MSI has released the first Mini-ITX motherboard in its lineup based on the Intel H810 chipset ? the PRO H810I WIFI model. Despite belonging to the budget segment and its compact size, the board supports PCIe 5.0 and a Wi-Fi 7 module.
In the latest BIOS firmware for motherboards based on the B650 chipset, GIGABYTE suddenly disabled PCIe 5.0 support in the main PCIe x16 slot. Although this option was never officially announced, it did exist and was used by many.
The Colorful CVN B850I GAMING FROZEN motherboard has been announced. It is a 10-layer, Mini-ITX (17 x 17 cm) motherboard based on the B850 chipset and AM5 socket with support for the most advanced AMD processors.
