375 days to break even


18 GPUs at a total cost of $5,644, $24.75 / day – $9 / day =

350 days to break even. This is due to the additional Power Supplies required


I really like this 19GPU Asus motherboard. I have yet to get the 19th slot to work (it’s the full length SATA slot) and it can be tricky at first to setup if you’re using a lot of different GPU’s. I will do another post on configuring this motherboard.



Power Supply

The ASUS Motherboard supports up to 3 power supplies, depending on how many GPUs you start out with you can start with just one and add more later. If you have 6 GPUs on one power supply you will want to get the 1000W or 1200W, I started out with an 850W and 4 GPUs then purchased a 1000W and then a 1200W. The 850W is technically enough to run 6 GPUs (as most pull around 105-130W) but the 1200W has a higher efficiency.

EVGA 850 W Platinum Power Supply $199.89 Amazon

You just need one 4GB Module of DDR4 RAM. Mining uses the GPU RAM.




The great thing about GPU mining is the minimal CPU requirements. You can literally run the rig using the slowest Celeron processor on the market.




This is the operating system specially designed for mining Ethereum. It can run on a USB stick so you don’t have to purchase a hard drive. You will need to make the USB a bootable USB to load EthOS (don’t just drop the file onto the USB).



Power Button

I had no idea the motherboard needed a power button. I almost sent it back thinking it was dead then realized it just needed a power button.



GPU Risers
There are several different GPU riser types. I like these because they have the 4Pin power plug on the side facing up. This makes it way easier when you chain 3 or 4 GPUs on the same power cable. These also have an LED light that lets you know it’s plugged in. If you find yourself running out certain power cables these have a plug for 4Pin, Sata, and 6Pin.



Cooling Fan

I was skeptical how effective little fans like this could be, but my GPUs were running hot and I had a big fan blowing on them. I purchased 3 packs of these (6 total) and placed them next to the GPU (blowing air away from the GPU) and amazingly it lowered the temps by 4-6 degrees, enough to lower the GPU fan and increase the GPU power efficiency. Final verdict, these little guys are actually worth their price. They’re available in 7 different colors.

$13.99 / 2 Pack


Thermal Heatsink Compound

You won’t need this the first time you attach your CPU to the motherboard. I upgraded motherboards and swapped the CPU so I needed to use this.



Sata to 6Pin Power Cable

These are really handy when stringing your GPU risers on the same power cable otherwise you’ll need to use a single SATA cable per GPU.

$7.49 / 6 Pack


Wireless Adapter

EthOS doesn’t support wifi so unless you want to run an ethernet cable to your rig you can get one of these guys to go wireless.



Voltage Meter

This is handy when you’re overclocking to determine the most efficient power settings. Optional but important if you really care about power use.



8Pin Dual GPU Power Cable

This lets you split a single GPU power cable and power 2 GPUs meaning fewer power cables needed.



MSI Radeon RX 570 4GB 0.11 MH/s PER 1$

This is the best card I have purchased so far, I was able to buy 4 used ones on eBay for $260 per card. They came with a BIOS mod that runs them at up to 29 MH/s

$260 – $450


ASUS Mining RX 470 4GB 0.05 MH/s PER 1$

I purchased 4 of these off Amazon at various prices ranging from $350-$450. I believe there are BIOS mods that up the hash rate but I haven’t flashed any of my card’s yet. It runs stock at around 23 MH/s. This was another example of getting the same card with 2 different BIOS versions, one is a Ellesmere RX 570 the other a 470. The both has at pretty much the same rate though.)



Gigabyte Radeon RX 560 4GB 0.07 MH/s PER 1$

I purchased 2 of these from and I’m not sure if NewEgg is selling used GPUs but they came with different BIOS versions and hash at 2 different speeds. One hashes at 12.5 MH/s and the other at 10.5 MH/s
