Computer Components & Parts

Build Your Own Custom Rig from Computer Components

When you're building a custom computer from the ground up, be sure to select the best computer components to help you achieve your goal. At Walmart Canada, we carry a wide variety of computer parts - everything from cooling fans to graphics cards, memory upgrades and CPUs so you can build your ideal productivity machine.

Essential Computer Components: The Case

When building your own computer, start by selecting a computer case or tower that suits your needs. Make sure it has enough bays to hold your hard drives, and consider its interior size too. It should have enough room to hold your graphics card, motherboard and any fans you plan to install.
Many choices, such as those from Cougar, offer RGB lighting effects and see-through panels, so you can show off your new computer components. Choose a case that's sleek and compact for tight spaces, yet large enough for your components and future upgrades.

Computer Power Supplies

Another essential item on your short list of computer components is the power supply. Before you choose the one you need, figure out how much power is necessary to run the computer you're building. Focus on the power draw benchmarks produced by the CPU and GPU to help you figure out a minimum total wattage rating, and go from there. Look for models with high-efficiency features, which try to balance performance and energy consumption, and be sure to prioritize quiet fans -- you don't want to be bothered by the sound of a humming power supply when you're trying to concentrate on a game.

Selecting a Motherboard

The motherboard of your homebuilt computer has essential components installed. It's the printed circuit board that contains your computer's principal components, including the processor, memory and connectors where other circuit boards can be slotted. 
Some motherboard options, such as the ROG Strix from ASUS or Z-Series motherboards from MSI, are optimized for gaming applications: they have slots for adding memory, plenty of USB ports for plugging in peripherals, including controllers, keyboards and mice, and some have fun RGB colour effects.

Cooling Mechanisms

Cooling is a big consideration when it comes to building your own computer. Processors and graphics cards can get hot when they're working hard, and oftentimes external fans and heatsinks are needed to help manage the internal temperatures of your system. Choose models that are brightly coloured for showing them off through see-through panels on your case, or opt for smaller brushless versions that are designed to move a lot of air through a small space. Noise is a consideration here too; make sure to choose one that operates quietly.
Heat sinks are another popular cooling mechanism that are typically installed directly on the circuit board. They don't require any power; instead, they operate passively by dissipating heat away from your computer. Sometimes they're used in conjunction with fans to optimize its cooling capability.

Graphics Cards

If you game as a hobby, then you know how important graphics cards are to your setup. Graphics cards help ensure that 3D images and video are rendered smoothly and quickly, so as to not slow your gameplay, especially when you're playing something graphically intense with plenty of explosions or fast-paced action. Graphics cards also make light and shadow areas look realistic and help bring your favourite titles to life.
When selecting a new graphics card for your build, be sure to choose one that has enough memory to support the games you most want to play. Pay attention to specs such as memory size and GPU processor speed. Also note the kind of visual inputs it supports, usually HDMI or DisplayPort.

And if you're not a gamer, you'll want to get at least a basic graphics card for  watching movies and browsing the web, unless you have onboard graphics built into the motherboard.

More Essential Computer Parts: CPUs and Memory

Your computer's CPU is the "brains" of the operation -- it's in charge of controlling everything your computer does, and it's responsible for how fast programs load and operate. AMD and Intel are two of the most popular brands on the market, and you can find both at Walmart Canada.
Memory, or RAM, allows you to multitask when using your homebuilt computer. The amount you should purchase depends on what your needs are. If you're using it for light office work, then 8GB or 16GB may be enough. For more intense gaming, you'll likely want as much as 32 or 64GB to ensure you can run the latest AAA titles without bogging down your system.
