What Do I Need to Set up a Desktop Computer?

There are two basic options when choosing a new desktop computer: an all-in-one computer, which combines all the necessary hardware into a single unit, or, a desktop tower with a separate monitor and other components. Since an all-in-one computer packs everything into one sleek design, we will be focusing on the latter. Here are the essential items you’ll need when setting up a new desktop computer:

• Desktop tower. The main unit housing your computer's processor, storage and other key components, a desktop tower is essentially the brains of your computer. Its upright design allows for easy access to internal components like the processor, memory, storage and graphics card, making upgrades and repairs more straightforward.
• Monitor. Computer monitors come in various sizes, resolutions and technologies, ranging from basic models for everyday tasks to high-performance displays for gaming, graphic design or video editing. Key features to consider include resolution (such as Full HD, 4K or 5K), refresh rate and color accuracy.
• Keyboard and mouse. Providing precise control and efficient navigation, mice and keyboards are important devices for any computer. Keyboards come in various styles, from compact and membrane-based to mechanical versions favored by gamers and typists for their tactile feedback. Mice also vary in design, with ergonomic shapes, wireless options and features like customizable buttons or high-precision sensors for gamers and professionals alike.
• Power cables. Power cables provide the electrical connection between your desktop tower, monitor and other devices to a power source. Typically durable and insulated, they keep a steady and safe flow of electricity to keep your system running smoothly.
• Video cables. Transmitting visual data from your computer’s graphics card to your monitor, video cables ensure high-quality display output. Common types include HDMI, DisplayPort, DVI and VGA, each offering different levels of resolution and refresh rates.
• Speakers or headphones. If your monitor doesn't have built-in speakers, external audio devices will be necessary. Speakers offer immersive, room-filling sound, perfect for watching movies, listening to music or gaming, while headphones provide a more private, focused audio experience with added noise isolation.

When gathering all of the components before setting up a home computer, it’s also a good idea to invest in a surge protector or power strip to safeguard your equipment from power surges and ensure there are enough outlets for all components. And, if you haven’t already set it up, an internet connection is necessary for downloading updates, accessing cloud services and staying connected. 

Setting up a new PC is a straightforward process, but you might still be wondering how to set up a new computer. To help ensure that your computer set up goes as smoothly as possible, here is a step-by-step guide on how to set up a new desktop computer:

• Unbox and inspect the components. When you are taking your new computer out of the box, check for any visible damage and verify all components are included.
• Position your desktop tower. Place the tower in a well-ventilated area with easy access to power outlets and enough space for cables.
• Connect the monitor. Use a video cable to connect your monitor to the desktop tower.
• Attach the keyboard and mouse. Plug in the USB or wireless receiver for your keyboard and mouse.
• Connect the power cables. Ideally through a surge protector, plug in the power cables for both the desktop tower and monitor to a power source.

Once you’ve completed these steps and have connected the necessary components, you can power up the system by turning on the desktop tower and monitor. Then, you can finish your desktop set up by completing these final steps:

• Follow on-screen set up instructions. Once powered on, follow the prompts to set up your operating system, configure settings and connect to the internet.
• Install necessary drivers and software. Install drivers for your hardware and any essential software for your needs, like antivirus and security software or gaming platforms.
• Test peripherals. Doublecheck that your keyboard, mouse, speakers and other connected devices are working properly.

If you’ve just finished setting up a gaming PC, you’re going to want to enhance your gaming with a high-performance mechanical keyboard and a responsive gaming mouse with customizable buttons. A comfortable headset with surround sound is also recommended after the PC gaming set up process is complete. This is because PC setups for gaming greatly benefit from having immersive sound and precise input.

You may also want to invest in a gaming chair for better ergonomics during long sessions and consider external accessories like a PC gaming controller or a custom mousepad for better precision. Additionally, cooling solutions such as extra case fans or liquid cooling can help keep your system running smoothly, while RGB lighting adds a personalized aesthetic to help create the best gaming PC setup for you.
