I'm planning to build a gaming PC, but I'm completely new to PC hardware and don't really know what else I need. So far, I'm planning to buy a CPU, motherboard, graphics card, RAM, storage, and a case. Aside from peripherals like a keyboard, mouse, and monitor, what components or supplies am I missing, and what should I do next to make sure everything is compatible?

The big things you’re missing are a power supply and a CPU cooler. Depending on the case and cooler, you may also need extra case fans and thermal paste. Make sure the PSU has enough wattage and the right connectors for your graphics card.
Use a compatibility-checking build tool to select your parts together. It can flag issues such as the motherboard socket not matching the CPU, insufficient power, or a cooler not fitting the case. You’ll also need an operating system, and possibly a USB drive to install it.
Before buying everything, watch a few complete PC-building tutorials and read beginner guides. They’ll show the installation order and help you avoid common mistakes. A typical checklist is CPU, motherboard, GPU, RAM, storage, case, PSU, CPU cooler, case fans, and an operating-system installer.
