HOW TO DESIGN A CUSTOM-BUILT GAMING PC
A custom-built Gaming PC Rig is the best way to get exactly what you want. You have total control over all the components, and you will be able to play the games you want, at the frame rates you want, without sacrificing performance.
Building your PC is not as difficult; not only is it enjoyable, but it also provides an upgradeable platform for technological changes as your gaming environment evolves.
Buying a custom-built gaming PC isn't difficult, but it can get a bit overwhelming at times. That's why we've put together this comprehensive, step-by-step guide to help you purchase your Gaming PC.
WORK OUT YOUR BUDGET & GAMING NEEDS
Before buying a gaming computer, we recommend working out a budget that you are comfortable with and the games you would like to play.
An entry-level, cheap gaming computer might be a good start, but it wouldn’t be suited for more cutting-edge modern games.
For playable frame rates, you may need to spend and look at a mid-range option from $ 1,250 to $ 2,000. These will be well-equipped for most modern games, with some capabilities in VR gaming and content creation.
Machines over $2000 will provide you with extra performance, video rendering & streaming capabilities, along with an enhanced VR experience. Liquid Cooling solutions are highly recommended for these ultimate extreme gaming rigs.
COMPONENTS OF A GAMING PC
When investing in a custom-built PC, you have 2 options. You can thoroughly research each component on your own and create a custom build from scratch, or you can find a pre-made build online and adjust it to suit your specific budget and needs. When choosing parts for your PC, there’s a lot more to consider than just price and popularity. Here are the components you’ll need to build a Gaming PC:
Pro tip: If you're building this PC to play a specific game, check the game's recommended system requirements and plan accordingly.
PROCESSOR (CPU)
The best analogy for a CPU is that of an engine in a car. It accounts for the performance of your computer. The CPU & Video Card (GPU) are critical in determining the performance and frame rate per second (FPS).
The processors are categorised based on their clock speed, cores, and threads to determine their performance. The core count indicates the number of processors the CPU has, which in turn determines the number of tasks the CPU can perform simultaneously. Core count and clock speed serve as direct measures of performance for processors within the same generation.
The clock speed (GHz) tells us how quickly the CPU performs each task. Some higher-end CPUs feature hyper-threading, which enables each core to run multiple threads, offering improved performance on threaded software.
Intel processors are renowned for their superior single-core performance, making them particularly well-suited for gaming. They are criticised frequently for being expensive & more restrictive on overclocking. AMD processors, on the other hand, are known for their stronger multi-core performance and overclocking abilities and are more popular with gaming enthusiasts. They offer much better value for your money.
Pro-tip: Most modern CPUs are multi-core, and many modern games are designed to take advantage of this, so you should look for a CPU with at least four cores. Additional cores can be helpful as you start layering on more tasks, such as recording and streaming your gameplay.
MOTHERBOARD
Depending on your processor, a compatible motherboard is required to build a Gaming PC.
Overclocking Abilities - “Do or Don’t”
The main difference between a low-end motherboard and a high-end one is primarily the overclocking capabilities. Intel manufactures the “K-Series” (usually a suffix), indicating the overclocking capabilities, while all modern AMD processors will be fine. For Intel Processors, a Z-series motherboard is required, while for AMD, a B or X-series motherboard is needed.
Motherboard Size & Expansion Slots
Once you’ve decided whether you want overclocking or not, it’s time to decide on your MOBO and corresponding case size: ATX, MATX, or ITX.
ATX is the biggest, and ITX is the smallest—the fewer RAM and PCIe slots you have. MATX is the most popular configuration and is typically less expensive than the other two. You would normally look for ATX if you want more expansion slots for adding more interface cards, while ITX is mostly used for small form factor or portable gaming computers. ATX motherboards may require a slightly larger case, which also adds to the cost.
Pro-Tip: The motherboards have the least, if any, effect on gaming performance. You don’t need to buy a gaming motherboard for a great gaming rig.
GRAPHIC CARD (GPU)
The GPU (Graphics Processing Unit), also known as the Video Card, will be the component that has a major impact on your gaming performance. The GPU renders the actual graphics that you see at the resolution & settings the graphics card has been set at.
There are two types of graphics processors: Integrated and discrete. Integrated graphics processors are integrated with the CPU. Integrated graphics have improved significantly throughout the years, though they are still generally less powerful than discrete graphics.
The CPU & GPU need to work in tandem; if the CPU isn’t processing fast enough, the GPU’s visual output will be bottlenecked, and you will experience lag since it will have to wait for the CPU to catch up.
When selecting a graphics card, Clock speed may not be indicative of overall performance; VRAM (Video RAM) is a much more relevant metric. The higher the VRAM, the better the performance and the higher the screen textures. A 6GB Video Card will outperform a 2GB graphics card.
Don’t despair if all you can afford is a 2GB Video Card, as even those will offer decent performance at 1080p with standard-definition textures.
Decent gaming would want to look for graphics cards that produce consistent frame rates of at least 60 frames per second (FPS) at your desired resolution (anything lower may look choppy), while gamers looking to play in virtual reality should look for cards that produce consistent frame rates of at least 90 fps.
Pro tip: The GPU isn't the only component that affects frame rate, so it's essential to balance out your build to avoid performance bottlenecks elsewhere.
MEMORY (RAM)
RAM, or Random Access Memory, is the next most important component for gaming performance. Using single-channel RAM will affect the CPU’s performance. Using Dual or Quad-Channel whenever possible is highly recommended. This is where the PC stores data that it is actively using (those "instruction lists" that the CPU needs to read and execute).
