A power supply and monitors are two key components that no gaming PC can survive without. No PC power supply means, well, no power. And without any monitors, you won’t be able to create new content or watch yourself crush your favorite game. 

Because these PC components are so essential, they’re often overlooked. But not anymore. Here’s why the power supply and monitors that you purchase matter. 

Power Supply

This may seem unimportant, but when it comes to buying a power supply for your PC you do need to think about a few things. The general rule of thumb is to look up the power requirements for the other parts in your PC, plug them into a calculator and purchase 30% more wattage than is required. 

According to some basic estimates, you should have about 500 to 650 watts for eSports, about 750 to 850 watts for AAA gaming and at least 850 to 1200 or more watts for content creation. It’s important to never settle for a cheap power supply – if your power supply fails, your entire PC will fail as well. Let’s make sure that never happens, right?


Once you’ve built your PC, it is important to purchase a monitor that’s the best fit for your specs. The first aspect of a monitor you’ll want to look at is the resolution. It is generally recommended to buy 1080p for entry-level gaming or eSports and 1440p or 4K, based on your preferences and budget for any higher-end tasks. 

Another important aspect of a monitor is its screen size. It’s important to get a high enough resolution for the size of the monitor you’re using. If the resolution is too low for the screen size, the image will be pixelated as opposed to sharp and crisp. For 1080p graphics, you’re going to want a screen that is less than 27-inches so that it does not stretch the image. For 1440p and 4K, you will need a screen that is 27-inches or larger. 

There’s a lesser-known distinction between two different types of monitors: IPS and TN. IPS monitors tend to be more color-accurate and have better viewing angles. That’s why they’re recommended for content creation. TN monitors are fast and typically less expensive, so they are recommended for gaming. For those interested in AAA gaming, the type of monitor you purchase just comes down to preference. See, knowing which PC user you are comes in clutch. 

The refresh rate is a metric that depicts how many frames you can see on the monitor per second. When making your purchase, ensure your monitor of choice has a high refresh rate so that gameplay will be smoother.
