I'm very pleased with the quality of this product, it's very good and it's very easy to use. I'm very pleased with the quality of the product and it's very easy to use, it's very easy to use and it's very easy to use. The motherboard was just not suitable for my processor (ryzen 5 5600g) but after a bios update everything works great! I recommend it.
Wonderful card from MSI. The seriousness and the quality of the Mortar series is not to be proven anymore.
It's really well made, and everything is there.
No coldwine and other quirks, and no fan (vs AMD X570 chipset)
The PCI 4.0 port does its job well.
The slots (SATA ports, fan ports, etc.) are well thought out and well designed.
And as far as connectivity on the back panel is concerned, everything is there.
Great!
