Frequently Asked Questions: Desktop PC

Should I buy a finished desktop PC or buy and assemble the hardware components individually?

Whether you buy a complete system or buy the hardware components individually and then assemble them depends on your skills. If you are not very familiar with PC hardware, we would recommend buying a finished PC.

This is a little more expensive than building it yourself, but you get a ready-made computer and you can start right away. Another advantage is that the hardware components are usually very well coordinated with one another.

If the PC does not work or a hardware component is broken, you also have a contact person for repairs and warranty issues. Most of the time, the operating system and the most important drivers are already preinstalled, so all you have to do is switch on your PC.

Do you know a little about connecting hardware and want to save some money on top of that? Then you should buy the hardware components individually and assemble them yourself.

Instructions usually come with the hardware components that describe how to wire the component to the rest of the PC. If you still have problems assembling it, you can watch video instructions on YouTube. Here you will be shown exactly how to wire the components together.

With home-made PCs, of course, you also have to buy and install the operating system separately. But that shouldn’t be a problem. Then the drivers, for example for the graphics card, have to be installed. Usually a CD is included here. You can also easily download and install most drivers from the manufacturer’s website.

What do I have to consider in terms of hardware if I decide to build my own PC?

When building your own, you are responsible for ensuring that your hardware is perfectly coordinated. There are a few tips you should follow for this. First of all, choose your desired processor. In the product description you can see which socket the processor needs.

Next, when you choose your motherboard, make sure that it also supports the socket on your processor. If you buy a processor cooler, you also have to look at the socket.

There are also processors with a free multiplier (at Intel these are marked with a “K”). That means you can overclock these processors. For this, however, you also need a mainboard that allows overclocking.

When it comes to working memory (RAM), there are memory modules of different sizes (2, 4, 8GB) and differences in terms of type (DDR3, DDR4), clock frequency (2133, 2666 …) and latency (CL7, CL9, CL11, CL16 …) . Basically you should always make sure that you install at least two RAM modules (or even several) in order to benefit from dual channel.

You also have to make sure that your motherboard supports the respective type. Your motherboard also determines the maximum possible clock frequency. The higher the clock frequency and the lower the latency the better.

The individual hardware components require a certain amount of power (watts). Especially with gaming PCs, where the graphics card and the processor need a lot of power, you have to make sure that your power supply unit has enough power. For the individual components, you can usually find the required performance in the product descriptions.

You then have to add up these individual performances and add a buffer (+ ~ 25%). There are also so-called “power supply computers” on the Internet. Here you only have to enter your components and suitable power supplies will be suggested.

When it comes to the case, you have to consider how big your computer should be and which motherboard you want to use. In modern PCs, mainboards with the size or form factor ATX are mostly used.

But there are also Micro-ATX, Mini-ITX, Nano-ITX and Pico-ITX. The most important thing is that you like your case visually and that it supports the desired form factor of the motherboard.

If you are unsure which hardware components are right for you, you can get additional opinions on forums. Often you will even be given a sample configuration there.

What are the advantages of buying the desktop PC with a monitor?

Many PC set offers offer a monitor, keyboard and mouse as a free supplement. Here you have to decide for yourself whether this is a purchase argument for you.

Because these monitors, keyboards and mice are not always the best. These are mostly inexpensive entry-level products that do their job. If you plan to play PC games or edit pictures on this monitor, these monitors will not be sufficient. However, if you just want to watch videos or browse the web, this monitor is sufficient.

It is usually worth buying your own monitor. Then you can determine both the size and the quality yourself.

Which operating systems are recommended?

Windows 10 Home is recommended for all users. Windows 10 Pro or Windows 10 Enterprise are not recommended for normal users because they are a lot more expensive.

Windows 10 Pro and Windows 10 Enterprise can be recommended for people who primarily save important work on their PC and who need additional security.

Windows 7 can also be recommended. Here, however, you should prefer Windows 10, as this operating system is more modern and more secure.

Linux or other operating systems cannot be recommended for normal users because they have limited functionality.