RAM speed usually won’t make a huge difference in gaming or common multitasking unless you are running productivity applications. RAM quantity certainly makes a difference; the more RAM you have, the better your gaming system will perform.
- 4GB - Suitable for light gaming, not recommended for modern games.
- 8GB – Balanced Performance. Great for Gaming Experience.
- 16GB – Recommended Option. High performance, running all modern games with optimal performance.
- 32GB – Not very advantageous for a Gaming PC Platform, but more needed for Workstations running productivity applications.
Figuring out how much RAM you need can be tricky because having more RAM than you use will do nothing (except waste money), and having too little RAM will negatively affect performance. Ideally, you want the perfect amount of RAM for you/your build. (But generally speaking, the average gaming rig needs 8 - 16GB of RAM.)
Pro-tip: RAM that's faster than what your system supports will reduce clock speed to run at your system's capabilities. High-speed RAM will run at a standard (lower-than-advertised) speed unless it's overclocked.
STORAGE – HARD DRIVES OR SOLID-STATE
There are two main types of storage: Solid-state drives (SSDs) and hard disk drives (HDDs). There are pros and cons to both, and the good news is that you don't have to choose just one.
Unlike the standard hard drives, SSD (Solid State Drive) is a storage drive with no moving parts. This makes it much, much faster than an HDD (hard disk drive).
SSDs are much more expensive per GB of storage. Having a combination of SSD for the boot operating system and programs, including games, along with an HDD for secondary storage to hold data and backup files is a good combination. This makes it much more responsive by speeding up the boot times and loading your favourite games.
Modern SSDs come in two protocols: SATA (the older protocol, which has higher latency and lower peak bandwidth) and Non-Volatile Memory Express (NVMe), which utilises the PCI Express interface to achieve higher performance.
Pro tip: You don't have to pick just one. Many people use a small SSD as a boot drive (for the operating system, games, and other programs) and fill the rest of their bays with cheap HDDs for maximum storage capacity.
POWER SUPPLY UNITS (PSU)
The Power Supply Unit (PSU) is also a critical part of the. Gaming PC Design, please don't worry about this. It needs to be robust and powerful enough to handle all current and future components.
Ensure you have sufficient wattage for your system. The total power dissipation PSU requirements listed on GPUs will give you some idea of what to expect, but you may opt for these if you plan on overclocking.
Cable management is very. Important: not only does it look like a clean build, but it also doesn’t obstruct the airflow, which can cause the system to underperform. PSUs are available in non-modular, semi-modular, and fully modular styles. Non-modular is a cheaper option as PSUs have all cables permanently attached. Semi-modular PSUs come with a handful of essential cables pre-attached and are generally less expensive than full-modular styles. Full-modular PSUs are even easier to work with than semi-modular PSUs, but you'll be paying for the added convenience.
The PSUs are available as Standard or 80+ Certification. This can then be further categorised as Bronze, Silver, Gold and Platinum. This indicates the robustness and the efficiency of a power supply.
Pro-tip: 80+ ratings refer to efficiency. The higher the efficiency, the less excess power the PSU will consume and the less heat it will produce. A PSU with an 80+ certification is highly recommended.
CASE (CHASSIS) & COOLING FANS
Fortunately, this one is the simplest. First, pick a size that matches your motherboard size: ATX, MATX, or ITX.
You’ll also want to ensure that your case of choice has sufficient room for your GPU (ATX and MATX cases will generally accommodate even the largest modern GPUs). ITX cases, however, will be much less likely to accommodate large cards, so keep this in mind.
Now that you’ve decided on a size, ensure that you find a case with support for modern features, such as USB 3 headers.
High-end gaming PCs generate a lot of heat. You will get some default cooling features with your components: GPUs and PSUs have dedicated fans, and cases often come with a couple of fans.
You’ll also want to ensure that your case has an adequate cooling setup —if it has room for two intake fans and vents for those fans, your basic airflow needs are most likely being met.
For water-cooling setups, you’ll want to find cases with room for mounting a radiator on top-- this is fairly common in ITX builds, where there isn’t much room for larger air coolers.
There are two main ways to cool your PC: Air and liquid.
Air cooling utilises fans to circulate hot air through your system and away from components, thereby preventing overheating. Air cooling depends on efficient airflow inside the case to move hot air away from components, so that any airflow restriction can be problematic.
Liquid cooling uses a liquid coolant (such as distilled water) to soak up heat from components and move it to a less restricted area (where the radiator is placed). Liquid cooling is less dependent on airflow inside the chassis and, therefore, more efficient at cooling specific components.
Once you’ve gotten compatibility and cooling out of the way, the rest comes down to build quality and personal preference.
If you’re dedicated to keeping your system cool (especially important for overclockers), you should be prepared to invest in extra case fans. You just need to ensure that you use good fans with ball bearings to make them quiet. You always have the option of using RGB fans to create a nice ambience.
Pro-tip: In an air-cooled system, more fans do not necessarily mean better cooling. Fan quality and placement make a difference.
GAMING PERIPHERALS
Gaming Monitors, Keyboards, Mice, chairs, and headphones, as well as other peripherals, mostly come down to personal preference. You don't need to purchase these items with your components, but you will need a display, a keyboard, and a mouse to set up your system after you build it.
Pro-tip: Keep build balance in mind when picking peripherals — if you have the best components in the world but are still using a 1080p, 60Hz monitor, you won't be taking full advantage of your hardware.
