I'm planning to build a gaming PC, but I'm completely new to computer hardware and want to make sure I don't forget anything important. I currently plan to buy a CPU, motherboard, graphics card, RAM, storage, and a case. Besides a keyboard, mouse, and monitor, what other components or accessories will I need, and what should I do first to make sure everything is compatible?

Before assembling the computer, read a few beginner build guides and watch complete build tutorials. They’ll show where each cable goes and how to install the motherboard, cooler, storage, and graphics card without rushing. Make a checklist first, then confirm that every part is compatible before purchasing.
The main parts you’re missing are a power supply and a CPU cooler. Some CPUs include a cooler, but you’ll need to check before buying one separately. You may also want extra case fans, thermal paste if it isn’t pre-applied, and an operating system.
Use a compatibility-checking parts list tool before ordering anything. It can catch issues such as the motherboard not supporting the CPU, insufficient power supply wattage, RAM compatibility, or the graphics card being too large for the case. It’s also worth adding a headset or speakers if you need audio.
