Tech Concepts + Product/Build Features Covered (PC Parts + Assembly Guide)

Computer Parts Overview

The tutorial first introduces basic external components—monitor, keyboard, and mouse, along with the CPU—then focuses on internal CPU cabinet components, including:

  • SMPS / Power Supply
  • CD-ROM / CD drive
  • SATA cables
  • RAM
  • Hard disk
  • Motherboard
  • Processor (CPU)
  • CPU fan

SMPS (Power Supply) Types and Connectors

The guide explains the difference between:

  • AT power supply
    • Typically described as having two 12-pin connectors
  • ATX power supply
    • Uses 20-pin or 24-pin main connectors
    • The tutorial specifically shows:
      • A 24-pin main connector
      • Plus an additional 4-pin connector for the motherboard

The SMPS provides power to storage drives such as:

  • Hard disk
  • CD-ROM It also references older storage media (e.g., floppy/CD historically), implying these are not common in modern builds.

Motherboard Layout: Key Ports and Slots

Key motherboard components and interfaces covered include:

  • RAM slots (2 slots) for installing DDR RAM
  • CPU socket/lock area where the processor is installed
  • Video outputs
    • HDMI
    • VGA (for monitor connection)
  • Connectivity
    • USB ports (multiple)
    • LAN port (RJ45) for internet
    • Audio jacks (audio in, audio out, and mic—described as multiple audio connectors)
  • Expansion / legacy
    • PCI slots
  • Storage interfaces
    • SATA slots for connecting SATA data cables
  • CMOS battery
    • Maintains date/time even when the PC is turned off

Cabling Concepts: Data vs. Power

The tutorial contrasts two kinds of connections:

  • SATA data cables
    • Used for data transfer between the motherboard and drives
  • SATA power connectors
    • Drives also require separate power from the SMPS

It also contrasts older setups using IDE cables with newer SATA connections.

Drive Installation Details

The build includes mounting steps for drives:

  • CD-ROM / CD drive
    • Mounted in the front bay/slot
    • Secured with screws on both sides
  • Hard disk
    • Placed in the drive bay
    • Secured with screws after placement

For each drive, the tutorial emphasizes connecting:

  • SATA power
  • SATA data

CPU Installation and Cooling

  • CPU installation
    • Uses a socket lock:
      1. Open lock
      2. Place CPU
      3. Close lock
  • CPU fan
    • Sits above the processor
    • Receives power through the motherboard fan header (fan power connection shown)

Front Panel Wiring

The guide connects front panel connectors to the motherboard, including:

  • USB front ports
  • Audio front panel
  • Power switch / restart buttons
  • LEDs / indicator connections (described generally as LED/power cables)

Step-by-Step Build Order (Process Summary)

  1. Install SMPS into the cabinet and screw it in.
  2. Install CD-ROM (if available) and screw it on both sides.
  3. Install hard disk and screw it in place.
  4. Install CPU (processor) using the socket lock.
  5. Install RAM (DDR RAM) into the RAM slots; press until the locks engage.
  6. Mount the motherboard into the cabinet using screws.
  7. Connect motherboard power:
    • ATX 24-pin + 4-pin
  8. Connect power to the hard disk + CD drive.
  9. Connect SATA data cables (motherboard ↔ drives).
  10. Install and power the CPU fan.
  11. Connect front panel cables (USB/audio/buttons/LEDs).
  12. Close the case.
  13. Connect peripherals:
    • Power cord
    • Monitor via VGA
    • Keyboard/mouse via USB
  14. Power on and verify boot/login.