Windows 10 Home
Usable for everyone

Windows 10 Pro / Enterprise
Brings additional security, but significantly more expensive

Windows 7
Basically suitable for everyone, but no longer the latest

Linux or others
Not quite as intuitive to use, only for more experienced users

If your desktop PC is delivered without an operating system, you have to install it first. Here you should note, if you have an SSD and an HDD, that you install the operating system on the SSD when selecting the storage space.

This will start your PC and Windows Explorer faster, so that you can save a lot of time. In addition, you should make sure that you know the location of your downloads. Move Chrome, Firefox and Internet Explorer to your HDD so that they do not put additional strain on the SSD.

These are the most important points to keep in mind. Setting up an operating system gets easier from time to time and is therefore also suitable for beginners.

How loud is a desktop computer?

Another important point in every office, but also at home, is of course the volume of the device. The noise is mainly caused by the fans, which are responsible for cooling the hardware.

When gaming, but also with complex CAD applications, the hardware is often very stressed. This leads to an increased temperature development in the housing. The temperature then has to be removed by fans.

If you prefer a rather quiet computer, you should pay particular attention to the case fan, the fan in the power supply unit and the CPU and GPU cooler. An insulated housing also reduces noise development.

In general, it can be said that most factory fans are not very quiet. If you attach particular importance to a quiet working environment, we recommend that you buy the fans separately.

There is also the option of using water cooling. If you want to install water cooling in your system, you have to consider a few things.

In the simplest case, the water cooling consists of a cooling block, a radiator, a pump, an expansion tank and hoses that connect everything. The cooling block absorbs the heat from the component and transfers it to the water. The pump transports the heated water to the radiator, which then releases the heat into the air.

The mere fact that you need considerably more components than with air cooling makes water cooling a bit more expensive.

Component compatibility is also a problem. If you want to replace hardware components of the PC, the cooling block, for example, may also have to be replaced.

The biggest advantage is that the radiator can basically give off the heat anywhere. It could also be placed outside the housing as long as the pump can pump the water to it.

This makes you more flexible in designing the cooling system. Furthermore, water cooling systems are somewhat quieter than air cooling systems.

Does it make sense to buy a used desktop PC?

In principle, used hardware cannot be recommended. We always advise you to use a new system. This has the following reasons:

  • A used system is like buying a used car. There are people who clean their cars, do regular checks and drive with caution. On the other hand, there are also people who never clean their car and do not treat it well. The same goes for a PC.
  • A PC may have been used and maintained little. But it could also be overclocked and neglected, so that it will be defective very quickly.

So if you decide to buy a used PC, you should always keep this in mind and examine everything carefully before you make your purchase decision.

Types of Desktop Computers

First of all, you have to think about the area of application your future computer should have. Basically one can differentiate between four different areas of responsibility:

  • Computers for office work
  • Gaming PCs
  • Computer for image and video editing
  • Desktop PCs for CAD applications

Each of these areas of responsibility has different requirements for your computer. Depending on what you use your desktop PC for, your hardware will be more or less stressed.

By and large, the hardware also determines the price of your PC and is therefore one of the most important decision criteria.

In the following section we would like to help you to find the perfect PC for your individual application. For this purpose, the individual task areas are discussed in more detail and we give you tips for your optimal hardware configuration.

Desktop Computer for the Office: Advantages & Disadvantages

If you just have to do simple office work, you can safely do without powerful hardware. This also makes the PC a lot cheaper.

A standard processor and a standard graphics card are sufficient for everyday applications such as Word, Excel and Powerpoint or for surfing the Internet. Nevertheless, there are certain “must-haves” that make working with a PC a lot more pleasant.

A fast SSD (Solid State Drive) is almost a must these days. This saves you long waiting times when starting the system and opening your programs and files.


  • No powerful hardware required
  • Usually faster start of the PC
  • Comparatively cheap


  • Not as powerful as other models
  • Gaming and video editing are only possible to a limited extent

You should also pay attention to your RAM capacity (main memory). Less than 4GB (gigabytes) of RAM are no longer up to date. With 8GB RAM you are well prepared for the future.

The processor does not have to be a “high-end model”. For example, an Intel Core i3 processor would be recommended. Processors for office work are available for around US$100. Since the processor usually already has an integrated graphics unit, it is not necessary to buy a graphics card. The integrated graphics card is completely sufficient for everyday work with office programs and the like.

