How to Assemble a Gaming PC
The question of purpose is the most important when assembling a gaming computer because PC games have entirely unique system requirements. While games with demanding 3D graphics primarily require the graphics card, building simulations and real-time strategy games benefit mainly from the performance of the processor.
By exploring your preferences, you can configure a gaming PC with optimal performance for your favourite games cost-effectively and make the most of your budget.
The Components of a Gaming PC
- Graphics card (GPU): renders the image on your gaming monitor.
- Processor (CPU): calculates the gameplay.
- Motherboard: connects all components together.
- Memory (RAM): enhances the responsiveness of your gaming PC.
- Hard drive (SSD or HDD): stores your games and affects loading times.
- CPU cooler: keeps the processor at low temperatures.
- Power supply unit (PSU): provides all components with the right voltage.
- Case: houses the delicate PC hardware.
How much does a gaming PC cost?
How much gaming PC can I get for my money? The question of budget is crucial for performance, as well as the appearance of your rig. You can purchase a gaming computer for as little as around 600 euros, but you can also spend thousands of euros. The cost question is closely tied to which games, at what resolution, and with what graphics details you want to play. If you want to play triple-A titles, the latest games with the best graphics, in 4K and UHD resolution, and at maximum details, then invest accordingly in your gaming hardware. Game developers nowadays make sure their PC games run on as many devices as possible, but the latest PC games truly shine in their full glory on a high-end gaming PC.
Gaming PC for online game
Many popular online games can be played smoothly on budget gaming PCs. Additionally, it's important to clarify beforehand whether you want to stream on Twitch or YouTube with the new PC, as a streaming PC has additional requirements compared to a pure gaming PC.
From "Entry-Level" to "Enthusiast Gaming PC" - What's the perfect gamer PC?
Gaming hardware is often divided into four categories and classified according to price and performance. This helps manufacturers position the hardware in the market and helps consumers find the appropriate hardware for their PC. These four categories are:
- "Entry-Level" or the beginner segment
- "Mid-Level" or the mid-range segment
- "High-End," also the top tier of gaming PCs
- "Enthusiast," referring to computers where money is not a concern
Entry-Level: Affordable gaming PCs
PCs in the entry-level segment, or budget PCs, are aimed at gamers who either spend relatively little time gaming on the computer or primarily play games with low hardware requirements in Full HD (1920 x 1080) at medium to high settings.
Many browser games, MMOs, and free-to-play titles can be played on an affordable gaming PC from the entry-level segment. Additionally, numerous popular eSports titles can be played with a budget gaming PC from this class.
Mid-Range: Gamer PCs in the mid-price segment
In the mid-range, we find gamer PCs that can smoothly handle games at WQHD resolution (2560 x 1440 pixels). Even at high detail settings, these gaming PCs do not falter. Excursions into virtual reality (VR) are also possible with these gaming PCs, and some games can be displayed in 4K or UHD resolution (3840 x 2160 pixels).
High-End Gaming PCs: Expensive computers fulfill gamer dreams
Powerful High-End PCs are equipped with a good graphics card, a powerful processor, and fast RAM (memory). They utilize fast NVMe SSDs as storage drives. A high-end gaming PC effortlessly handles virtual reality and games can be played smoothly in 4K UHD resolution with maximum details. In lower resolutions like WQHD (1440p), contemporary high-end gaming PCs achieve extremely high FPS without compromising on graphics.
For enthusiasts, we go one step further and offer individually configurable high-end gaming PCs with custom water cooling, overclocked by professionals like der8auer or 8Pack, to squeeze out the maximum performance from the silicon.
The optimal PC hardware for the perfect gamer system
For a pure gaming PC, the graphics card and processor are the most important hardware components, as they are primarily responsible for gaming performance. Additionally, the speed of memory and storage drive plays a role in how smoothly your games run, but once these PC components meet the recommended requirements, adding more RAM or an even faster SSD is unlikely to significantly increase frames per second in games.
Graphics Cards for Gaming PCs
As the most crucial component when assembling a gaming PC, the graphics card (GPU) typically consumes the lion's share of your budget. Generally, there are two developers of graphics chips for gaming graphics cards: AMD and NVIDIA.
