How To Build A Computer Definition

Determine your computer’s use. Before you buy any components or establish a budget, you’ll need to know what you plan on using to build a computer.

Standard desktop PCs used for browsing and minor programs (e.g., Microsoft Word and Excel) can use older, less expensive parts.
While gaming- or editing-focused computers will need more robust, up-to-date details.

You can expect to spend under $500 for most basic desktops. How to build a computer Gaming and editing computers may run you anywhere.

Establish a budget:

  • It’s too easy to start buying attractive parts without sticking to a budget, only to realize that you’re out of money and don’t have all of the necessary equipment to build your PC. Figure out a soft limit (e.g., $300) and a hard limit (e.g., $400) and try to stay within that range.
  • Common sense should guide your purchasing as well. For example, if the processor for which your budget is $100 but a more excellent, newer model is discounted from $200 to $120 at your local tech store, spending the extra $20 is probably a better long-term investment.

Which components you need to buy?

Processor :

  • Acts as the “brain” of your computer.

Motherboard:

  • Serves as an interface between all of your computer’s components and the processor.

RAM:

  • Random Access Memory. More RAM will provide more “workspace” to increase your computer’s performance. Think about the RAM as a table: more RAM gives you more room for doing things on that table. Less RAM is like having a smaller table.

Hard drive and stores data:

  • You can buy a traditional hard drive, or you can opt for a more expensive solid-state drive (SSD) if you want a high-speed drive.

Power supply:

  • Powers all of your computer’s separate components. The power supply is also the interface between your computer and the wall socket into which you plug your computer.

Case:

  • Necessary for storing and cooling your components.

Graphics card:

  • You are used to rendering images on your computer. While most processors have a built-in graphics processing unit (GPU), you can buy a dedicated graphics card if you plan on gaming or using your computer for intensive editing.

Cooling system:

  • Keeps the inside of your case at a safe temperature. Only necessary for gaming and editing PCs—regular PCs should be fine with a stock cooler.

Purchasing Components

In-store locations such as Best Buy will stock computer components, but you can usually find comparable parts for cheaper if you shop online. Common online areas include Amazon, eBay, and NewEgg.

Don’t write off used parts, especially if the details are listed as “Like New” or are in new condition. You can often buy such parts at a heavily discounted price for little to no change in function.

Research every component you intend to purchase. Read magazines and online consumer review sites for more information. Remember, this is one of the most critical steps  to build a computer because everything will depend on your hardware working correctly.

A few relevant articles on wikiHow include How to Build a Computer, How to Choose Components for Building a Computer and Build a Powerful Quiet Computer.

Look for good reviews for your preferred product, both on the site you’re considering purchasing it and elsewhere. Stay away from marketing graphs or numbers – there is always some trickery to make the numbers seem better than they are. Some reputable hardware reviewers are Linus Tech Tips, Tom’s Hardware, or Gamers Nexus.

Once you’ve found a decently reviewed component, look for negative reviews of the member. You may find that the feature is great for specific uses but inappropriate for your preferences.

Find a processor:

  • The processor (or CPU) is the core of your computer’s performance. The higher the processor’s speed in gigahertz (GHz), the faster it can process data. Many applications use multiple threads at the same time so that more cores can improve performance.

what will be the Processor of  budget?

Processors typically come in quad-core, hexa-core or higher. Unless you’re building an ultra-high-performance gaming PC, you should stick to <6 cores.
Intel and AMD are two of the leading processor manufacturers. Typically, AMD offers better value.
Get a motherboard that fits your processor. You’ll want to select a motherboard that is compatible with your processor, which can be talented by checking the socket of the CPU and motherboard.
“Onboard Wi-Fi” (ensures that your computer will have wireless capabilities)
Bluetooth
Multiple RAM slots
Support for graphics cards if necessary (PCIe x16 slot).

Purchase RAM:

  • RAM is responsible for storing data from running programs, so having enough of it is essential. Before buying RAM, check both your processor and your motherboard for the type of RAM, which is supported.
  • There is a limit to how much RAM your computer can use, and that limit is dictating by your processor’s capabilities (typically 64GB) and your applications.
  • If a program stores only 1GB data in the RAM, more RAM won’t accelerate the task. Typically 8 GB is encouraged, with higher-end gaming machines benefiting from 16GB.
  • Depending on your motherboard, you’ll usually buy either DDR3 RAM or DDR4 RAM. The type of RAM that is supported by your motherboard will be noticing in the motherboard’s documentation.

Buy a hard drive:

  • Comparatively speaking, purchasing a hard drive is easy—most hard drives are compatible with virtually all motherboards and processors, though you may need to make sure the hard drive you find will fit your case. You’ll want to buy a SATA hard drive that stores at least 500 gigabytes and be sure to buy from a reputable manufacturer such as Western Digital, Seagate, or Toshiba.
  • Your average hard drive has a speed of 7200 RPM.
  • Hard drives can also use IDE instead of SATA as their connections, but SATA is newer and supported on all modern motherboards.
  • If you want a smaller hard drive with faster data retrieval, you can instead purchase a solid-state drive (SSD). These drives are significantly more expensive than most standard computer hard drives. Often they are used as a complementary drive with a larger hard drive.
  • SSDs usually come with a SATA connector, with newer models using NVMe M.2 or SATA M.2. Some motherboards might not support the NVMe or M.2 standard.

Purchase a graphics card:

  • A dedicated graphics card is essential for playing the latest games, but not a significant issue for a computer you plan on using for daily tasks. If you watch or edit a lot of HD video or play many games, you’ll want a dedicated graphics card.
  • As with any other component, make sure that your graphics card is compatible with your motherboard. However, you are unlikely to get issues.
  • The graphics card should take up 1/3 of a gaming computer budget.
  • Nearly all Intel CPUs have integrated graphics, so you don’t need a dedicated card if you’re planning to use the computer for office work, web browsing email, and a little bit of online gaming. AMD also manufactures the 2200G and 2400G processors with powerful integrated graphics, capable of some games at lower settings.
  • Graphics cards are also referring to as “video cards” or “GPU.”

power supply:

  • The power supply powers all of your components in your computer. Some cases come with a power supply already installed, but others require you to provide your own.
  • The power supply should be powerful enough to charge all of your components; don’t worry about it being so powerful that you waste electricity by powering more than you need, as it will only output as many watts as you use. The number on its wattage is only its max capacity.
  • Pick up a case that is both functional and easy on the eyes. The point is, what holds your computer components.
  • A few cases come with a power supply included, but if you are making gaming build, then getting a separate power supply is recommended, as the power supplies that come with cases are usually not very high quality.
  • The size of the case will be finishing on how many drives bays and card slots it has and the size and type of your motherboard.
  • Be sure to select a case that can fit all of your components, including your hard drive.
  • Cases might obstruct airflow, causing some higher-end components with more massive power draw to overheat.
