DIY computer- Part I

Thinking that you’d like to build your own computer? Then this post is for you. Here is the Slice Shared  by Ebby Samson!

Questions to ask your self before building your computer…

Is it for work or is it for the family to share?

Are you going to use it for gaming?

If you are going to use it for the whole family, desktops are a better option as they can hold more data and perform faster.

Desktops, if they run out of storage space, have additional slots for extra hard drives.If they get slower, have slots for adding more RAM, unlike laptops. Laptops are very limited when it comes to upgrading.

If you are going for Gaming  and  you have a limited budget, a wise option is to build your own computer. This is coming from my  experience of building my very own computer.

 Apart from feeling awesome about myself, the other benefits of building my own computer,

  • Easy to upgrade
  • Much faster computer because of hand picked  components

Let’s get into business and get our hands dirty. The basic components we need are a motherboard, processor, RAM, storage, and the externals: PC case, power supply, monitor and the peripherals (keyboard, mouse, speakers). But you’d probably need more if you will be gaming a lot. CPU For gaming, you need a good CPU from Intel Core I5 or I7 series. You also need a lot of RAM, maybe around 4GB. The best will be 8GB – it also has the best value to performance ratio most average to hardcore users need.


Graphics cards

You also need a separate graphics card for playing 3D games because most brands only provide the integrated graphics which is inbuilt in the motherboard. Many graphics cards are in the market, but sources show that Nvidia has a few more features than most others.


 If you need more RAM(>4 GB) you need a 64-bit operating system. But for most budget computers, 32 bit systems are good enough. From my point of view, the best OS is, of course, none other than Windows.

The components like  case, power supply unit(PSU)and optical drive, it is best to buy the cheapest  ones. If you need to use lots of DVDs and CDs, get an optical drive that matches your needs. Take note that, you need a PSU that can supply at least 460 Watts as your computer should not be under powered.

The link between the important components and not so important components should be understood clearly.

The motherboard should be compatible with your components. Check the CPU socket type (LGA775, LGA1155, AM2, FM2+)  and the Type of RAM (DDR2, DDR3).

 I recommend buying DDR3 type RAM and LGA1150 socket type CPU as DDR3 is faster than DDR2 and LGA1150 supports the latest 4th generation Intel Core I5 and I7 processors which is vital for a good experience. 1

The top CPU brands in the market today are Intel and AMD. So, which one is better or suits you?

If you want good performance and can pay for it, Intel is the best choice.

If your target programs and applications can use multiple cores, AMD is a cheaper alternative as it has a better speed when all the cores are being used.

What I have learned is, the Intel Core i7 4790 which has four cores and goes up to 4 GHz but, the AMD FX 8350 has 8 cores and goes up to 4.2 GHz. The Intel has a much better performance of one core. At the same time, the AMD has an equally  good performance with all 8 cores and is cheaper than the Intel. Also, AMD has the ability to run most games.

DIY Computer

Graphics cards (GPUs) generate the graphics in your computer. The two best graphics card producers today are Nvidia and AMD. They are about the same but, AMD is louder and heats up faster. Nvidia cards are cooler and run games faster than the AMD. The reason is,  AMD is made for mining and is a little less committed to running games. So basically, Nvidia is cheaper, quiet, cool and is better for games. AMD is a little more expensive, heats up faster, is noisier but is better at mining. Don’t forget to make sure your motherboard  has a PCIe slot for the GPU (or more if you are having more than one GPU). It is best to buy a motherboard with at least four slots for the RAM  as in the future, you will definitely  need to upgrade your computer.

For my computer DIY Computer I got an Intel Core i7 4790k CPU, it is the best available and it can go up to 4.4 GHz. I chose a MSI Z87-G43 gaming motherboard as I wanted a powerful computer. It has four DDR3 RAM slots, LGA 1150 CPU socket but only one PCIe slot as my budget didn’t allow more than one GPU.




DIY Computer Part IIMy GPU was a GTX 760 ti with 2GB graphics RAM. I got one piece of RAM from Kingston which was 8GB which left me with three RAM slots for future upgrades. My hard drive was 1TB. I got a case from Cooler Master, a 460Watt PSU with an average Optical Drive. All this was within my budget.

Have you tried to build your own computer? If so, can you share your experience here?

    I think you should go for the gtx 970 strix, although expensive, it gives a lot better performance for price.

      I would have gone for that but it was too far outside my budget

    Also, based on what you said for the power supply, you should spend a bit more on it, going semi/fully modular, so that it would be a lot easier to when you get to wiring, which can be a pain sometimes, especially for newbiew.