These companies also manufacture graphics cards themselves, but the majority is produced by partners (AIBs) of the developers. As a third player, Intel enters the field with its first generation of dedicated 3D graphics accelerators, Arc. Here's a brief overview of the two graphics chip developers.
The differences and advantages of AMD Radeon and NVIDIA GeForce graphics cards
AMD Radeon
- AMD FreeSync synchronizes the monitor's refresh rate to the GPU's FPS
- AMD FSR for increased FPS through upscaling
- AMD Adrenalin Software
NVIDIA GeForce
- NVIDIA G-SYNC synchronizes the monitor's refresh rate to the GPU's FPS
- NVIDIA DLSS for increased FPS through upscaling
- NVIDIA GeForce Experience Software
The best graphics cards for your gaming PC in 2024
Both developers offer a wide range of graphics cards for gaming PCs. The current graphics card series in the gaming segment are the 'RTX 40' series from NVIDIA and AMD's Radeon RX 7000 series. In principle, you should opt for the latest generation, but older graphics cards are still worth considering.
Once you've chosen a graphics card series (e.g., Radeon RX 7000 / RX 6000, GeForce RTX 40 / RTX 30), you still need to select the right variant (e.g., Radeon RX 7800 XT, GeForce RTX 4080). In general, the higher the number, the faster the graphics card.
The current gaming graphics cards from AMD and NVIDIA at a glance
We've sorted the current AMD Radeon and NVIDIA GeForce gaming graphics cards that we install in our gaming PCs by performance for you. The most expensive and high-performance models are listed at the top:
NVIDIA GeForce RTX 40 Series
Once you've chosen a graphics card series and variant, you're faced with the agony of choice, as numerous licence partners of AMD and Intel offer different variants with the same graphics processor. Each of these partners relies on its own developed cooling solutions to cool the graphics chip, voltage regulators, and graphics memory. In addition to the cooler design, board partners such as ASUS, MSI, Gigabyte, or Sapphire also offer graphics cards with different clock speeds.
PC assembly: Avoiding bottlenecks
The graphics card should be matched to the processor, as if the graphics card is significantly faster than the processor, it can lead to a 'CPU bottleneck'. In such a bottleneck, the processor, which is too slow for the graphics card, slows down the GPU, preventing your gaming graphics card from reaching its full potential. By the way, it's the same in reverse: A GPU bottleneck occurs when the graphics card is significantly slower than the processor and holds it back.
CPU & Motherboard
The processor is the central processing unit of your computer. It is where all data is processed, calculated, and distributed. The mainboard (motherboard) is the foundation for the hardware, where all other components are united. The mainboard and processor must be compatible. Otherwise they often cannot be assembled. The compatibility between these PC components is defined by the socket on the mainboard, which must match the chosen processor.
An example of processor and mainboard compatibility
An AM5 motherboard is only compatible with AM5 CPUs from AMD, and a Socket 1700 CPU from Intel is only compatible with a Socket 1700 motherboard. Also important for compatibility is the chipset. If you want to utilize all features of an Intel processor with the "K" suffix, you will need a Z or X chipset from Intel. While this may sound complicated, it's actually basic because product descriptions always specify which CPUs a motherboard is suitable for.
Configure a gaming PC quickly and easily
With our PC configurators, you're on the safe side because we've checked the compatibility of all parts. This means you don't have to worry about the interplay of PC hardware when you assemble your new gaming computer with us
How to choose the right CPU for your needs
Like with graphics cards, processors can also be divided into four classes. A high-end CPU is the perfect partner for a high-end graphics card and can also form a strong duo with enthusiast-grade graphics cards. Here, too, higher numbers generally indicate more performance.
How to estimate CPU performance based on naming
AMD CPUs
How many cores should my desktop processor have?
Before making a purchase, consider how many processor cores you need for your gaming PC. This depends on the PC games you want to play. If you primarily want to play first-person shooters, especially the maximum clock frequency matters, as fast-paced 3D games typically utilize a lower number of CPU cores effectively.
It's different for simulation games like Anno, Civilization, The Settlers, or Surviving Mars: Here, the processor is particularly demanding, and high frame rates play a subordinate role. Many of these games scale excellently with more CPU cores and benefit from a high-end CPU.
