MSI B450I Gaming Plus Ac WiFi DDR4 AMD Motherboard

The MSI B450I Gaming Plus AC WiFi is a Mini-ITX form factor motherboard designed for AMD Socket AM4, measuring just 17.0 cm x 17.0 cm (6.7 in. x 6.7 in.). It is built around the AMD B450 chipset and supports AMD Ryzen 1st and 2nd Generation processors, as well as Ryzen with Radeon Vega Graphics and Athlon with Radeon Vega Graphics APUs on the AM4 socket — making it a capable platform for compact gaming and productivity builds. Memory support extends to two DDR4 DIMM slots accommodating up to 32 GB in dual-channel configuration. JEDEC speeds of 1866, 2133, 2400, and 2667 MHz are supported natively, while MSI's A-XMP overclocking mode pushes compatibility up to DDR4-3466. Both non-ECC UDIMM and ECC UDIMM memory (running in non-ECC mode) are accepted. Storage options include one M.2 Key-M slot supporting PCIe 3.0 x4 (with Ryzen 1st/2nd Gen) or PCIe 3.0 x2 (with Athlon Vega APUs) and SATA 6 Gb/s in 2280 size, plus four SATA 6 Gb/s ports from the chipset. RAID 0, RAID 1, and RAID 10 configurations are available for SATA devices. A single PCIe 3.0 x16 slot handles discrete graphics at full x16 bandwidth with Ryzen 1st/2nd Gen CPUs. Wireless connectivity is handled by a pre-installed Intel Dual Band Wireless-AC 3168 module (seated in the M.2 Key-E slot), delivering 802.11ac 1x1 dual-band (2.4 GHz / 5 GHz) speeds up to 433 Mbps alongside Bluetooth 4.2. Wired networking uses a Realtek 8111H Gigabit LAN controller. Audio is provided by a Realtek ALC887 codec delivering 7.1-channel High Definition Audio output. The rear I/O panel includes a PS/2 combo port, DisplayPort, HDMI 1.4, two USB 3.1 Gen1 Type-A (from the CPU), two additional USB 3.1 Gen1 Type-A (from the chipset), two USB 2.0 Type-A, Gigabit LAN, Wi-Fi/Bluetooth antenna connectors, and HD audio jacks. Onboard display outputs are active only with Vega Graphics-equipped processors; the DisplayPort supports up to 4096×2304 at 60 Hz and the HDMI 1.4 port up to 4096×2160 at 30 Hz. Internal headers include a 24-pin ATX and 8-pin ATX 12V power connectors, one USB 3.1 Gen1 internal connector (for two additional ports), one USB 2.0 internal connector (for two additional ports), a 4-pin CPU fan header, a 4-pin system fan header, front panel audio, system panel connectors, chassis intrusion connector, Clear CMOS jumper, and two 5050 12 V RGB LED strip headers. EZ Debug LED provides straightforward hardware troubleshooting at a glance.
