If you have followed out previous post of buying your mining rig hardware and it has now arrived then you are ready to get started with the build.

If you missed the last post, check it out:  1. Equipment and parts –  GPU mining guide.

So if you bought everything from the previous post then you should have the following parts:

  1. Motherboard with 6 PCI Express slots.
  2. CPU.
  3. 4-8GB RAM.
  4. PSU – 1200 Watts
  5. 120 GB  Solid State Drive.
  6.  Rig frame.
  7. Case Fans X 4.
  8. 6 X PCIE Risers.
  9. Graphics Cards X 6.
  10. Power Switch.

So if you do then great. The only things we are going to need to put this together is a small Phillips screwdriver and some patience.

1. Build your rig frame

Firstly, build your rig frame. Simple as. Once you have put it all together you should have something similar to this, depending on the one you purchased. You should take note of the screw hole locations on the base of the frame as this is where are motherboard will go in step two.

2. Put your in your Motherboard

The holes on the base of the rig should align closely if not perfectly to the screw holes on your motherboard. The motherboard and or rig may have come with screws. Attach the motherboard and place the screws into each slot. Loosely tighten all screws first and then individually tighten them all.

3. Add your CPU

Your CPU should come with some Thermal Paste already added to to its surface, this is a sufficient amount. If your CPU does not have thermal paste already applied, then you can pick some up for a few dollars on amazon. Intel processors come with a stock CPU cooling fan, this is perfectly fine for mining. Before opening the CPU ensure it is the correct socket for your motherboard, it will likely be LGA 1150 or LGA 1151. If its not, send back to the supplier and order a new one. Once your happy that its the correct socket go ahead and carefully place the CPU into the socket.

  • Lift the CPU case arm, removing the plastic placeholder and carefully place the CPU into the slot.
  • Try not to touch the surface of CPU as grease and oils from hands can damage the CPU.
  • Close the arm from the CPU case and attach the stock fan.
  • Your CPU Stock fan should also connect to the CPU Fan connector.

 

4. Add your RAM

Your Motherboard may differ

Go ahead and add the RAM and plug your RAM in to the slots available. You should have at least 4 GB of RAM but we recommend 8 GB as per our previous post.

  • When connecting the RAM there are two slots available, each with a small clip on the end.
  • Push the clip away from the main section of the RAM slot.
  • Ensure you have the RAM facing the right way, you should notice a small divider inside the slot, align your RAM stick to this divider.
  • Place the RAM stick lightly inside until you hear a small click noise.
  • Fasten the clip on the end of the RAM slot to secure it.

 

5. Attach your PSU – but don’t plug it in!

It’s a good time to screw in the PSU but there is no need to attach any cables yet or plug it in. The first thing you will want to do is just attach it to the rig frame. Align up your PSU and attach loosely screw it to attach, once both screws are loosely screwed in, you can go ahead and tighten them.

 

6. Attach the Cables

  • Attach the 26 Pin motherboard cable 1A in the below to 1B on the motherboard.
  • Attach the CPU power cable in 2A to 2B on the motherboard. The CPU power cable itself should have CPU written on it.
  • Attach a 6 pin power cable to 4 Molex to the Perif 1 slot on the PSU in 3A to 3B.

7. Attach your graphics cards

Connect the Power cables from the VGA Slots on the power supply unit to the slots on the graphics card as shown in 4A & 4B. Your PSU should have 8 + 6 pin power slots. Connect the SATA to Molex to the PCIE Riser as seen in 5A to 5B. Once the PCIE riser is connected to the power supply, connect the PCIE USB riser to the motherboard 6A to 6B. Ensure you are connecting the riser the correct way. Once the riser is connected, you can place your GPU in the Riser slot in 7A to 7B. The riser slot has a clip at the end which should be unfastened by pushing away from the riser before placing the GPU in the slot. Failure to do so may result in damage occurring to your PCIE riser or worse your GPU.

You should attach either by screw or cable tie- each pcie riser and GPU securely to the frame of your rig. There are 4 screw slots on the PCIE riser for this purpose.

 

8. Attach the SSD

Your motherboard, SATA, PSU and SSD may vary.

Connect the SATA 3 cable in 8A, which should come with the SSD to the SSD connection at 8B. Attach one of the SATA cables which are connected to the PSU from 9A to 9B. Finally connect 10A to one of the SATA slots on the motherboard in 10B. Ensure the SSD is laying flat and is secured to the rig. A cable tie will satisfy securing the SSD.

9. Quick Recap. 

So far we have

  • Assembled the case
  • Attached the motherboard
  • Added the CPU & fan
  • Added the RAM
  • Connected power cables from the PSU to
    • The Motherboard
    • CPU & Fan
    • Molex slots
    • Connected the PCIE Risers
    • Connected the GPUs to the risers
    • Connected the PSU to the Risers and GPUS
  • Added the SSD

Your mining rig should start looking something like this:

We are nearly there now, we just have three more things left to do to finish building our first GPU Mining Rig.

10. GPU Mining Rig – Wire Management

It is extremely important to ensure your wires are not a cluster of wires leading off in every direction. This can block essential airflow and can melt the wires if they are exposed to intense heat of the GPUs over time. Use cable ties to tie the wires from the PSU around the frame of the rig to allow maximum airflow.

11. Connect the Case fans to the rig frame

Go ahead and either screw or cable tie the case fans to the appropriate holes already screwed into the frame. Each fan should have either a 3 or 4 pin connector. As there is four case fans and only one fan connector you will need to ensure you have already picked up a multi-case fan connector. This will allow you to connect multiple fans to a single fan plug. Connect this multi case fan connector to the 3 or 4 pin fan slot on the motherboard.

12. Connect the power switches

You will need to add the two power switches to the motherboard. Otherwise how on earth do you expect to turn it on. Each power switch will need to be connected to the appropriate power connector on your motherboard. The power switches have a positive and negative pin slot. The positive slot is typically indicated by an arrow or other symbol. The power connected should be connected positive to positive, and negative to negative. You should follow the instructions in the manual which comes with your motherboard to ensure you have connected to the correct slot and do the same for the restart button.

Once these are connected, go ahead and plug in the PSU to the wall socket and do a final check to make sure everything is connected properly and no sockets are loose.

13. The grand finale

Press the power button and hopefully your rig should turn on and you will see the motherboard BIOS settings.

The next post will follow soon on installing your OS.