Using a gaming PC for video editing, image processing, and streaming
If you also want to use your gaming PC for live streaming, video editing, and CAD, investing in a high-end processor and graphics card, as well as more memory and larger, faster SSDs and hard drives, is worthwhile.
The CPU Cooler
The CPU cooler is responsible for regulating the temperatures of your processor in the gaming PC. Pay particular attention to ensuring that the cooler is compatible with the CPU or motherboard socket. At the same time, the fan should be large enough and powerful enough to dissipate the heat generated by the processor. If a CPU has a Thermal Design Power (TDP) of 65 watts, the CPU cooler should be able to dissipate at least this TDP.
High Cooling Performance Makes a Silent Gaming PC
If you want your gaming PC to run as quietly as possible, opt for a larger CPU cooler, where the cooling surface is large enough that the additional fans don't have to run at full load to dissipate the heat.
What are the advantages of liquid cooling?
In a liquid cooling system, heat is transferred through a circuit filled with coolant from the CPU cooler to one or more radiators. The coolant is then cooled by fans on the fins of these heat exchangers.
Water Cooling: Custom Loop vs. All-in-One Cooler
When it comes to water cooling, there are two options to choose from: the ready-to-use all-in-one (AiO) water cooling and the custom water cooling. An all-in-one water cooler typically consists of a closed loop of pump and radiator. The pump is mounted like a CPU cooler, and the radiator is attached to the fan slots of the case. In contrast, a custom water cooling system is assembled from individual components.
Our pre-built gaming PCs with all-in-one water cooling are perfectly tailored to the configuration of the gaming computer and ensure optimal cooling. If you configure a custom PC with water cooling, our PC experts from King Mod Systems will build you a perfect cooling circuit according to your wishes with 36 months warranty.
RAM: How much memory does a gaming PC need?
RAM, also known as main memory or Random-Access Memory (RAM), is an essential component in every computer system. In RAM, data is temporarily stored that the CPU needs for processing operations, and frequently used files are kept for faster access. Because RAM is a particularly fast and widely connected type of memory, it prevents the main processor (CPU) of the gaming PC from being unnecessarily slowed down.
"Memory for budget gaming PCs
Currently, even budget gaming PCs are equipped with 16 GB of memory. DDR4 RAM with 3,200 MHz in the form of a dual-kit, meaning two memory sticks, is considered average. Modern motherboards support this fast memory
DDR5 RAM: The latest and fastest memory for gaming PCs
Even faster, though also pricier, is DDR5 memory. The successor to DDR4 is supported by Intel's 12th Generation Core processors, Alder Lake, and AMD Ryzen 7000 CPUs. Memory speeds and latencies are evolving positively with DDR5. DDR5 RAM is becoming faster and more affordable. We offer customizable gaming PCs with both memory technologies. Faster DDR5 RAM includes specifications such as 6,000 MHz with CL30 latencies or 7,200 MHz with CL34 latencies.
How much RAM does a mid-range gaming PC need?
DDR5-6000 RAM represents a significant leap forward in memory technology, offering blazing fast speeds and enhanced performance ideal for mid-range gaming PCs in 2024. With its impressive data transfer rates, DDR5-6000 RAM ensures smoother gameplay experiences, reducing loading times and providing snappier responsiveness in gaming environments.
Its increased bandwidth and improved efficiency enable seamless multitasking and smoother gameplay, making it a perfect choice for gamers seeking a balance between performance and affordability. Whether you're engaging in intense gaming sessions or tackling demanding tasks, DDR5-6000 RAM delivers the necessary power to elevate your mid-range gaming PC to new heights, ensuring you stay ahead of the competition without breaking the bank.
RAM for High-End Gaming PCs
For those pursuing peak performance in High-End-Gaming-PCs,32 to 64GB of DDR5-7200 RAM offers unparalleled speed and efficiency. With blistering data transfer rates and low latency, exemplified by CL34 timings, this cutting-edge memory technology ensures lightning-fast responsiveness and seamless gameplay experiences. Elevating gaming to new heights, DDR5-7200 RAM enables smooth multitasking and effortless handling of the most demanding gaming environments, making every moment in the virtual realm an unforgettable adventure in speed, fluidity, and precision.
