When most people think about building a new PC or upgrading their existing ones, they focus on the obvious stuff, like a faster CPU, a more powerful GPU, and sometimes even a high refresh rate monitor for gaming. Sure, it makes sense, since these parts are responsible for delivering the raw performance you expect while upgrading a PC. However, your day-to-day experience when you sit in front of your PC can depend just as much on the peripherals and accessories you use.

If you allocate your entire budget to what's inside your case, you may end up hurting your experience in the long run. A flimsy chair or a wobbly monitor stand may not seem like a big deal at first, but trust me, the discomfort and frustration will creep up on you. Eventually, you may regret not spending a couple of hundred dollars on the parts of your desk setup you interact with the most. That's why it's worth taking a closer look at the accessories most people overlook when splurging on their rigs.

A fully-adjustable monitor arm

It helps you position your monitor exactly how you want

A monitor arm might seem like a luxury, but it's one of the few PC accessories that I never knew I needed until I actually started using one. Most monitors come with a built-in stand, but they're rarely designed with ergonomics in mind. In most cases, you're limited to adjusting the tilt, while some expensive models offer height and swivel adjustments. Even then, the range of motion is limited. My biggest issue with included stands, especially when it comes to gaming monitors, is that they take up too much desk space. That's precious space I could use to move my mouse around more freely or angle my keyboard the way I like.

With a fully adjustable monitor arm, you not only reclaim all that space but also get far more freedom of movement. You can pull your monitor closer when you want to focus while playing competitive first-person shooters like I do, raise it to improve posture during long work sessions, and even fully rotate it when you want to use it as a secondary monitor. It's a small investment that makes your desk setup more flexible for your daily needs. Once you use one, it's hard to go back to the bulky stands included with monitors.

An ergonomic chair

Prioritize comfort, and your back will thank you later

I can't stress just how important it is to invest in a good chair, especially if you sit in front of your PC for several hours a day like I do. Too many people treat the chair as an afterthought while building or upgrading their PC setups, often settling for budget office chairs or flashy "gaming chairs" that don't offer proper back support. I used a Corsair gaming chair for a few years before I decided to splurge on the Haworth Fern. At roughly $1,300, it's definitely expensive, but I believe it's an investment that will pay off in the long run.

For starters, a high-quality ergonomic chair immediately makes you feel more comfortable when you're at your desk, with breathable materials and proper lumbar support that aligns with your spine's natural curve. This helps you avoid posture-related problems and reduces the strain on your lower back during long work or gaming sessions. In fact, my posture has improved since I started using the Haworth Fern a year ago. You'll also typically get fully adjustable seats and armrests, allowing you to align the chair with your desk height. Once you've used one that truly fits your body, you won't regret paying the premium price.

A large desk mat

It's more than just a huge mousepad

You might think a desk mat is just a cosmetic addition, but it can actually make a big difference in how comfortable and organized your setup feels. While a standard mousepad gives you enough space for tracking your mouse, a desk mat brings a lot more to the table. Since it covers a significant portion of your desk, your mouse, keyboard, and wrists sit on a consistent surface, which not only improves tracking accuracy while gaming but also provides a smoother feel as you move your hands across the desk.

The benefits of using a desk mat over a traditional mousepad go beyond just comfort. For instance, if your desk is made of soft wood or has a laminated surface, a large desk mat will protect it from scratches, dents, and even accidental spills if you're someone who eats at your desk like I do. Most desk mats also have a non-slip base, so your keyboard and mouse stay firmly in place when you're sweating in competitive games. I've been using the Glorious 3XL extended gaming mouse pad for several years, and I don't think I'll be going back to a standard mousepad anytime soon.

A high-capacity UPS

It gives you enough time to save all your work during an outage

Considering most modern PSUs have built-in surge protection, you may wonder if a UPS is really necessary. The thing is, a PSU's surge protection is only designed to handle small voltage spikes, not large surges from severe lightning strikes. A UPS not only handles large voltage spikes, but also gives you battery backup to save all your work and safely shut down your system during a power outage. So, if you live in an area with frequent storms or unstable electricity, it's still worth the investment.

More importantly, a high-quality UPS will smooth out voltage fluctuations that can slowly damage sensitive components in your PSU over time. So, if you want to preserve the lifespan of your PSU, a UPS can serve as an extra layer of protection. I highly recommend spending more on a UPS with a higher VA rating because it'll give you longer battery life to power all your components, including your monitors and Wi-Fi router. This helps you stay online and continue working uninterrupted in case of short outages.

Your PC setup is more than what’s inside the case

It's easy to get caught up in chasing the latest and most powerful components for your build. But once you actually start using your high-end PC, you'll quickly realize that your experience depends just as much on the peripherals and accessories outside your case. A poorly positioned monitor can cause neck strain, an uncomfortable chair can ruin your posture, and an abrupt power outage can cost you hours of unsaved work. These accessories can directly affect how much you enjoy using your PC every day. So why cut corners and pay the price later?