Gaming Desktop Computer: Advantages & Disadvantages

The world of computer games is becoming more and more realistic and detailed. It is even possible through virtual reality not only to play the game but to immerse yourself in it and experience it. This of course requires a certain amount of power from your PC.

The rapidly growing e-sports scene also contributes to a certain extent that gaming PCs are in great demand. Computer games require ever more powerful hardware in order to keep up with the competition.

One of the most important components in a gaming PC is definitely the graphics card (GPU). She is responsible for the calculation and display of the image. If it is too weak, the picture jerks.

Of course, it also depends on the resolution and the graphics setting in which you want to play. Basically, you should make sure that your graphics card has at least 4GB VRAM (memory). However, in order to be prepared for the future, we recommend a graphics card with 6-8GB VRAM.


  • Powerful hardware
  • Fast processor
  • Good graphics, often VR also possible
  • Versatile in use


  • Often quite expensive
  • Takes a lot of energy
  • Usually an extra power supply is required

The heart of every computer is the processor (CPU). This should not be too slow either, otherwise it will become a “bottleneck” for the graphics card. A new generation of processors comes onto the market almost every year. But don’t worry, even with a processor that is several years old, you can often play without problems.

If you buy a new processor, you can use a solid quad-core processor from Intel (Intel Core i5). The newly released processor generation from AMD (Ryzen 5 and 7) also offer good performance and usually even have a better price / performance ratio in contrast to Intel.

If you want to set up your PC for a particular game, you should take a look at the game’s system requirements. These are a good guideline when choosing hardware. You can usually check the requirements on the game manufacturer’s website.

The size of the RAM also plays an important role. It should be at least 8GB (better 16GB). An SSD also has advantages in the area of ​​gaming. This significantly reduces loading times in games if they are installed on an SSD.

A gaming graphics card and a fast processor naturally require more power than normal hardware. This is why the power supply unit is of great importance for gaming computers. Here you should pay attention to the power (watts) and the efficiency of the power supply unit.

The degree of efficiency indicates how many watts the power supply unit has to draw from the network in order to be able to supply the computer with a certain amount of energy. We recommend a power supply with an 80 Plus Silver or Gold certification. This not only protects the environment, but also saves electricity costs.

Desktop Computer for Image/Video Editing: Advantages & Disadvantages

For graphic designers in particular, the question arises again and again: What does the optimal PC for image processing programs (such as Adobe Photoshop) or video editing programs (such as Adobe Premiere) look like?

In this application area, the key component is the processor. Rendering videos, in particular, takes an enormous amount of time if you have a cheap or outdated processor. Therefore it should be at least an i5 or better an i7 processor with hyperthreading from Intel.

To put it simply, hyperthreading means that the processor has, for example, 4 logical cores, but the system is “led to believe” 8 cores. This allows the processor 8, instead of normally only 4, to execute commands in parallel.

The capacity of the RAM is also very important. Your computer should have at least 16GB of RAM built in. Since RAM doesn’t cost the world anymore, we would even recommend you buy 32GB.


  • Fast processor
  • High memory capacity
  • Good graphics
  • Versatile in use


  • Often expensive
  • sometimes an extra SSD is necessary

You can save a little on the graphics card. Most processors are already sold with sufficient onboard GPUs. This means that the processor already has an integrated graphics unit. If you still want to render and edit images a little faster, you should use a dedicated graphics card.

Here, however, a middle class card in the price segment of US$50-150 is completely sufficient. Of course there are also GPUs beyond the US$400 mark. However, these no longer bring the decisive added value.

An SSD also makes sense in this area of application. This speeds up the start of the application and the PC. In addition, you should buy a 1-3TB HDD as videos and pictures require a lot of storage space. An SSD with this capacity is currently still very expensive and therefore not recommended.

Desktop Computer for CAD Applications: Advantages & Disadvantages

Whether for business or pleasure, a fluid and precise representation of the constructed components and assemblies is very important when working with CAD programs such as AutoCAD or CATIA. To be able to guarantee this, we recommend that you buy a professional graphics card that has been specially optimized for this area of ​​application. Specifically, this is about the Nvidia Quadro and AMD FirePro models.

