How to build your own gaming PC

 My home computer is getting older and older and is starting to act up, the hardware requirements are growing, and next year, we will see some great and graphically impressive games like Cyberpunk 2077 or Watch Dogs Legion. With this in mind, I decided to write a tutorial on which modern PC I would build. I would class it as a middle class PC. And with no further ado, I present to you the Nova!

1. A Powerful CPU

A CPU handles almost all computing tasks you throw at a computer, and as an effect of that it consumes the most energy. When choosing a CPU, it's important to look at several factors, such as core count, TDP, which means how much power it takes, clock rates, which dictate how fast the CPU runs, and HyperThreading, which essentially simulates extra cores for the CPU.

To maximize the PC's performance, processor and the graphics adapter shouldn't bottleneck each other. When you buy an RTX 2080 and a R5 CPU, the computer will not fare well.

CPU in general can be sorted in three distinct classes: low-end, mid-range and high-end. There is also an ongoing war of sorts between Intel and AMD due to AMD's introduction of Ryzen architecture, and, as such, this is an ideal time to buy a CPU.

I chose AMD Ryzen R7 3700X, since the Zen 2 architecture makes for an excellent gaming PC, which is also capable of running other software. Other pluses include 8 cores, a wide instruction set, and great overclock capabilities. Its price is about 325 USD.

As a cooler, I recommend Scythe SCNJ- 5000 Ninja 5. It boasts great cooling capabilities at a price of 60 dollars.

2. GPU

GPU or Graphical Processing Unit is responsible for drawing everything you see on your screen at any given moment. It eases the CPU of graphical drawing tasks, however for more basic operations, a integrated GPU in processor is also sufficient.

The requirements are similar to CPU; TDP, clock speed. However, there are several GPU-specific attributes, such as VRAM size, bus size and to lesser extent also the physical size of the card.

Two current manufacturers who hold a duopoly of sorts are AMD and Nvidia, however Intel wants to enter the market in 2020 with their Xe series.

I chose Gigabyte GeForce RTX 2070 Super OC, because it's very powerful, silent, has nice RGB lighting and interesting white design, and will hold its ground for years. It costs arou 590 $ on Amazon.

3. Case

Case is the most visible part of the computer and serves as a mounting space for fans, connectors, and in older cases, optical disk drives. (´There are also floppy disk drives, but that's a topic for the retro section)

​While choosing a case, you don't need to look at specs, because most cases support ATX motherboards and that's all that matters. You just need to look for the design which you like. I chose the Cooler Master Masterbox K500L, because I like the angled design of its front panel.

4. Hard Drive

Hard Drive is a data storage, which uses the magnetic storage technology to save your data. It's usually cheaper, but louder and slower than an SSD. In most computers (including mine) it serves as a primary data and program storage.

I chose the WD Blue 2 terabyte hard drive, since it's got a lot of space for my games and other stuff, and all that for 50 US dollars.

5. A Swift SSD

SSD (Solid State Drive) is a data storage device with no moving parts. Its more expensive and has a smaller capacity than most HDDs, however, it's a lot quicker and completely silent.

As a system drive, I chose Kingston A2000, because it's quick, large for an SSD, and uses NVMe with speeds up to 2200 MB/s. It costs 60 USD on Amazon.

6. RAM - Random Access Memory

A memory which stores running apps and processes. Relies on power from the PC, which means that once the PC is turned off, RAM is wiped. Today's standard is 16 to 32 gigabytes.

I chose HyperX Predator RGB 16 GB, which has clock speed of 3200 MHz. I'll later probably buy another set of RAM so I have 32 GB, but this will suffice. They cost 108 USD on Amazon.

7. PSU

PSU is essentially a transformer and a fan packed in small box. It transforms mains voltage (220 - 230 V in Europe, 120 V in the USA) to 3, 5 and 12 volts, the common voltages used in a PC. It then supplies it to the rest of the components via cables.

I picked Seasonic Focus Plus Gold, because it is cheap, has 80PLUS-GOLD certification, and is silent.

8. Motherboard

Connects various components and expansion cards. Usually has integrated Ethernet, sound card, disk controller, and many more which were previously attached to ISA/PCI cards.

The most important conditions in choosing the motherboard is the chipset, socket type and to lesser extent size.

I chose GIGABYTE B450 AORUS ELITE, since it provides a good foundation for my Ryzen 7 CPU, has interesting design and can control the RGB lighting of all components. It costs 110 USD on Amazon.

My PC gaming build: Summary
