## Description

Review: Good fast board - Great entry board also ddr4 rgb 5v plus 2x12v led strip lights for under desk behind monitors. Hdmi,vga and dvi sockets. Easy ro install as it comes with a disk. But remember to take of encryption on ssd in your old bios menu. Highly recommend if you don't want to go through the new ddr5 setup.
Review: Nice general purpose motherboard - My PC, used to control electronic equipment, failed and I needed to get something working fast. I decided to swap the motherboard, retaining memory, processor and disks. After some research, this Asus seemed to be a good solution and I have not been disappointed. It's a good, versatile workhorse with a flexible BIOS - not a flashy games platform. The build process went smoothly and it was up and running in a couple of hours. There's a lot of scope for tuning and I'm still experimenting to find a decent combination of performance and reliability.

### ⭐⭐⭐⭐ Decent motherboard but not perfect.
*by M***L on 29 August 2025*

Great motherboard for the price, my only issue was that other motherboards from Asus with a lower price point have heat sinks for the M.2 hard drives, having to find a suitable 3rd party one is a nuisance. This needs addressing.
