More expensive motherboards usually mean better quality components. Cheap capacitors are a common failure point on inexpensive motherboards. … In the case of our two example motherboards you can immediately tell there’s a difference. The MSI board only has two RAM slots and a single full-length PCIe slot.

What is RGB?

RGB stands for Red, Green and Blue. These are the three primary colours of the additive colour system. In lighting we encounter RGB for coloured lighting. RGB lighting enables you to create millions of different colours of light, all based on these three primary colours.

Additive versus subtractive colour system

The additive colour system is based on the mixing of different light colours. When two primary colours are mixed, you get a lighter colour. Mix the three primary colours (red, green and blue) and you will get white light. Unlike with paint, yellow is not a primary colour.

The best example of the additive colour system can be found in computer screens and televisions. Use a strong magnifying glass and you’ll notice that every pixel consists of a red, green and blue sub-pixel. By playing with the brightness of these sub-pixels, you can create any light colour.

The image below shows the mixing scheme of the additive colour system. It looks like this:

  • Red + green = yellow
  • Red + blue = magenta
  • Blue + green = cyan
  • Red + blue + green = white

The additive colour system is not to be confused with the subtractive colour system, which is used e.g. for print. This system is called ‘subtractive’ because less and less light is reflected when mixing colours, mixing results in darker colours. The primary colours of the subtractive colour system are cyan, magenta and yellow.

RGB lighting

RGB lighting can form all colours, ranging from warm orange to cool blue. It is often used in LED strips. In RGB LED strips we distinguish three types:

  • Classic RGB: a LED strip with triple diodes (red, green and blue on one diode). To form white light, the three diodes are used simultaneously. With these classic RGB the white light may contain traces of other colours. This white light will not have the same brightness as the white light of a true white LED.
  • RGB+W: A LED strip with triple diodes (red, green and blue on one diode) and a separate white diode for pure white light. Because of the larger distance between the two diodes of the same colour, evenly distributed light is not guaranteed. With this type of RGB, the distinction between the different light beams will be easier to see.
  • RGBW: A LED strip with quadruple diodes (red, green, blue and white on one diode). Provides nice evenly distributed lighting in any colour.

What To Consider When Buying A Motherboard for Desktop PC 

The motherboard is arguably a PC’s most important component, nothing else works without it and it decides what upgrades you can make to your desktop PC in the future. Here is what you need to consider before you buy.

Form Factor

Initially you’ll need to select a form factor. ATX motherboards are common, as is micro ATX (although these are smaller in size and reduce the number of expansions slots). When you’re buying a new motherboard and not sure what size will fit, you can always measure your old motherboard and compare it with different sizes. The ATX board is popular, as it has the addition of more expansion slots, which can be useful.

Processor Socket

After choosing a form factor you’ll need to choose a processor socket.  There has been different types of sockets used in the past however three are only applicable today. These are LGA, PGA and BGA. Intel uses LGA, whilst AMD use PGA. BGA sockets aren’t as popular as the latter because these are permanently bonded to the motherboard so they cannot be serviced or upgraded.  Depending what type of socket you have on your motherboard, it will determine what processor you can buy.  So this you will probably need to consider what CPU you want first, then buy your motherboard.

RAM (Random Access Memory)

Next up, RAM, short for Random Access Memory. Fundamentally the motherboard you buy will determine the amount and type of RAM you can have. Therefore it’s worth being mindful of this before making a decision buying a motherboard. Consequently, we would recommend choosing a motherboard that can accommodate at least 16 GB, even though if you don’t plan to buy that much initially, you have the option to use this memory later. In addition, look for a board that offers 4 or more memory slots. This means you can install 2 RAM modules to begin and you will have spare room for memory upgrades in future.

PCI Slots

A PCI slot is a connection or port that is located on the motherboard. They have been the standard type of expansions slot for years and they allow expansion cards to be connected. Depending on how you plan to use your computer, you’ll need to consider if your motherboard has the slots to suit your requirements. If you’re a gamer, you’ll want to have at least one full speed PCI express x16 slot and you’ll need multiple of those, if you want to connect multiple cards. Motherboards also offer standard PCI slots and smaller PCI express slots for other cards, like sound cards, Wi-Fi adaptors and other connectivity expansions.


If you buy a motherboard with features already built in, you don’t have to worry about buying additional expansion cards. A more common feature which is usual included on the majority of motherboards is on-board audio.  However this is usually only suitable for mid-range speakers. It is worth noting that better motherboards often bundle Wi-Fi and Bluetooth features as well, but you’ll have to spend more cash for these features. Nevertheless they will reduce the need for expansion cards.


When considering buying a motherboard you may to need consider the number of SATA ports you’ll need. Each SATA port allows you to connect an optical drive and storage drives, like a SSD or HDD. So it’s important to make sure your motherboard has all the SATA ports you need for all of your drives. It is also worth noting that you need to make sure your motherboard offers the SATA 6 gigabytes standard, which is also known as SATA 3.0.  Furthermore, you might need to consider peripheral connections, for example a USB 3.0.
