MSI has now released the B350I PRO AC, a mini-ITX option for those looking to build a small form factor system featuring AMD’s Ryzen processors or a 7th generation Raven Ridge APUs. Deviating from their more recent AM4 offerings primarily marketed towards gamers, the B350I PRO AC has been designed to cater for all users including professionals and has a number of new features commonly seen on the bigger high-end boards.
The MSI B350I PRO AC sports a formidable 9 phase power delivery design (6+2+1), using 'high efficiency' drivers and chokes - normally we would see this configuration on higher-end motherboards that would be promoted users looking to do a little bit of overclocking, so it is clear that MSI is going for stability here. Due to the size, a single PCIe 3.0 x16 slot features MSI’s Steel Armor to reinforce against damage from heavy graphics cards that might apply some torque to the slot.
This Mini-ITX B350 has support for dual channel DDR4 memory with speeds of up to DDR4-3200 and with two memory slots being present, the B350I PRO AC can be installed with modules with a total maximum capacity of 32GB. The B350I PRO AC offers multiple storage solutions including four SATA 6Gb/s ports and a single M.2 slot that supports a PCIe 3.0 x4 or SATA drive. This board does support RAID 0, 1 and 10 arrays via the SATA 6Gb/s ports.
On the rear panel, the MSI B350I PRO AC has two USB 3.1 Gen 2 Type-A ports thanks to the inclusion of the ASMedia ASM3142 controller. Also included is a further two USB 3.1 Gen 1 ports, two USB 2.0 ports and a single PS/2 combo port for keyboards and mice. Audio wise, this model features a Realtek ALC887 codec with three 3.5mm audio jack inputs included on the rear panel. The single Gigabit LAN port is driven by the more budget Realtek 8111H Gigabit LAN controller and also included is an Intel dual band 3168 Wi-Fi module which has support for Wi-Fi 802.11ac, (2.4/5GHz), and this also includes Bluetooth 4.2 connectivity. Lastly, for users of AMD's Raven Ridge APUs, MSI has implanted a DisplayPort 1.2 and HDMI 1.4 port to make the most out of the onboard graphics.

mITX with a powerful APU (I currently use the i7-5775C), M.2 SSD and a picoPSU, all in a box of 200x200x50mm (2 liter). Powerful enough to play games like Borderlands 1+2, WoW, etc, draws less than 150W and is dead silent.Reflex - Sunday, January 7, 2018 - link
https://dan-cases.com/dana4.phpThere are some really good options for mITX and full graphics cards.

Please learn to count power phases properly. It's right, there in front of you - yet you get it completely wrong.meacupla - Sunday, January 7, 2018 - link
how many power phases does it really have?Is it 6 doubled (3 practical) , or really 6?
Is it 2 doubled (1 practical), or really 2?
What does that last 1 phase power?

So with RR, that pcie slot would be 8 lanes, right?I wonder what folks will use it for, since they dont need a gpu?
Good news with RR, is a single water cooling block cools both processors. With good cooling, it could be quite an overclocker.

Actually ASRock just leaked some updated mini-ITX board for the new X470 chipset. The ASRock Fatal1ty X470 Gaming-ITX/ac with support for Ryzen 2000 series CPU/APU's. Hopefully it will take advantage of the added PCIe 3.0 lanes with a second NVMe port.So I don't get why this MSI board gets all the attention. There are already better boards from ASRock and Gigabyte available. The ASRock Fatal1ty B350 Gaming-ITX/ac beats this board in features and specs.

I will not buy motherboards with USB 2.0 on it, no sense in that, wasted connection, they know USB 3.0 is backward compatible with USB 2.0.dromoxen - Saturday, April 21, 2018 - link
Not all the time .. try installing widows and you soon find that it doesn't always see your usb3 ports till after it has been installed (so your usb k+m wont work) so you cant install widowsmlhm5 - Saturday, February 17, 2018 - link
Built a Rylan e-h60, Ryzen 5 2400g, 16gb 3200, 250 Samsung 960 M.2, hdplex 160, and HP 230W power brick. Very small. I love it.
