What you need to build a gaming PC

Quick Scoop: You need a CPU, GPU, motherboard, RAM, storage, power supply, cooling, case, and usually a monitor plus keyboard/mouse to make it usable. A current build guide also notes that a Phillips #2 screwdriver, a table or other large workspace, and care against static electricity are important when assembling the parts.

Part	What it does	Why it matters
CPU	Handles general processing	Affects game performance, especially in CPU-heavy titles
GPU	Renders the graphics	The most important part for gaming performance in modern builds
Motherboard	Connects all components	Must match your CPU socket and support your parts
RAM	Short-term working memory	Helps with smooth gameplay and multitasking
Storage	Holds games and files	An SSD is the usual choice for fast loading; HDDs are optional for extra cheap space
Power supply	Provides power to everything	Needs enough wattage and good quality for reliability
Cooling	Keeps the CPU and case cool	Prevents overheating and maintains performance
Case	Holds the build	Must fit your motherboard and GPU, and allow airflow

Also needed

• Operating system. Most gaming PCs use Windows, though Linux is an option for some users.
