I know that this has been mentioned in many threads throughout our forum but I want to get specific with these mining topics. So let’s start with what you need to buy to build your own GPU mining rig.
I want to make this simple enough for people who haven’t built a computer before and are not familiar with what it takes to build a computer. Building a GPU mining rig is similar to building a computer. This is the first part of many threads to come. By the end, I hope that all of you will have the basic knowledge of how to build your own computer and mine cyrptocurrencies!
What do I need to buy to build my own GPU Mining Rig?
Open air Frame - Open air frames can be found all over the internet now. They range from wood structures, to acrylic, and even metal. You can even find YouTube videos on how to make one yourself. Some of these frames are even stackable which is really nice when you have limited space. An alternative to an open air frame structure is a wire frame rack that you can purchase at Home Depot. The small wire frame racks can house around 6 GPU mining rigs and cost only $50! An open air frame will set you back around $199 to $250 if you purchase one online.
*Note: Extra items are needed if you go with a small wire frame rack such as zip ties, plywood, and motherboard riser screws.
Motherboard -You won’t get far, if anyone, without a good motherboard. The motherboards I prefer over all other motherboards are the motherboards designed for gaming. There are motherboards that are designed for mining but they are also 3 times more expensive. Look for motherboards that have a total of 7 PCIe and PCI slots. The motherboard I recommend (again, I know there are others out there) is the ASUS Prime Z270-AR LGA 1151 ATX Intel Motherboard. I’ve seen people build out 10+ GPU mining rigs with these motherboards.
CPU - We have two brands of CPUs to choose from AMD and Intel. The AMD Ryzen 7 CPU is currently the best CPU to use for mining however its expensive. This is why I prefer to go with an Intel i3-7100. For mining, we don’t need a crazy good CPU. The CPU won’t be doing the mining, the GPUs will be doing the mining.
Hard drive - There are a few different kinds of hard drives we can choose from now. We have the classic HDD, the SSD, and now the M2. For mining, since I don’t require a super fast read/write, I go with the classic HDD. Typically a 1 TB hard drive is sufficient for mining. I believe that bitcoin’s blockchain size is around 130 GB currently. So a 1 TB hard drive is more than sufficient.
RAM - You are going to want to purchase 16GB of RAM. Typically this is 2 8GB sticks.
PCIe Risers - PCIe risers are used so that you don’t have to plug in your GPUs directly into the motherboard. Placing two GPUs next to each other, without PCIe risers, is impossible. Most motherboards have the PCI slots so close together that the GPUs we will be using nearly take up 2 spaces. PCIe Risers can be purchased on amazon and are generally inexpensive.
Power Supply (PSU) - THIS IS VERY IMPORTANT! You should calculate for yourself what your power consumption is going to be for your rig. The power consumption of each brand of GPU is different based on its core clock and memory clock. Use this website, http://www.coolermaster.com/power-supply-calculator/. DO NOT think that if your calculation comes up with 1250 watts that a 1300 watt PSU will be sufficient. PSUs, generally, are not designed to run at 100% their rating. Depending on when you are in your budget, it may benefit you to go with a platinum or titanium rated PSU. Shop for PSUs that are full modular. Once you get into the 1500 watt PSU size, these all generally have enough PCIe, and Sata power slots. Keep in mind, you will need 1 PCIe power slot for each GPU and you can use 1 Sata power slot per 2 GPUs. DO NOT EXCEED 2 GPUS PER SATA POWER SUPPLY!
Operating System - If you are here reading this, you are probably not familiar with Linux. Go with Windows 10 64-bit Home. I know a lot of people believe that Windows 10 is not great for mining but for simplicity reasons I recommend starting with Windows 10. Be sure to get 64-bit or else it will not read all 16 GB of RAM.
Power Switch - You can purchase these on Amazon. Do a search for “Computer Power Switch” and you will get tons of results.
GPUs - Time for the money makers! There are dozens of brands and manufacturers in which we can save this discussion for another thread. For now you are going to want to do your homework on which GPUs you want to mine with. You are going to want to come Return on Investments (ROIs). You are going to want to look earnings after the ROI period. All of which I’m going to start another thread on and it’s going to be very interesting!
DVD-ROM - You’ll need a dvd-rom so that you can install Windows. Don’t get a bootleg version online to save $100.
I hope this gives you all an in depth view of what all you need to build your own mining rig. The recommendation I made are to build these rigs on a budget. You want to spend as little money as possible because the more you spend, the longer your ROI period is.
Can’t wait to hear what you guys have to say about this!
