The ASRock AB350M Pro4 is a motherboard in the micro ATX format and has graphics cards with a fast PCI Express 3.0 slot with full x16 connection. There is also one PCIe 2.0-x16 (4 lanes) and x1 slots for other expansion cards. Up to 64 GB of DDR4 memory take up the four RAM banks, with corresponding memory running at 2.666 megahertz. The internal connection repertoire includes a USB 3.0 header and two USB 2.0 headers for 2 and 4 ports, respectively.
Special features at a glance:
1x PCIe 3.0 x16 for high-end gaming graphics cards
6x USB 3.0 Type A & Type C + 1x Turbo M.2 Slot PCIe 3.0 x4
3x PWM fan ports (4-pin)
DDR4 memory up to 2.666 MHz
Modern UEFI BIOS including temperature monitoring
Such as SSDs and hard disks, the board is managed by four SATA 6G connectors (including RAID support), as well as a horizontal M.2 slot, which is connected to four PCI Express 3.0 lanes, enabling enormous speeds up to To 32 Gbit / s. M.2 SSDs of 42 to 80 mm in length can be used, and the advanced NVM Express protocol, which has been specially optimized for highly parallelized data carrier accesses of modern PCIe SSDs, is supported. A further M.2 port with SATA-6G interface is additionally provided.
A small highlight on the ASRock AB350M Pro4 is also that a I / O panel on the back of the motherboard is a USB 3.0 port with a type C socket. The new USB type C port is especially thin and can be inserted at both ends. USB 3.0 or USB 3.1 Gen 1 achieves maximum speeds of 5 Gbit / s per port.
Finally, three fans with a 4-pin PWM connector and a RGB LED strip can be connected directly to the board via a 4-pin connector. On the motherboard, additional devices and components can be connected to the ASRock AB350M Pro4 via USB 3.0 and 2.0, Gigabit LAN, universal PS / 2 or three audio sockets onboard sound via the I / O shield. In addition, there are three monitor outputs (HDMI, VGA and DVI-D) for the image display via an integrated APU graphics unit (optional).
