Building your Rig – Cabling
This post is part of a dummies guide to building a 6 GPU crypto currency mining rig. If you followed part 2 you should have the main hardware for your mining rig installed, with one graphics card connected. Now we need to connect up all of your components with the Motherboard and PSU.
First you need to connect your PSU to your motherboard. You will probably need to connect up two power cables. If you are using the Gigabyte GA-H110 you will need to connect an ATX 24-pin and an EPS 8-pin from the PSU to the motherboard. If you have any doubts check the instructions for your motherboard.
If you have purchased a dedicated crypto currency mining board the manufacturer may also suggest connecting additional 4 pin molex cables to add extra power to the pci-e slots.
As we will be using USB powered risers to power your cards you do not need to connect these.
Hard Drive Power and Connection
Next connect one of your SATA power cables from your PSU to your hard drive. You will also need to connect your hard drive directly to your motherboard with a separate SATA data cable.
The power cable should be provided with your PSU and SATA data cable with your motherboard.
Power and Reset Switch
Check your motherboard instructions and it should show you exactly where to connect your power and reset switch. You can also connect the hard drive and power led lights if you want.
The motherboard and cable connections should have positive and negative markings which you can line up to make sure you have them the right way round.
For now leave the on/off and reset end of the cables loose.
Take one of your pci-e power cables and connect the cable from your PSU to your 8-pin GPU slot. I am using a Power Color Radeon RX580 card which has an 8 pin and 6 pin socket. We only need to connect up the 8 pin.
Connect the USB PCI-E Riser
I’m going to do a separate guide on how to connect all six risers up correctly, but as we are only using one riser to test everything out, it is fairly straight forward.
You should have either a 4 pin molex connection on your riser like this:
Or a 6 pin connection like this:-
If you have a 4 pin molex simply connect it directly to one of the molex power cables from your PSU. If you are using a 6 pin PCI-E riser, then for now connect it to a separate PCI-E modular power cable directly to the PSU.
Next you need to plug in the USB cable provided with the riser pack. It should look something like this:-
You can now plug your GPU into the riser. You need to open the catch and then push it up into the bottom of your card. It should go in fairly easily and does not need to be forced. Once in place fasten the clip to secure.
The other end of the USB cable should be connected to the small PCB that goes into your PCI-E slot on your motherboard. You can now slot this into one of your PCI-E slots as shown in the picture below.
Connect up your monitor and power cable e.t.c.
That’s all the cabling for the time being. You are now ready plug your monitor into your GPU and your PSU into the wall. You will also need to plug your mouse and keyboard into your motherboard ports.
Now you are all ready to power up your 6 gpu crypto currency mining rig for the first time. Please check out my next guide before booting up your rig!
