What to Look For in a most powerful all in one pc?

Some of you may be reluctant to select one of the most powerful all in one pc, to be honest. The main reason is that you didn’t study that before. There are pretty lots of factors that must be considered when investing in most powerful all in one pc. You are expected to count on our expertise in most powerful all in one pc to make the right choice. 

So now we move on to the significant factors related to most powerful all in one pc you must keep in mind:

Monitor Size

It's important to know the size of the monitor you need to purchase in order to fit your specific needs as a desktop computer user. Monitor sizes go as low as 19 inches and up to 34 inches wide. The recommended and most popular size comes anywhere between 23 - 27 inches wide. These sizes are perfect for those users who need to write up documents, search the web, or maybe stream some movies.

Graphics Cards

For most users, the graphics cards that come with any of the best desktop computers will be fine. But gamers and creative professionals will want to spend a little extra to upgrade in this area. While a graphics card like an NVIDIA GeForce GTX 1650 is a fine choice, jumping up to an GeForce RTX 2060 or 2080 will make a huge difference in what you can do with your computer.


Depending on the desktop model you are looking at, some desktop towers do not include a sound card or speakers. In this case, external speakers will be necessary if you plan on watching or listening to anything with audio. However, if you do not plan on doing any of these activities frequently (or at all in some cases) then the basic speaker system built-in with most computers and their corresponding monitors will work just fine.


For most people, choosing between a hard drive (HDD) or solid state drive (SDD) will be a matter of preference when it comes to the best desktop computers. While hard drives are slower and more prone to failure, they offer more storage for the money. SSDs may be more costly, but their speed and reliability often makes them a great choice for gamers and video editors trying to squeeze every last ounce of performance out of their machines.


A powerful CPU sets the standard for the overall speed and capability of your computer. As a baseline, you should want a computer with at least a 10th Generation Intel Core i3 or AMD Ryzen 3 CPU. Ideally, you’ll want a desktop computer with an 11th Generation Intel Core i5 CPU (or an AMD Ryzen 5 CPU) if you’re a gamer or a creative professional (photographer, illustrator, video editor, etc.). If you’re on a budget, a computer with a 8th Generation Intel Core i3 or AMD Ryzen 3 CPU will do the trick.


If you’re looking for a computer that will last you more than a few years, you’ll want to buy a desktop computer that is fixable, upgradable and/or expandable. This means that you’ll be able to open up the case of your tower and access the hard drive/SSD, GPU, RAM and optical drive. Generally speaking, components such as the CPU, motherboard and power supply are not upgradable in pre-configured computers.


Internal storage devices aren’t the only way to store or access files. Like any computer, desktop PCs come with a plethora of ports that provide you with plenty of expansive options, including external storage.


Desktop computers come with a lot of memory, which is specifically for apps to run while they’re in use. Working together with the CPU, more memory enables demanding apps to run as fast as possible, or many apps to run at the same time. At minimum, you’ll want to buy a desktop computer with 4GB of RAM, but 8GB of RAM is preferable. This will ensure that your computer can handle everything from web browsing productivity software 4K video and even some light photo and video editing. For dedicated gamers, streamers and creative professionals, 16GB of RAM is more desirable.


Will A Desktop Computer Be Able To Connect To The Internet Wirelessly?

If you are looking to connect your desktop computer to the internet wirelessly, make sure that the computer is purchased from Micro Center. If the computer is not purchased from Micro Center, check the packaging or the product manual for any information regarding wireless technology. If your computer does not support wireless, you may be able to install a wireless network card or wireless network adapter to achieve connectivity.

Which Version Of Microsoft Office Is Included With Windows 10?

Most commonly, the Microsoft Office that comes on the computer will be a trial version of Microsoft Office 365 which is a subscription-based service of Microsoft Office. When the trial period is complete, you would need to subscribe or purchase another version of Office to continue using the product.

What's The Point Of Using The Computer For?

What type of system do you need to read and surf the Internet? Buying a system to read e-mail and surf the Internet will not cost you as much money as a system gamers need, which require high end video cards, hard drives and extra RAM.

How Should I Connect A Monitor To My Desktop Computer?

You will need to attach your video card to the port on the motherboard. The motherboard ports located on the IO panel are sufficient if your computer doesn't have a dedicated videocard. The most common connections are HDMI, DisplayPort, DVI and VGA. One cable will be sufficient to link each monitor and the computer at once.

Why Do I Need To Buy A New Computer?

There are many reasons to need a desktop computer. If you find you are begging time on friends systems, or have work you’d like to do at home instead of staying late at the office, these might be good reasons to get your own system. It will also allow you more quality time at home instead of working late, visiting friends, or the library to access a computer.

What Is An All-in-one Desktop Computer?

Unlike a tower PC, which requires an external monitor, an all-in-one PC comes with its own monitor. Of course, you can still connect additional monitors if you want to maximize your workstation.

How Do I Install Software On A Desktop That Doesn't Come With A Installed DVD Drive?

If you don't have a DVD drive on your desktop computer, you can commonly find the software to download and install from the manufacturer's websites. You can also get an external DVD drive and connect it by USB to install software from disks.