These graphics cards cost a little more compared to conventional GPUs, but have noticeably more power. Complex and large 3D assemblies bring standard graphics cards to their knees. Memory is also very important. We recommend using at least 16GB RAM here.


  • Fast processor
  • Professional graphics card
  • High performance
  • Large RAM


  • Often expensive
  • sometimes an extra SSD is necessary

The number of cores in a processor is not that important in CAD applications, as most design programs do not support more than one core.

It is therefore much more important that the performance per core is very high. The processor should have a high clock frequency (a lot of GHz) in order to guarantee the best possible performance.

The CAD application should be installed on an SSD hard drive. This means that loading times can be extremely shortened.

Desktop Computer: Purchase Criteria

In the following we would like to show you the factors you can use to compare and rate desktop PCs. This will make it easier for you to decide which PC is right for you.

In summary, these are:

  • Dimensions & Weight
  • Motherboard
  • Processor
  • Graphic Card
  • RAM
  • Hard Disk
  • Optical Drive

The following paragraphs will explain the individual criteria in more detail and you will learn how to classify them.

Dimensions & Weight

You should think twice about whether you prefer a large tower or a simple PC in console format. This decision has some advantages but also disadvantages.

The advantage of large tower PCs is that you can easily replace components. There is a lot of space inside, which makes wiring the components a lot easier. The heat generation is also not as concentrated as with small computers.

Therefore, the heat dissipation also works better. For large cases, you can also install a motherboard with a larger form factor.

This gives you more connections and allows you to install more hardware components. The disadvantages of large towers are certainly the weight and the larger space required. This also makes them more difficult to transport.

Small PCs with Micro-ATX or Mini-ITX motherboards are very easy to transport and have a certain “style factor”.

Unfortunately the heat development is worse than with larger PCs. Therefore you either need faster rotating fans, which means a higher noise development, or you cannot use the hardware components to their full capacity.

Even with the connections, it doesn’t look so lush on smaller motherboards. The most important ones are there, but not to the same extent as with a mainboard with ATX form factor.

If the PC is mainly used in one and the same place, you should rather use a larger PC (mainboard form factor ATX). If you want a desktop PC for on the go, a mini PC is just right for you.


The motherboard, which is also known as the mainboard, is the control center in every computer. The individual hardware components are connected to one another here. Specifically, this concerns the processor, graphics card, memory, power supply, hard drive, drive and fan.

All of these components are wired to the motherboard. How many internal and external connections your PC has is basically determined by the mainboard – interfaces such as USB, PCIe, SATA, LAN, audio, VGA and HDMI.

As already described above, every motherboard has a specific socket. This defines which processors can be installed on the motherboard. If you want to overclock your processor, your motherboard has to support that too. The type and type of main memory are also regulated by the motherboard.

The type and number of PCIe slots is very important for expansion cards such as graphics cards or special hard drives. If you want to install several graphics cards (SLI or Crossfire) in your system, you have to make sure that your motherboard also supports this.

The SATA connections are crucial for connecting the hard disks and drives. However, there are already motherboards that offer new M.2 SSD slots. These are particularly fast.

There are also only a limited number of ports for case fans. If you want to attach additional fans, you have to read the product description of your mainboard carefully.

Your motherboard also determines the BIOS. For example, if you are using an Asus motherboard, it will also have the Asus BIOS preinstalled. Most manufacturers’ BIOS only differ in certain additional features (integrated fan control, etc.).


The processor is the heart of a PC. It is also known as the CPU (Central Processing Unit). The processor performs arithmetic operations and controls parts of the computer. Data is entered, processed and then output again at the end.

The processor only understands data in binary code (zero and one). Therefore all information has to be encoded in binary code.

The number of cores on the one hand and the clock frequency on the other hand are important for the CPU. The more cores a processor has, the more instructions can be processed simultaneously. 1, 2, 4, 6 and 8 core processors are common. However, there are also high-end models with 12 or 16 cores.

The clock frequency indicates how fast the commands can be executed. It is usually given in GHz (gigahertz). 1 GHz corresponds to one billion oscillations / processes per second.

The higher your processor clocks, the more important cooling becomes. The electronics can be damaged by excessive heat. That is why fans or water cooling are mainly used.

