The motherboard or mainboard is the component that connects all the different parts of your computer. Often it has some integrated components like a sound card, enabling your computer to play sound, or a network card, to connect your computer to the network. The standard form factor (size) for motherboards is ATX, you need at least a midi-tower to fit one of those in. Micro-ATX motherboards are often more complete and have more onboard devices, like a video board and fit in smaller cases, but are generally less expandable.

Great item and great performance
This is my second ASUS motherboard. I have always found ASUS motherboards good for over clocking and lots of tweaking options. Wifi 6 is great and Wifi signal is more stable. The audio quality is good too.
Every feature you could want. Great motherboard all round
Pros: Everything is where it is supposed to be.Cons: A BIOS flashback button would have been useful in updating a very out of date BIOS.
Great board great service, arrived very fast at a great price
