While it is not as impressive as it would be if this were a mini-ITX Threadripper board, building a motherboard that is over 50% socket may be asking a bit too much. Instead the B350I PRO AC is designed for Socket AM4 Ryzen chips.
The board is designed with 9-phase PWM design (6+2+1), which will ensure great stability along with an electrically isolated Realtek ALC887 codec and Steel Armour protecting that lone PCIe 16x slot. Memory of up to 32GB of DDR4-3200+ is supported, important to get the most out of your Ryzen processor. There are two USB 3.1 Gen2 ports on the back as well as HDMI out, so you could use this as an unobtrusive VR box with the right GPU installed; WiFi and Bluetooth connectivity will also come in hand for that.
Check out the full specifications here, while we await availability.
