Power supply

 POWER SUPPLY


What is a Power Supply?

The Power Supply Unit (PSU) is the component responsible for converting alternating current (AC) from the electrical outlet (110V or 220V) into direct current (DC) that the computer’s internal components need to operate.

Without it, no component (motherboard, CPU, GPU, drives, etc.) can function.


Main Functions

  1. Power conversion:

    • Converts AC (alternating current) → DC (direct current).

    • Typically provides +12V, +5V, +3.3V (and sometimes −12V and +5VSB).

  2. Voltage distribution:
    Delivers power through different voltage rails to the motherboard, CPU, GPU, storage devices, and peripherals.

  3. Electrical protection:
    Includes built-in protection systems such as:

    • OCP (Over Current Protection)

    • OVP (Over Voltage Protection)

    • UVP (Under Voltage Protection)

    • OTP (Over Temperature Protection)

    • SCP (Short Circuit Protection)


Internal Components

A PSU contains several electronic modules:

  1. EMI Filter: Removes electrical interference at the input and output.

  2. Rectifier and PFC (Power Factor Correction): Improve electrical efficiency and stabilize input current.

  3. Transformer: Converts high-voltage AC into lower-level DC.

  4. Secondary Rectifiers: Convert the transformed signal into clean DC.

  5. Regulators and Filters: Smooth out voltage to maintain stability.

  6. Fan and Thermal Sensors: Regulate internal temperature.


Types of Power Supplies

1. ATX (current desktop standard)

  • The most common physical format.

  • Versions: ATX 2.3, 2.4, 3.0, and the newer ATX 3.1, which supports 12VHPWR connectors for modern GPUs.

2. SFX / SFX-L

  • Smaller units used in compact PCs (Small Form Factor).

3. Flex-ATX, TFX, etc.

  • Designed for specific case formats or server environments.


Energy Efficiency (80 PLUS Certification)

PSUs are rated by 80 PLUS efficiency certifications, indicating how efficiently they convert power:

CertificationApprox. Efficiency
80 PLUS White80%
80 PLUS Bronze82–85%
80 PLUS Silver85–88%
80 PLUS Gold87–90%
80 PLUS Platinum90–92%
80 PLUS Titanium92–94%


Power Output (Wattage)

The wattage determines how much power the PSU can deliver.

  • Basic PCs: 400–550 W

  • Mid-range gaming: 600–750 W

  • High-end gaming / workstations: 850–1200 W

  • Servers or multi-GPU setups: >1200 W

The most important factor is not just total wattage, but the quality and stability of the 12V rail, which powers the CPU and GPU.

Graphic card

 GRAPHIC CARD

What is a graphics card?

A graphics card (also known as a GPU, or Graphics Processing Unit) is the component responsible for processing and rendering images, videos, and animations on a computer.

It takes the data from the CPU and transforms it into visual information that can be displayed on a monitor.
In simpler terms, it’s what allows you to see everything that appears on your screen — from your desktop background to complex 3D games.

Without a graphics card (or an integrated GPU), a computer would not be able to display images properly.


Types of graphics cards

1. Integrated graphics card

  • Built directly into the CPU or motherboard.

  • Shares the computer’s RAM instead of having its own memory.

  • Common in laptops and office PCs that don’t need high graphical power.

Advantages: cheaper, consumes less power, produces less heat.
Disadvantages: lower performance, not suitable for gaming or heavy 3D tasks.


2. Dedicated graphics card

  • A separate component installed in the PCIe slot of the motherboard.

  • Has its own video memory (VRAM), allowing much better performance.

  • Used for gaming, video editing, 3D design, and artificial intelligence.

Advantages: high performance, better image quality, faster rendering.
Disadvantages: higher cost, consumes more energy, generates more heat.


Main components of a graphics card

  • GPU (Graphics Processing Unit): the core that performs all the visual calculations.

  • VRAM (Video RAM): memory dedicated to storing textures, frames, and visual data.

  • Cooling system: usually includes fans or liquid cooling to prevent overheating.

  • Ports: HDMI, DisplayPort, or DVI to connect monitors.

  • Power connectors: used to supply additional electricity from the power supply.


What is it used for?

  • Gaming: renders 3D graphics in real time with high detail and frame rates.

  • Video editing and design: accelerates rendering and playback of high-resolution content.

  • Artificial intelligence and data processing: modern GPUs can perform parallel computations very efficiently.

  • Virtual reality and 3D modeling: essential for immersive environments and professional applications.

  • General performance improvement: in some systems, the GPU helps speed up non-graphic tasks.




STORAGE DRIVE

 STORAGE DRIVE


What is the storage unit?

The storage unit (also called hard drive, SSD, or simply storage) is the component of the computer where all data is permanently stored.

It stores:

  • The operating system (Windows, Linux, macOS, etc.).

  • Programs and applications.

  • Personal files: documents, photos, music, videos, etc.

  • Temporary files and virtual memory of the system.

In summary, without a storage unit, a PC cannot function, because it would have nowhere to store or load the operating system and programs.


Types of storage units

1. HDD (Hard Disk Drive) – Mechanical hard drive

  • Uses rotating magnetic platters and a reading arm.

  • It is cheaper and has large capacity (1 TB, 2 TB or more).

  • However, it is slower and more fragile to movement.

Advantages: low cost, large capacity.
Disadvantages: slow, generates noise and heat, can be easily damaged.