In the enthusiast segment, it's common to see 64 or even 128 GB of RAM utilized in dual- or quad-channel mode. Here, the focus is on the fastest possible memory, and in addition to clock speeds, the connection to the CPU plays a significant role. On many High-End Desktop (HEDT) platforms, memory can be connected to the CPU in quad- or even octa-channel mode, providing greater transfer speeds.
Festplatten: SSDs and HDDs
Data storage in the form of hard disk drives (HDDs) and Solid-State Drives (SSDs) serve to store files, applications, and games on fast flash components. They store items such as the operating system, programs, and of course, your game library.
Both HDDs and SSDs offer space for huge amounts of data. Typically, hard disk drives are cheaper than SSDs for the same amount of storage, but they are also significantly slower and generate audible operational noise. HDDs are primarily worthwhile for storing large amounts of data that are not accessed regularly.
Unlike HDDs, SSDs do not contain moving parts, making them nearly silent. Traditional SSDs are the same size as notebook HDDs, measuring 2.5 inches, and also utilize the SATA III protocol. They can be installed in compact cases, such as behind the motherboard tray. M.2 SSDs take up no additional space at all, as they are built directly onto the motherboard.
NVMe SSDs also offer the highest data transfer rates, utilizing the PCI Express interface. With PCIe 3.0, these flash storages already achieve outstanding speeds of around 3,500 MB/s or more. SSDs with PCI Express 4.0 double this value, and PCIe 5.0 SSDs increase it once again.
Which SSD to buy for a gaming PC?
For a gaming PC, an SSD primarily means speed. Even budget gaming PCs in 2024 come with a 1TB NVMe SSD. In standard configurations, traditional hard drives are being phased out. These are better suited for external hard drive enclosures or NAS systems. Even a small SSD with capacity for the operating system and a few games offers significant advantages, such as short loading times in games.
If you need more storage space, our PC configurators always allow you to equip your gaming computer with additional storage. However, this won't increase FPS. Nevertheless, current games with high-resolution texture packs can quickly consume all the storage space on your gaming PC.
Is an NVMe SSD with PCIe 4.0 worth it for a gaming PC?
This question is often hotly debated and sparks controversy. SSD drives connected via PCIe 4.0 offer significantly higher access speeds compared to SATA SSDs. Sony and Microsoft are pushing for the adoption of fast NVMe SSDs with their gaming consoles, the PlayStation 5 and Xbox Series X, citing their ability to deliver short loading times. However, console players have little choice in the matter, as they are restricted in their hardware options. For gaming PCs in 2022, NVMe SSDs with PCIe 3.0 are still an excellent choice. At our store, you have the freedom to configure your gaming PC according to your preferences.
PSU: The Power Supply Unit
The power supply unit (PSU) in a gaming PC is responsible for supplying power to the electronic components. The rated power of your PC power supply is measured in watts, while efficiency is indicated, for example, by the 80-PLUS certification. Additionally, a power supply can be fully or partially modular, meaning you can detach none, some, or all of the internal power cables. This helps reduce cable clutter in your gaming PC.
The PC power supply, apart from its rated power, doesn't directly influence the performance of your gaming PC, so one might think it's an area where you could "cut corners." However, a high-quality branded power supply is typically more efficient and equipped with better protection circuits. But what power supply is needed for the new gaming PC?
To determine the power requirements of the power supply for a gaming PC, it's helpful to look at the graphics card. This is usually the largest power consumer in a gaming computer. Information on the recommended power of the power supply can be found in the description. These typically include a reserve for the consumption of the CPU and other components, such as HDDs and lighting. For example, an NVIDIA GeForce RTX 4060 typically recommends a power supply with a rated power of at least 550 watts. From this smallest Ada Lovelace graphics card, the demands on the power supply increase steeply: High-end graphics cards like the GeForce RTX 4090 and the Radeon RX 7900 XTX require PC power supplies with a rated power of 850 watts or more.
List of typical PSU Form Factors for Gaming PCs:
- ATX power supplies for most gaming PCs
- SFX power supplies for compact gaming PCs
- SFX-L power supplies with more power than SFX
Lower electricity costs thanks to higher efficiency
80 PLUS is an initiative to promote power supplies with an efficiency of 80 percent or higher. For certification and classification into one of the five performance levels, a power supply must achieve a specific minimum efficiency at various load points depending on the class. The higher the efficiency, the more efficient the PC power supply is, and the less electricity it draws from the outlet to deliver its performance.