A processor also includes a control unit. This control unit stores and reads data from the working memory. Therefore the type and the maximum clock frequency of the RAM are influenced by the processor. Most processors already have an integrated graphics unit. This is mostly sufficient for normal “office” operation.

Graphic Card

The screen remains black without a graphics card. The graphics unit converts the data from the processor so that they can be displayed on a screen. The graphics unit is also known as a GPU (Graphic Processing Unit).

How important the performance of the GPU is depends on the specific application. In office computers, the integrated graphics chip in the processor is often sufficient. When gaming, you can’t avoid a dedicated GPU.

With CAD applications you should use a special GPU that has been optimized for this area of ​​application. A mid-range GPU is often sufficient for image or video editing.

Basically, however, there are a few factors with which you can compare GPUs. Each graphics card consists of a graphics processor and video memory (VRAM). As with the CPU, the clock frequency is very important. The higher the clock frequency, the faster the graphics card. The size of the VRAM is especially important in games.

The higher the graphics settings and the resolution, the more memory is required. For normal applications 1-2GB is usually sufficient, for workstations you need between 2-4GB. If you want to play current games with high graphics settings, 6GB and more are often required.


The performance of a computer depends not only on the CPU and GPU but also on the memory. It is the link between the CPU and the hard disk. The main memory is also known as RAM (Random Access Memory).

The connection between CPU and main memory is much faster than that between CPU and hard disk. Therefore, the RAM stores the data that has just been processed by the processor or it loads data from the hard disk that will be processed shortly. This makes the system much faster.

An important decision criterion is first and foremost the type of main memory. The current version is DDR4 RAM. But there is also an older version (DDR3). The storage capacity is also of great importance. 4GB is often sufficient for normal office computers.

When it comes to video editing, however, 32GB is a great advantage. Basically you should make sure that you have installed at least 2 RAM modules. If you want 4GB that would be 2 x 2GB. This means that you benefit from dual channeling and your data transfer rate is extremely increased.

The clock frequency in megahertz (MHz) is the next deciding factor. There are, for example, 1600, 2133, 2400, 2666, 3000 and 3200. The faster the clock frequency, the better. However, the type and frequency must be compatible with the processor and motherboard.

Another decision criterion is latency. If you have to choose either a higher clock speed or lower latency, you should prefer lower latency. Latencies are represented like this, for example: CL 7-7-7-21 or simply CL7. The lower this is, the better.

The clock frequency and the latency do not have the decisive influence on the speed of the PC, except perhaps for complex games and video editing.

Hard Disk

The operating system and all of your computer’s files are stored on the hard drive. A basic distinction can be made between three different types of hard drives:

  • HDD
  • SSD
  • Hybrid

The cheapest of the three hard drives is the HDD. These are available in capacities of several terabytes (TB). However, the HDD does not have particularly high data transfer rates either.

Therefore it mainly serves as a “data grave” for films, photos, music and larger folders and programs. SSDs have the advantage that they have extremely high data transfer rates. They are therefore a lot more expensive than an HDD.

But you should at least get an SSD with 100-250GB. This allows you to install the operating system and the most important programs on the SSD. Your computer and the installed programs start a lot faster.

The hybrid hard drive is a middle ground. This combines an HDD with a small but fast flash memory. The most important programs and data are stored on the flash memory and benefit from the increased data transfer rate.

There are also different sizes. A distinction must be made between 2.5 ″ and 3.5 ″ hard drives. SSDs are also available in the form of expansion cards. These then use either an M.2 or a PCIe slot.

Optical Drive

If you still work with CDs and DVDs, an optical drive is necessary. In times of the Internet, CDs are becoming less and less important. Programs, drivers, films and even games are increasingly offered as downloads or streams. This is why desktop PCs are rarely equipped with an optical drive.

If your PC doesn’t have one either, but you still need one, you can buy an external drive as an alternative. An external drive is already available for US$20-30.

Facts about Desktop Computers

How can I retrofit WiFi in the desktop PC?

If your new PC does not support WiFi and you do not want to run a LAN cable through your room, there are two different options that allow you to transmit wirelessly.