2. SSD (Solid State Drive) – Solid-state drive

  • Has no moving parts. Uses NAND flash memory, like a USB drive.

  • Much faster, quieter, and more resistant.

  • The price per GB is higher, though it is becoming more affordable.

Advantages: fast system startup, better overall performance.
Disadvantages: lower capacity for the same price, limited wear (though in practice they last for years).


3. SSHD (Solid State Hybrid Drive) – Hybrid drive

  • Combines an HDD with a small SSD section.

  • The most frequently used files are stored in the SSD part to speed up access.

Advantages: balance between speed and capacity.
Disadvantages: not as fast as a full SSD.


4. NVMe / M.2 SSD

  • A more advanced version of the SSD that uses the PCIe bus instead of SATA.

  • Much faster (up to 10 times faster than a SATA SSD).

  • Connects directly to the motherboard through an M.2 slot.

Advantages: extreme speed, compact size.
Disadvantages: higher price, requires a compatible motherboard.

Memory RAM

 MEMORY   RAM.


What is RAM Memory

RAM (short for Random Access Memory) is a type of volatile memory in a computer.
This means it loses all stored information when the system is turned off.

RAM temporarily stores the data and programs that the CPU needs to use immediately.
The more RAM a system has, the more tasks it can perform simultaneously and the faster it operates.


Main Functions of RAM

  1. Temporary storage of active data
    Stores the data being used or processed by the operating system, applications, and ongoing processes.
    For example, when you open a web browser, its data is loaded into RAM for faster access.

  2. Support for the CPU (processor)
    RAM acts as an intermediary between the storage (hard drive or SSD) and the CPU.
    The CPU is extremely fast, but it cannot wait for data to arrive from a slower hard drive; therefore, RAM serves as a high-speed workspace.

  3. Program execution and multitasking
    Allows multiple programs to run simultaneously.
    If RAM becomes full, the system uses “virtual memory” (part of the hard drive), which is slower.

  4. Cache and buffers
    RAM is also used as a buffer or cache for temporary operations, such as video editing or loading textures in a game.


Types of RAM

1. DRAM (Dynamic RAM)

The most common type of RAM in computers.
Stores each bit of information in a capacitor that must be refreshed constantly.
Examples: DDR4, DDR5.

2. SRAM (Static RAM)

Faster but much more expensive.
Used as the processor’s cache memory (not as main RAM).
Does not need constant refreshing.

3. VRAM (Video RAM)

Memory dedicated to graphics cards (GPUs).
Stores textures, shadows, and other graphical data.

4. LPDDR (Low Power DDR)

A low-power version used in laptops, tablets, and smartphones.


Importance of Having Enough RAM

  • Higher speed: reduces the use of virtual memory, which is slower.

  • Better multitasking: allows more programs to run at the same time.

  • Optimized performance: modern games and design software require a large amount of memory.

  • System stability: prevents crashes or slowdowns due to lack of temporary space.

 THE PROCESSOR (CPU)



 What Is a Processor (CPU)?

CPU stands for Central Processing Unit.

It is the brain of the computer or electronic device, responsible for executing program instructions and coordinating the operation of all other system components (memory, storage, graphics, etc.).

 What Is the Purpose of the CPU?

The CPU is responsible for processing data and instructions.

In simple terms, everything a computer does passes through the CPU.

Examples of what it does:


 Runs programs (for example, a browser, game, or word processor).

Controls peripherals (keyboard, mouse, screen, etc.).

 Manages mathematical and logical operations.

 Coordinates the flow of information between memory, the GPU, the hard drive, and other components.

 Main Components of a CPU


1. Control Unit (CU)

   Directs and coordinates all system operations. It interprets program instructions and tells the rest of the components what to do.


2. Arithmetic Logic Unit (ALU)

   Performs mathematical operations (addition, subtraction, multiplication, division) and logical operations (comparisons, decisions).

3. Registers

   Small memory areas inside the processor that store temporary data, such as numbers used in operations or memory addresses.

4. Cache

   An ultra-fast memory built into the processor. It stores frequently used data to speed up access (levels L1, L2, and L3).

5. Buses

   Channels that connect the CPU with memory and other system components.


 How It Works

The operation can be summarized in the instruction cycle:

1. Fetch The CPU retrieves the instruction from RAM.

2. Decode It interprets the instruction.

3. Execute It performs the operation (for example, an addition).

4. Store It saves the result if necessary.

This happens millions or even billions of times per second.


 CPU Performance

Performance is mainly measured by:

Clock speed (GHz): number of cycles per second (1 GHz = one billion cycles).

Number of cores: each core can execute tasks independently.

Threads: virtual divisions of each core (for example, Intel’s Hyper-Threading or AMD’s SMT).

Cache: more cache means faster access to frequently used data.

Architecture: internal design (for example, x86, ARM, RISC-V).

Power consumption and temperature: energy efficiency and heat dissipation.


 Types of CPUs

1. General-purpose CPUs (used in PCs, laptops, servers).

2. Low-power CPUs (used in phones, tablets, IoT devices — often ARM-based).

3. High-performance CPUs (used in servers, workstations, supercomputers).

4. Integrated CPUs (SoC - System on Chip): combine CPU, GPU, RAM, and other components in a single chip (e.g., Apple M1/M2, Snapdragon, etc.).