Is an expensive power supply worth it for a gaming PC?
In principle, one should never skimp on the power supply, but also, a power supply with too much capacity should not be chosen, as it may otherwise operate in the less efficient low-load range. High-end power supplies deliver more precise voltage values on the 12, 5, and 3.3-volt channels. They are quieter and have a longer lifespan, which manufacturers support with longer warranty periods. Our gaming PCs are exclusively equipped with certified power supplies that match perfectly the offered PC hardware, so you can't go wrong when configuring.
Quiet power supplies for a silent gaming PC
The components in a power supply need to be cooled. This can be done actively by a fan, which always spins at a constant speed. Semi-passive fans adjust the fan speed to the temperature and load of the power supply. Fanless power supplies are cooled passively. Here, it is essential to ensure that the PSU is correctly mounted in the case and that air from outside can be used for cooling. Many power supply manufacturers employ a semi-passive cooling technique, where the fan only starts when needed, such as when the gaming PC is under load.
The Best Gaming PC Cases
PC cases come in many different sizes and shapes, ranging from huge full towers to the smallest mini-ITX cases. But which case is the right one for a gaming PC? The choice of the right case depends on many factors, and the following bullet points can help in choosing the right PC case:
- What is the form factor of the motherboard?
- How will the gaming PC be cooled?
- Where will the case be placed?
- What colour should the case be?
- Should the case have elements made of tempered glass?
- Do you want RGB lighting in your case?
Full Tower Cases: The Largest PC Enclosures
As full towers are particularly large cases that offer ample space for hardware and cooling. Water-cooled enthusiast gaming PCs are often housed in such cases. Also referred to as full towers, these cases are perfect for a water-cooled gaming PC as they typically offer many options for hardware and fan or radiator installation. However, they also take up a large footprint and are usually quite heavy.
Mid-Towers: The most popular PC cases
Mid-tower cases are among the most widespread PC enclosures. They offer ample room for hardware and are available in all price ranges. There is also a wide variety of options available aesthetically, with mid-tower cases featuring tempered glass and RGB LED lighting being just as common as more understated towers. When choosing a mid-tower, pay attention to the available radiator slots if you plan to install an AiO water cooling system or a custom loop. Our gaming PC configurators are perfectly tailored to the respective selection of complete and custom water cooling solutions.
Micro-ATX Cases: Compact Cases for Gaming PCs
Micro-ATX cases are slightly smaller than mid-towers and are designed to accommodate motherboards in the Micro-ATX form factor. They still offer space for a powerful gaming graphics card and efficient cooling for the gaming PC.
The main compromise here is primarily with expansion cards because PC cases of this size typically offer 4 expansion slots. However, this is entirely sufficient for most gaming rigs, as usually only one expansion card is installed: the graphics card.
Mini-ITX Cases: For the Gaming PC on the Desk
Mini-ITX cases today come in all colours, shapes, and sizes. Some are barely smaller than a Micro-ATX case, while others are hardly larger than a gaming console. Thanks to the wide range of components available and sophisticated engineering, even high-end gaming PCs with custom loops are possible in the smallest computer cases. And this is happening even as graphics cards continue to grow.Gaming PCs with RGB LED lighting
For many, a gaming PC is more than just a tool or a simple machine. Rather, their computer becomes increasingly a prestige object and a show-piece. To properly showcase the gaming hardware in their PC case, RGB LEDs are becoming increasingly common.
We offer customizable custom-builds and pre-built gaming PCs with and without RGB lighting.

The Accessories to Complete Your Gaming PC Setup
A gaming computer setup is often complemented by corresponding PC gaming gear such as a gaming mouse and a mechanical keyboard. This type of gaming peripherals is usually equipped with particularly durable switches and keys. Gaming mice also feature sensors with high polling rates, which can be adjusted as needed.
Internal microprocessors often enable the storage of configured profiles, while the commonly available RGB LED lighting can be adjusted via software or on the device itself. This allows for coordination of the accessory lighting with the RGB lighting of the hardware.
