Here are 5 Newbie Mistakes You Should Avoid! 

1) Buying Parts Without Proper Consideration Of The Workload

First and foremost, building a PC is not cheap. That is why you should always take into consideration what you would be using the PC for so that you can allocate your budget where it's most needed and save yourself from spending way too much.
Many tend to buy parts unknowingly or resort to buying cheap parts and then get frustrated because it can't run PUBG or Adobe Premiere Pro. Most likely it is because the build is not capable of running these applications. Types of Workload includes:
  • Web Browsing, Office Work(documents, spreadsheets etc), light tasks
  • Gaming and Live Streaming
  • Production (Photo and Video Editing, 3D Rendering, AutoCAD, etc)

2) Not Researching Enough About Compatibility Of Parts 

You probably know the basics. Processor, Memory, HDD, Motherboard, Graphics Card, Power Supply, Monitor, Keyboard and Mouse. But with the vast selection of brands and models of each component, you also have to double or triple check the compatibility of these parts so that you won't waste any time in finding the necessary parts and also avoiding spending more because you have the compatibility wrong.
Some Quick Tips:
  • Intel and AMD Ryzen processors require different types of motherboards(ex. Intel 7th/8th Gen processors require LGA1151 socket like the Z370 motherboards, while the Ryzen series of AMD requires AM4 socket like the B350 or A320)
  • DDR3 and DDR4 memory sticks are DIFFERENT from each other and cannot be intermixed. You also have to check your motherboard and processor for compatibility with this
  • GPUs have different sizes which you may need to check first with your motherboard of choice for compatibility

3) Buying 2nd Hand Parts Without Guidance(especially for first time buyers)

This is almost the same with #2 but this time it's when buying 2nd hand parts online. Buying 2nd hand parts is a good way to save some cash on parts that you need for your PC Build BUT without proper knowledge on what to ask the sellers or how to check for red flags, you may lose not only your time but also your hard earned money.
Some Quick Tips:
  • Always ask for more photos. Many sellers only provide a small amount of photos and sometimes even hide defects from the units you might be buying. It also helps if you ask for a photo that is taken while you are in negotiations with them. 
  • Ask their reason for selling. GPU Cards, for example, have jacked up in prices due to the decrease in supply caused by the Bitcoin Mining craze. Because of this, you might find sellers that used the GPUs in Mining and selling them in very cheap prices, don't fall into this trap as most likely it is an already stressed unit from all the mining it did.
  • Always ask for receipt and if the part you're buying is still on warranty. This is for your personal peace of mind and of course having warranty is always a good thing
  • If you're buying from OLX or FB Groups/Marketplace, make sure to check their ratings(if on OLX) or ask for people to vouch for the seller. Make sure to also agree on a MEETUP instead of having items shipped to avoid getting scammed.
  • Having a friend who has experience on buying 2nd hand parts would greatly help you finding great parts for great deals!

4) Not Reading The Manuals or Watching/Reading How-To Videos on PC Assembly

Yes. I'm a big advocate of ACTUALLY reading the manuals. For newbies that are just starting out to build your rigs, it's best to actually read the manuals of parts that have it. Not only does it guide you step by step, you also learn alot in handling PC parts which may help you when Upgrading or building a new one in the future.
Also helps if you watch a few videos on how to install certain parts especially if it's complicated parts such as watercooling systems and such.

5) Forgetting To Buy Software(Operating System, Applications, etc) and Forgetting It Costs Money Too

After knowing some stuff about the hardware, you have a list of parts that you're already targeting, went to the store to buy these parts, went home and assembled it and then forgot that you need an Operating System to boot this up and applications to do whatever you want to do with your newly built PC.
Okay, to be honest, I've had my fair share of use of Cracked Applications and even the bootleg version of Operating Systems.

BUT ever since I started working, I've been purchasing a few legit applications when I can afford it because of a lot of reasons..


  • You get software Updates on purchased applications. Which means a few things, upgraded features, security patches, bug fixes and more
  • You don't have to worry about your data being leaked, your computer to be hacked or spied on, virus attacks here and there etc. (Mainly caused by cracked applications)
  • You get premium support on some software applications


  • It costs money. If you've only considered the price of your hardware and didn't add software costs you will be bankrupt in no time (just kidding, but it will hurt your bank accounts)


Building a PC is not as easy as putting parts together. There are a lot of things to be considered especially if you are on a tight budget and don't have much room for error. 
Hopefully these 5 Newbie Mistakes will help you take a step back and plan much better on building your own PC.
It really pays to do your research and I guess by reading this article you are already one step ahead :P
