POWER SUPPLY (PSU)

 

 Post 6: Power Supply (PSU)


The power supply unit transforms the electricity from the wall into stable energy for the PC. It’s often underestimated, but it’s as important as the CPU or GPU.

Main features:

  • Wattage (W): determines how much power it can deliver. Example: a gaming PC usually needs between 600 W and 750 W.

  • Energy efficiency: PSUs with 80 Plus certification are more efficient and waste less energy.

  • Connectors: each GPU or motherboard requires specific cables.

Real-life example:

A PC with a powerful graphics card (e.g., RTX 3070) and a cheap 400 W PSU may shut down when gaming because it lacks enough power.

Tip:

Always choose a reliable brand PSU with enough wattage for your components.

STORAGE DEVICES

 

Post 5: Storage Devices (HDD, SSD, M.2)

Storage is where all data is permanently saved: the operating system, programs, documents, photos, and games.

Main types:

  • HDD (Hard Disk Drive): cheaper and large capacity (1 TB+), but slower.

  • SSD (Solid State Drive): more expensive, but much faster (boots in seconds).

  • M.2 NVMe: the most advanced SSD type, 5–10x faster than an HDD.

Real-life example:

A PC with an HDD might take 1 minute to boot, while with an SSD it starts in just 10 seconds. Also, loading a game like Fortnite may take 3 minutes on HDD and only 30 seconds on SSD.

Tip:

The best combo is to use an SSD for Windows and programs and an HDD for storing photos, movies, or documents.

GRAPHIES CARD (GPU)

 

Post 4: Graphics Card (GPU)

The GPU (Graphics Processing Unit) is specialized in processing graphics, images, and videos. It is essential for gaming, video editing, 3D animation, and even artificial intelligence.

 Main features:

  • VRAM (Video RAM): exclusive memory on the graphics card. More VRAM allows handling heavier graphics (e.g., 8 GB VRAM on an RTX 3060).

  • Clock speed: determines how fast the GPU processes data.

  • Ray Tracing: technology that simulates realistic light in video games.

  • CUDA Cores / Stream Processors: parallel processing units that boost graphical performance.


Real-life example:

If you try to play GTA V on a computer with integrated graphics, it may only run at 20 FPS. With a dedicated GPU like the NVIDIA RTX 3060, the same game can reach 100 FPS in high quality.

Tip:

  • For office work: integrated graphics are enough.

  • For gaming: at least a GTX 1650 or RTX 3050.

  • For video editing: GPUs with 8 GB of VRAM or more.

CPU INF

 

Post 3: The Processor (CPU)

The CPU (Central Processing Unit) is the main component of any computer. It’s often called the “brain” of the PC because it interprets and executes all program instructions. Without it, no computer could function.

 Main features:

  • Clock speed (GHz): shows how many operations it can perform per second. For example, a 3.5 GHz CPU can complete 3.5 billion cycles in one second.

  • Cores: each core acts like a mini-processor inside the CPU. Modern CPUs usually have between 4 and 16 cores.

  • Threads: allow each core to handle multiple tasks simultaneously.

  • Cache: ultra-fast memory built into the CPU for frequently used instructions.


 Real-life example:

When you open Google Chrome and Spotify at the same time, the CPU splits the instructions across its cores so you can browse and listen to music without freezing the system.

 Tip:

If you want a gaming or design PC, look for processors with at least 6 cores and 12 threads

Memory RAM INF

 

Post 2: RAM Memory

RAM (Random Access Memory) is the temporary storage where the computer keeps the data of currently running programs. The more RAM you have, the smoother your computer will run when multitasking.



"Here is a photo of a RAM memory and a video in case you want to know more↘↘↘"

More information here Ram Memory

Main features:

  • Volatile: data is erased when the PC is turned off.

  • Capacity: measured in GB (e.g., 8 GB, 16 GB, 32 GB).

  • Speed: measured in MHz (e.g., DDR4 at 3200 MHz).

  • Dual channel: using two identical sticks allows RAM to work faster.

 Real-life example:

If your PC has only 4 GB of RAM, opening a modern game while running 10 browser tabs will make it freeze. With 16 GB, everything runs much more smoothly.

 Tip:

  • For basic use: 8 GB.

  • For gaming and editing: 16 GB or more.

  • For professionals (architecture, AI, 4K editing): 32 GB or more.

MOTHERBOARD INF

Post: 1 Motherboard

The motherboard is the main component of a computer. It is an electronic circuit board that connects and allows communication between all the other components of the system, such as the processor (CPU), RAM memory, graphics card, storage devices (hard drives or SSDs), and other peripheral devices.

It acts as a control center where all the circuits and connections are integrated, enabling different components to work together in a coordinated way. Additionally, the motherboard includes slots, ports, and sockets that allow for the installation and connection of additional hardware.


Types of Motrheboards


1. According to form factor (size and physical shape):

  • ATX (Advanced Technology eXtended): The most common type, standard size, offers many expansion slots.

  • Micro-ATX: Smaller than ATX, with fewer slots, ideal for more compact PCs.

  • Mini-ITX: Even smaller, used in compact systems or HTPCs (Home Theater PCs).

  • E-ATX (Extended ATX): Larger than ATX, with more space for components and connections.

2. According to usage or segment:

  • Desktop motherboards: Designed for regular desktop PCs.

  • Server motherboards: Optimized for stability, more storage ports, support for multiple processors.

  • Workstation motherboards: For professional tasks, with higher capacity and performance.

  • Laptop motherboards: Integrated and more compact, designed specifically for each laptop model.

3. According to processor socket:

  • Intel: For example, LGA 1151, LGA 1200, LGA 1700.

  • AMD: For example, AM4, AM5, TR4 (for Threadripper processors).
