Our take on the ASRock Rack B850M-C Micro ATX Motherboard
The ASRock Rack B850M-C is a micro ATX board for AMD Socket AM5 that leans toward workstation and server-style use rather than gaming flair. It pairs a 12+2+1 Dr.MOS power stage with four DDR5 slots rated to 8000+ MHz with EXPO/XMP, a PCIe 5.0 x16 slot, three more x16-length slots, three M.2 mounts and four SATA ports. Networking is Realtek Gigabit LAN plus WiFi 6 and Bluetooth, with HDMI for integrated graphics. Against consumer B850 micro ATX boards it trades RGB and premium audio for slot count and stability, and its ALC897 audio and single 1GbE port are modest next to rivals with 2.5GbE and better codecs. It suits builders who need many expansion cards and drives in a compact chassis more than gamers chasing fast networking and onboard audio.

Questions and answers
- Does it support Ryzen 9000, 8000 and 7000 chips?
- Yes. It uses AMD Socket AM5 and is listed for Ryzen 9000, 8000 and 7000 series processors, so current and recent AM5 CPUs fit.
- How many M.2 and SATA drives can I connect?
- Three M.2 drives: one PCIe Gen5x4, one Gen4x4, and one Gen3x2 with SATA3. There are also four SATA3 ports for 2.5-inch or 3.5-inch drives.
- Is the networking fast enough for a workstation?
- It has Realtek Gigabit LAN plus WiFi 6 and Bluetooth. That is fine for most office and lab work, but it is 1GbE, not 2.5GbE, so large network transfers are capped there.
- Can I run it without a graphics card?
- Yes, if your Ryzen chip has integrated graphics. The board has an HDMI output for that, which suits headless or low-power builds.
- Does it support memory overclocking?
- Yes. It supports XMP and EXPO profiles and is rated for DDR5 speeds up to 8000+ MHz in overclocking mode across four DIMM slots.
- What is included for updating the BIOS?
- A BIOS Flashback button lets you update firmware without booting, and the ASRock Auto Driver Installer handles driver setup. A Post Status Checker helps diagnose boot problems.
