The most important components of a gaming PC explained

Anyone who delves into the topic of gaming PCs quickly encounters a number of technical terms: CPU, GPU, motherboard, RAM – but what exactly do they mean? In this article, we'll explain all the important components of a gaming PC – in an easy-to-understand and practical way.

1. CPU – the brain of the PC

The Central Processing Unit (CPU) , also called processor, is responsible for all computing operations.
In gaming, for example, it takes care of physics, AI, and all background processes.

For beginners: AMD Ryzen 5 or Intel Core i5
For demanding gamers: Ryzen 7 / i7 or higher
💡 Tip: A powerful CPU is especially important for strategy games or simulations with many units.

2. GPU – the graphics card as the performance center

The graphics processing unit (GPU) is the most important component for gaming. It calculates all visual content and determines FPS, detail, and resolution.

Full HD: RTX 4060 / RX 7600
WQHD: RTX 4070 / RX 7800 XT
4K: RTX 4080 / RX 7900 XTX or higher

Without a good graphics card, you can't enjoy smooth gaming – it directly impacts your gaming experience.

3. RAM – the main memory

Random Access Memory (RAM) is your system's short-term storage. The more RAM, the more tasks your PC can handle simultaneously.

Minimum: 16 GB for current games
Optimal: 32 GB for multitasking, streaming and high graphics settings
Also pay attention to the speed (e.g. 6000 MHz for DDR5) and dual-channel configuration for more performance.

4. Mainboard – the control center

The mainboard (motherboard) connects all components together.
Here you can decide, for example, about:

RAM type & amount
CPU compatibility (socket)
Number and type of ports (USB, M.2, PCIe, etc.)
It must match the CPU – a Z790 board, for example, is designed for 13th/14th generation Intel Core processors.

5. Storage – SSDs & HDDs

For fast loading times, you need an SSD (solid state drive). It's up to 10x faster than a traditional HDD.

For games & system: NVMe SSD with 1–2 TB
For large amounts of data (e.g. recordings): additional HDD with 2–4 TB

💡 Tip: Without an SSD, modern games start noticeably slower – now standard on all new PCs.

6. Power supply – invisible but crucial

The power supply supplies all components with power. Not only the wattage is important, but also the efficiency (e.g., 80+ Gold).

550–650 W for entry-level setups
750–1000 W for high-end GPUs and many components
A good power supply protects against voltage spikes and ensures stability.

7. Cooling – air or water?

A gaming PC generates a lot of heat – good cooling is a must.

Air coolers : affordable, low-maintenance, reliable
Water cooling (AIO) : better temperatures, especially for high-end CPUs

In addition, there are case fans that should ensure a clean air flow.

8. Housing – more than just a shell

The case influences design, volume and expandability:

Enough space for GPU & fan?
Good air circulation?
Dust filter & cable management?
Choose a case that not only looks good but is also functional.

Conclusion: Coordinate all components

A powerful gaming PC is only as good as its interaction.
CPU, GPU, RAM, motherboard, storage, and power supply must all be compatible. With a little know-how (or the right advice), you can put together your perfect setup.
