Learn about every component that makes a PC work
PC Case
The chassis that houses all components with proper airflow design.
- • Good airflow prevents overheating
- • Cases come in various sizes: Mini-ITX, ATX, Full Tower
- • Cable management improves cooling
Start by placing the Case on the workbench.
Motherboard
The main circuit board connecting all parts with power delivery.
- • Contains the chipset that manages data flow
- • Socket type must match CPU
- • Different sizes: ATX, Micro-ATX, Mini-ITX
Install the Motherboard into the Case using standoffs.
CPU (Processor)
The brain executing billions of calculations per second.
- • Modern CPUs have billions of transistors
- • Clock speed measured in GHz
- • More cores = better multitasking
Gently place the CPU into the socket - align the golden triangle.
Thermal Paste
Thermal compound filling microscopic gaps for optimal heat transfer.
- • Improves heat conductivity by 10-20°C
- • Should be reapplied every 2-3 years
- • Too much can insulate instead of cool
Apply a pea-sized amount to the center of the CPU.
CPU Cooler
Active cooling system maintaining optimal CPU temperatures.
- • Air coolers vs Liquid coolers
- • Larger heatsinks = better cooling
- • Fan speed affects noise and cooling
Mount the Cooler on top of the CPU and thermal paste.
RAM (Memory)
Fast, temporary storage for active data and programs.
- • DDR4 vs DDR5 - newer is faster
- • Dual-channel doubles bandwidth
- • More RAM = more apps running smoothly
Snap RAM sticks into the vertical slots until they click.
Graphics Card
Specialized processor rendering graphics and accelerating AI tasks.
- • Has its own RAM (VRAM)
- • Essential for gaming and 3D work
- • Ray tracing creates realistic lighting
Insert the GPU into the PCIe x16 slot.
NVMe SSD
Permanent storage for OS and files with lightning speed.
- • Up to 7000 MB/s read speeds
- • No moving parts = silent & reliable
- • NVMe is 5x faster than SATA SSDs
Screw the SSD into the M.2 slot on the motherboard.
Power Supply
Converts AC wall power to stable DC power for components.
- • 80+ rating indicates efficiency
- • Modular PSUs reduce cable clutter
- • Wattage should exceed total system power
Slide the PSU into the bottom bay with fan facing down.
