Unless you have spare parts at your disposal, you need to consider seven core components when putting together a build: a case, a motherboard, a power supply, a CPU, a graphics card (or two), some RAM, and storage. And you'll see almost infinite options out there for each of these.
What are the 6 main parts needed to build a PC?
The basic components of a PC are the case, central processing unit (CPUcentral processing unit (CPUA central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program.https://en.wikipedia.org › wiki › Central_processing_unitCentral processing unit - Wikipedia), power supply unitpower supply unitThe efficiency of a computer power supply is its output power divided by its input power; the remaining input power is converted into heat. For instance, a 600-watt power supply with 60% efficiency running at full load would draw 1000 W from the mains and would therefore waste 400 W as heat.https://en.wikipedia.org › wiki › 80_Plus80 Plus - Wikipedia (PSU), motherboard, random access memory (RAM), graphical processing unit (GPU), and storage (either a hard drive or solid state drive).May 9, 2019
If you're building a computer to browse the internet, you can spend as little as $300. If you're looking to build a gaming computer, prices will vary greatly—$1000 is a good place to start for a budget build. Anything in between can vary greatly, all the way up to $4000 or higher.
