What You Need to Know About Desktop PC Components

Before creating your own desktop PC, there are some important factors to consider. The initial step is selecting the necessary components, which may be unfamiliar to you. These include a CPU, graphics card, and storage device. These components are the building blocks of your desktop PC.

Storage device

When shopping for a desktop PC, it is important to choose the right storage device. There are two basic types: hard disks and SSDs. SSDs offer higher speed and higher storage capacity. Hard disks are a bit slower than SSDs, but they still serve an important purpose in different scenarios.

Storage devices can be large or small, and their capacities vary from computer to computer. Most computers use a hard disk or SSD. They can be networked together, so a computer can access larger storage systems. Hard drives have come a long way from their early days, ranging from 5 MB to several terabytes. Choosing the right storage device is essential for optimal system performance.

Storage devices store data and applications within the computer system. This type of storage keeps data persistent even without power. Hard disks are the most common type of internal storage, but solid-state drives are slowly gaining popularity. If you need more space than a single hard disk can accommodate, consider purchasing a disk array controller.

Apart from hard disks, desktop computers also include removable storage devices. You can store files on USB flash drives or cloud storage services. Moreover, desktop computers typically come with a disc drive that can read and write CDs and DVDs.


A computer’s processor is a core component that is responsible for carrying out user instructions and completing calculations. It is also referred to as the central processing unit (CPU). The processor is typically found directly on the motherboard of most PCs, though some are also found on a specialized slot on a computer’s daughtercard.

The number of cores on a processor chip is an important consideration. A CPU can be as little as one core, or as powerful as eight. The higher the number of cores, the better, especially for professional designers and video editors. For everyday use, a dual-core processor is probably sufficient. If you plan to use your desktop PC for professional software, quad-core is the sweet spot.

Graphics card

You may be wondering how to remove the graphics card in your desktop PC. First, you will need to turn off the power supply, unplug the monitor, and unhook any cables connected to the GPU. Secondly, you will need to find the GPU retention clip. This is a protruding part on the right-hand side of the PCIe x16 slot. These clips vary in design, but they all work in the same way.

The graphics card processes the information sent by the CPU and translates them into a graphical representation. Modern graphics cards can process an incredible number of instructions simultaneously. They can draw images tens or hundreds of times per second, ensuring smooth performance. But a graphics card is not the only component in your desktop PC.

GPUs are composed of billions of transistors, and some are so powerful that they can use hundreds of watts. They can also cost upwards of a thousand dollars. As such, they are among the most studied PC components. TechSpot is one of the places that devotes the most time to GPUs.

While you can find GPUs from several manufacturers, the most common types of graphics cards are made by AMD and Nvidia. Other manufacturers also produce graphics cards using these chips, but they usually add some extra tweaks to differentiate them. For instance, one manufacturer’s version may be more powerful or come with better fans. A different manufacturer’s version may also have better warranties.

Sound card

If you want to enjoy the best audio quality, you should invest in a desktop PC with a high-quality sound card. These cards can boost your PC’s audio performance and provide 5.1 or 7.1 surround sound. If you’re a musician, you’ll want to invest in a desktop PC that supports MIDI and offers an additional MIDI port. A good sound card will also give you an option to pair with a 7.1 speaker system.

If you’re a music producer, it is also a good idea to invest in a high-end sound card and an audio interface. Several models feature multiple inputs, including a microphone jack for recording audio. However, if you’re a casual music listener, a cheaper sound card may be sufficient.

You’ll need to download a driver for your audio card. Most operating systems require a specific driver for each piece of hardware. These drivers will manage data connections between your hardware and the operating system. Although some operating systems already come with drivers for audio cards, others will require you to download them.

Before the introduction of the sound card, PCs could only produce beep sounds. These beeps could vary in frequency and duration, but could not be adjusted or played back. The beeps served as warnings and signals. Some game developers used beeps with different pitches to create music for their games, but these early sounds were not realistic.


The main components of a desktop PC include the CPU and the motherboard. While these are the most important components, there are other components that make up the computer. For example, the processor is important, but it can’t work without memory and a power supply. All of these components are important for the computer to function properly.

A motherboard is a large Printed Circuit Board (PCB) that connects all of the various components of a PC. It also serves as the central nervous system, controlling how much data and electricity will be circulated throughout the circuit board. It is typically made of multiple layers of substrate and thousands of small copper wires.

Motherboards are produced in different sizes and shapes. Most consumer motherboards are available in the ATX or Micro-ATX form factor, but the size of the board can also depend on what other components are installed on it. The ATX form factor is the most common, and is used in most desktop computers. It’s the industry standard and is widely preferred by enthusiasts. The smaller Mini-ITX form factor is used in compact PC builds.

Motherboards come with numerous connectors and ports. Almost every peripheral on the market will connect to a PC via USB. But some modern motherboards come with USB-C ports that support Thunderbolt 4, a high-speed form of data transfer. Thunderbolt 4 adaptors allow data to flow at 40Gb/s and support up to two 4K displays.

Hard drive

There are many components that make up a hard drive. These components connect to the motherboard using a standard SATA connector. A desktop computer’s hard drive will be the 3.5-inch variety. The diameter of the spinning disk inside is 3.5-inches, while laptop computers use 2.5-inch drives.

The four main components of a hard disk drive are a spindle, disk platter, actuator arm, and read/write head. These components follow industry standards for form factor and physical size. The form factor will determine whether or not the hard drive is compatible with various computing devices. If you are unsure of how to install and upgrade your hard drive, seek the help of a computer tech.

When buying a new hard disk drive, be sure to check the storage capacity of the drive. The most common drive capacity is around 2TB. A 4TB drive can store nearly three years of work. The capacity of a 5TB drive is equivalent to four DVDs. Some hard disk drives can be as large as 10 TB.

Hard disks can have both mechanical and logical failure. The mechanical component may break down due to wear and tear, while the logical component may malfunction due to a glitch in the software. In case of a logical failure, the software that runs on the hard drive becomes corrupted, causing the computer to crash or freeze during bootup.
