TechPowerUp came across a bunch of photos and specifications of the ASUS ROG STRIX B350-I Gaming. This new Mini-ITX motherboard hasn't been announced yet but it's already listed online by a Swedish e-tailer.
In essence, this is a slimmed-down version of the ROG STRIX B350-F GAMING. It features the AMD B350 chipset and is intended for Socket AM4 Ryzen processors, it supports up to 32GB DDR4-3200 (OC) and features a single PCI Express x16 slot. Overall, it has a nice set of features:
However, belying the board's small size, the B350-I-Gaming features a wealth of connectivity options, including two external USB 3.1 Generation 2 ports as well as four USB 3.1 Generation 1 ports. Additionally, one USB 3.1 Generation 1 header, and even a USB 2.0 header are available internally. Four SATA 6.0 Gbit/s headers, along with two M.2 slots round out the connectivity options, all of which is great for a board this size. Gigabit ethernet as well as built-in wifi, and SupremeFX 8-Channel High Definition Audio are also featured.
