Cheap PC build guide

[Nacho Libre]

Hi all. Since I'm building another gaming PC (this one is for a friend's kid) i decided to document and share the experience, in the hope it's useful. I realize there is a ton of PC building tutorials out there, and you should watch as many as possible if you are looking into PC gaming. Even if you decide to buy a prebuilt PC, it's good to be knowledgeable about the whole process, from picking the components to fit your budget and meet your performance targets (a game into itself!) to putting it together and making it work.

In this first part, I will cover the motherboard (a.k.a. MOBO), the CPU (Central Processing Unit) and fan, together with the RAM memory, the tools you need, some general precautions and tips, including the rationale for picking the parts vs. the allocated budget and the performance goals.

Now, the budget was set by my friend at about US$680, plus a reasonable assembly fee that I will not disclose.

So, my first choice was the CPU/MOBO combo, and I opted for a Ryzen 5 5500 to go with a B550 Gigabyte motherboard. Since this supports DDR4 RAM memory, I went for 16 GB (2x8 GB modules) of T-Force Delta R sticks. I have worked with Gigabyte motherboards and T-Force memory, so I'm comfortable with them. This is my first Ryzen build after using Intel in my personal PC.

These are the parts in question (pardon the background, as I'm working in the dinner table and the tablecloth is themed for Autumn):



Tomorrow, I'll illustrate the assembly of these components. Cheers!

Part 1: Motherboard/CPU assembly.

It's important to always check that the boxes containing your components arrive in good shape, with no signs of having been opened, and that all parts/manuals/warranties are accounted for.



As you can see, the MOBO comes wrapped in an anti-static bag, and comes with an I/O shield that fits in the case, a SATA cable (for a storage unit that uses that connection), and a quick installation guide that you should always read.



Out of the bag, I placed the motherboard over its carboard box. This gives you a stable, pliable, and static-free surface to work, as you push the RAM sticks into place, and screw the fan over the CPU.

I marked the main parts we are going to use in this step. If you look closely, you will see that the motherboard is full of useful labels to guide you. And the little black square on the bottom left corner is the actual B550 chipset that controls the MOBO: Don't touch, and don't bother.



As we look closer, above and below the CPU socket (or seat) there is a couple of brackets that you will need to remove in order to fit the CPU's cooling fan. Use a regular Phillips screwdriver (star-shaped head) to unscrew by applying just the necessary force. Put the brackets and screws back in the fan's box.



After you remove the brackets, you'll notice four stands where the fan will be screwed over the CPU. Notice the little arrow in the corner. This is an important guide to correctly place the CPU.



Now gently, pull the lever out and up as shown. Unlike Intel's chips there isn't much pressure, so it doesn't "snap".



Now you can unbox the CPU, which for this model also contains a stock fan that we will use. Carefully remove the CPU from its wrapper and hold it like I do in the next picture. Warning: It is deceptively heavy.



Here you see the arrow that needs to be aligned with the one in the socket.



On the backside there are the connecting pins that go into the socket. DO NOT TOUCH THEM AND DO NOT BEND THEM.



Now, breath, relax and gently place the CPU on its seat by making sure the arrows are aligned. DO NOT PRESS THE CHIP INTO PLACE. Then pull down the lever under that little side tab and see it is not loose. This locks the chip into place.

Coming up: Fan and RAM installation.

Part 2: Let's install the fan!




Carefully unbox the fan included with the CPU and turn it upside down. The central metal area is evenly covered with thermal paste. While many builders prefer to remove it and use a brand thermal paste (or thermal pads), I don't recommend it if you are doing a first build. It works just fine, just don't touch it.



Check where the fan will connect. In this case, to a four-pin connection located down of the bottom right screw hole for the fan, and between the M.2 slot (left), the first slot for the RAM stick (right), and a screw hole for the motherboard that looks like an asterisk.



Now carefully place the fan over the screw holes with the AMD tab pointing to the CPU.



As you can see, you will need your Philips screwdriver. Just hold the top of the fan with one hand and screw in a cross-pattern with the other. Don't force the screws if you feel they are not going down, just wiggle the fan a bit to align the screws to the holes, by applying even force in all sides.

As a side note, this is easier than the stock Intel's fan where you have to drive 4 pins through the motherboard and then turn and lock them into place.



Anyways, now that you screwed the fan, check by holding the top of the fan and raising the motherboard just a couple of inches (or cm). You will need to do this later when you put the motherboard into the case.



Now hold the connector and see those tabs.



To plug the fan connector, see that the bottom metal tab aligns with the plastic tabs and push. If it feels too tight, with your fingernail pull the metallic tab slightly towards you, and the connector will slide into place.



Now for some basic cable management, coil the cable like this, and your fan installation is done.