  • PCIe WiFi card
  • WiFi stick

PCIe cards can be installed on the PCIe port on your mainboard in the PC. This means that peripheral devices such as WiFi cards or sound cards can be connected to the PC. These can already be purchased cheaply. However, you have to dig deeper into your pocket for the latest WiFi standard.

However, you should only choose this variant if you trust yourself to access the hardware of your PC. Since a PCIe card is installed using a connector system, even those who are not too experienced can install a PCIe card in their PC.

A WiFi USB stick is the easiest way to connect your PC to WiFi. However, these USB sticks cannot achieve a long range, so this can be recommended for smaller apartments. For larger apartments or a house, a PCIe WiFi card or a powerline adapter can be recommended.

This USB stick is easy to install. After it has been plugged in, all you have to do is install the driver and you can connect to your WiFi.

What is the best way to clean a desktop PC?

If your PC is hotter than usual and its performance is getting worse, it is time to clean your PC.

Dust settles on and between your fans, so that their performance is restricted and can no longer cool the PC properly.

This heats up this, so that the clock rates are reduced. A vacuum cleaner can remove most of the dust with a little distance.

However, if you want to do a thorough cleaning, you will need a toothbrush or paintbrush. This will allow you to remove even the toughest dust.

Of course, you could also apply new thermal paste to the CPU, but this will require a bit of experience, which is why we cannot recommend this for everyone.

Which desktop PC consumes little power?

Basically, it can be said that low-performing PCs consume less power. But you certainly don’t want to work with the slowest PC. Therefore, you should pay attention to which certification the power supply has.

The following certifications exist:

  • No certification
  • 80 plus
  • 80 plus bronze
  • 80 plus silver
  • 80 plus gold
  • 80 plus platinum
  • 80 plus titanium

The higher the certification, the better the efficiency of the power supply. A power supply without certification can have any efficiency. This means that the power supply can only conduct as much current as it wants. Most of the time it conducts very little current, so this power supply cannot be recommended.

A PSU with a certification has an efficiency of at least 80%. That means that 80 of the current also reach your computer. Now the difference between certifications is that better certifications have better efficiency.

An 80 Plus Titan power supply has a ~ 15% better efficiency than an 80 Plus power supply. However, these power supplies often cost a lot of money and can only be recommended for a few.

In general, you should look for at least 80 plus silver power supplies. These are sufficient and have the best price-performance ratio.

Which is better desktop computer or notebook?

There is no general answer to the question. The advantage of notebooks is that you are much more mobile with them. There’s also no need to lug around an external keyboard or screen.

The biggest disadvantage compared to desktops is the price. A notebook with the same performance costs many times more than a desktop PC. Furthermore, the temperature development is much greater than with a floor-standing PC. The components are concentrated in a much smaller space.

In order to be able to dissipate the heat, you need faster rotating fans. This is why notebooks are usually a bit louder than desktop computers.

The lack of upgradeability of notebooks is also a disadvantage. The components are often firmly soldered and cannot be easily removed. This is often very annoying, especially with gaming notebooks. If the graphics card can no longer display current games smoothly, you have to buy a new device.

How do I make my old PC faster?

Observe the following tips and you will notice that your PC will be noticeably faster:

  • Always keep your PC up to date (current updates and drivers)
  • Uninstall programs and delete data that you don’t need
  • Defragment and optimize your hard drive (just enter “defrag” in the Windows search and start the program)
  • Deactivate unimportant programs from the autostart. This will make your PC start up much faster. Basically you only need your antivirus software and the most important drivers at system start. (You can find the autostart in Windows 10 in the Task Manager)
  • Only place shortcuts for programs and folders on the desktop. Large amounts of data on the desktop make your PC start much slower
  • Uninstall unimportant toolbars from your browser. These throttle your surfing speed and are also quite annoying.

What do I have to consider if I want to upgrade my PC?

If your hardware components are out of date, there are two options. Either you buy a new PC or you replace individual components. The cheaper option is definitely upgrading.

Here you should only note that the new hardware components must be compatible with your previous system. The motherboard and the power supply play a crucial role here. Your motherboard must be compatible with the new component.

Otherwise you have to swap this too. The power supply is mainly about performance. If your new component needs significantly more power than the old one, you have to make sure that your power supply unit can provide this additional power.
