You must know what you are doing

  • Beautiful design
  • Easy to connect
  • Clear manual
  • BIOS is an old version

Everything in the manual is explained in clear steps, so that the motherboard could be quickly connected and installed.
After turning on the system, there was no image. After a long search it turned out to be a known problem and a flash of the BIOS is required. The correct version is quickly found on the MSI site. Would that be why the flash button was placed on the back instead of on the motherboard?
After setting up the latest version everything runs like a train and I am very satisfied with the product

Solid with handy software and drivers available

  • 2.5G Ethernet
  • RGB hardware switchable
  • Looks nice
  • 90 Degree SATA Cable

Nice motherboard from MSI that is very good in the market in terms of price-quality.
I'm not a big fan of RGB states myself. You can easily disable it with this motherboard via a hardware switch.

Drivers and dashboard application are easy to get and also do its thing. Flashing BIOS was a breeze.
BIOS itself is also quite advanced (overclocking, XMP profiles, ...).

The only drawback I have experienced for myself is that 1 of the 2 SATA cables has a 90 degree connection. Not a problem in itself, but with the case I use (Fractal Design C) you can place up to 3 HDDs behind the mobo (backplate). So you need straight SATA cables for this.

Very satisfied with my purchase.
