Hi guys today i'll show you which hardware's you need to build an 8 GPU ethereum mining rig with the best working graphics cards and motherboard available. Building GPU mining rigs with 6x graphics card are so old these days many people are trying to build rigs with 7, 8 or even 10 graphics cards, but there is some issues with 8 GPU rig, mostly motherboard not supporting 8 GPU but there are few like Asus Z270-A motherboard which we are using today.

So lets started building mining rig! Here's everything we need to build the rig,

Graphics Cards: Choosing best graphics cards are more difficult because mostly cards are out of stock or increasing huge prices in mean time so in below ill recommend few graphics cards which are working good with there mining speed and electricity consumes.

GeForce GTX 1070: AMD Radeon RX 480 and Radeon RX 580 graphics cards are sold out generally all around! we are all mining Ethereum on re-appropriated time and rather than waiting on AMD Radeon RX 480/580 cards to come into stock you might need to look around some other cards available. So I found GeForce GTX 1070 had really good hashrate producing with us indicating 27 mh/s of mining speed.
Radeon Rx 580: Producing 29 mh/s of mining speed and consume 135 watts of electricity.
Radeon Rx 480: Producing 27 mh/s of mining speed and consume 150 watts of electricity.
Radeon Rx 470: Producing 28 mh/s of mining speed and consume 140 watts of electricity.
Radeon R9 390: Producing 30 mh/s of mining speed and consume 250 watts of electricity.
Sapphire R9 290x: Producing 30 mh of mining speed and consume 290 watts of electricity.

Motherboard: Asus primes Z270-A motherboard which supported 8 GPU, this particular motherboard has 7x PCI-E slots and two M.2 slots for SSDs that can be converted to PCI-E connectors for additional video cards. You need PCI-Express adapter inserted to the one of M.2 slots so that will work with 8 gpu. There are some other motherboard are also available for 8 GPU mining, which are listed below.


Processor (CPU): We are using G3900 Skylake Celeron processor for this motherboard.

M.2 PCIe Extenders: As mention above, in this particular motherboard have 7 PCI-E slot we need PCI-Express extenders for M.2 slots, Than it will capable to run 8 GPU.

Power Supply: 2X EVGA 750 watts power supply + dual link cable, We are going to use 2x 750 watt power supple for this particular rig and single dual PSU link cable, so with this cable you will connect the two power supplies together with using the dual link cable.

Hard Drive: 128 GB SATA 3 SSD, This is for installing operating system and mining software, so this purpose we are using 128 GB SATA 3 SSD!

Ram: We have to only run mining software so we don't need high ram, 4 GB DDR4 Ram is enough for ethereum mining rig and i recommend to use Claymore Mining Software, it is simple and very easy to use.

RSIERS: These are use to connect multiple graphics cards to a motherboard by lifting them off and away from the motherboard. This will helps for more efficient cooling and increasing the life of the cards, as well as possibly running at higher speeds, you can get from here.

Windows 10:  We are using windows 10 operating system and you can download drivers from here:

Cooling Fans: For extra cooling we used Opolar Desktop USB Fan, it is cheap and big fan for our 8 GPU mining rig, it is easily available on amazon and you can buy this fan from just 15$.

Mining Rig Case: I'm always recommended to build your own case rather than purchasing! if you still want to purchase so buy Open Air Frame Case from here.

Note: What you need to make sure is to enable 4G Decoding in the BIOS of the motherboard so that the operating system can properly detect and work with all 8 video cards for mining.

That's it, GPU mining are more profitable these days so many people are banking with simple investment on hardware's. This ethereum mining rig surely generate more than 1400$ profits monthly after successfully assemble all parts.You can also mine other crypto currencies like zcash, monero, altcoin etc with this rig.
