- Great Mobo - Salmaan, 9 January 2026
Needed a Quick and affordable Motherboard as my friends motherboard died out. And It works great. Only downside is that it has 2 ram slots instead of 4 , so there is some bottlenecking but Not noticeable at all. So its defs good for an emergency build or perfect for an itx build.
- Can't beat MSI! - Wihan, 9 June 2025
A solid budget motherboard with great features and performance. Good power delivery, sturdy build, and plenty of USB ports. A great value for its price.
- Solid replacement board - Rod, 2 July 2024
Had an MSI A320 board that died after 4 years and this was recommended as a drop in replacement - so far so good, it’s working now with my old 3200G and 2x8GB Ripsaws @3200MHz - but interestingly Windows 11 seemed to crash regularly until I uninstalled the MSI software bundle SW (all of it...not sure which one was the culprit)
I appreciate the quick service and good advice from the team, thank you!
