ASUS today introduced the Prime B350M-E, an entry-level socket AM4 motherboard in the micro-ATX form-factor, based on the AMD B350 chipset. Built in the narrow micro-ATX form-factor, this board draws power from a combination of 24-pin ATX and 8-pin EPS power connectors, conditioning it for the AM4 SoC with a simple 6-phase VRM. The SoC is wired to two DDR4 DIMM slots, supporting up to 32 GB of dual-channel DDR4 memory. Expansion slots include one reinforced PCI-Express 3.0 x16 slot, and two PCI-Express x1 slots.

Storage connectivity on the Prime B350M-E includes one 32 Gb/s M.2 slot with NVMe booting support, and four SATA 6 Gb/s ports. USB connectivity includes two 10 Gb/s USB 3.1 ports (both type-A), and six 5 Gb/s USB 3.0 ports (four on the rear panel, two by headers). Display outputs include one each of DVI, D-Sub, and HDMI. Gigabit Ethernet and 6-channel HD audio make for the rest of it. The board features red LEDs, and RGB headers that let you plug in third-part RGB LED lighting, and control it using the ASUS Aura Sync software. The company didn't reveal pricing.
