ASUS has introduced two new Intel 200-series chipset-based ROG STRIX motherboards in Mini-ITX form factor, the H270I and B250I. As an H and B series boards, both H270I and B250I didn’t support any kind of OC, and memory speeds are also limited to the stock Intel 2400 MHz up to two sticks of memory total of 32 GB.
Both motherboards feature a single PCIe 3.0 x16 slot and two M.2 ports, one in the front over the PCH heatsink and one at the back of the motherboard. The top M.2 SSD will be cooled by the double-decker PCH heatsink. The back M.2 port support full 3.0 x4 speeds as well as Intel Optane Memory, but only one of them supports SATA-based M.2 solid state drives.
Other connectivity includes 4x SATA 6Gb/s ports and support Intel Rapid Storage Technology, although only the Strix H270I has RAID 0, 1, 5, 10 and Intel SRT capabilities. The H270I supports 8x USB 3.0 ports (6x rear, one header for 2x front ports) and the B250I supports 6x USB 3.0 ports (4x rear, one header for 2x front ports) and two USB 2.0 ports (two rear). The H270-based model also has 2x gigabit LAN ports (1x Intel I219V and 1x Realtek RTL8111H), while the B250-based model only has 1x gigabit LAN port powered by Intel’s I219V controller.
Both motherboards come with dual-band 802.11ac Wi-Fi with MU-MIMO, Bluetooth 4.1, and a 2×2 external antenna. Display outputs come in at 1x HDMI 1.4 and 1x DisplayPort 1.2. For audio both features ROG SupremeFX eight-channel HD audio solution, based on the Realtek ALC1220A codec. There are three fan headers with one of them supports a water pump or a high amperage fan with fully customizable with ASUS’ Fan Xpert 4 UEFI/software fan controls.
