Maximize your productivity with the ASUS Pro WS B850M-ACE SE AM5 mATX Motherboard as the foundation for your next computer build. Designed for compact workstations, this highly configurable mATX motherboard packs high-speed connectivity with support for AMD Ryzen 7000 / 8000 / 9000 and EPYC 4005 series processors to power demanding AI workloads.
Four DDR5 slots allow you to install up to 256GB of 8000 MT/s memory for smooth multitasking. For storage, there are four SATA III and two M.2 PCIe 5.0 slots that let you quickly load applications and large project files. Alternate configurations allow you to turn off the second M.2 slot to enable the high-bandwidth MCIO connector. Similarly, you can switch from the default SATA mode to U.2 drive support. You can install a powerful graphics card into the PCIe 5.0 x16 slot and a compatible expansion into the PCIe 4.0 x16 (x8 mode) slot.
The rear panel includes two 10 Gb/s compatible USB-C 3.2 Gen 2 ports, one of which supports DisplayPort video output, alongside three USB-A ports. You can use the two USB-A 2.0 for peripherals such as a mouse and keyboard. An internal header enables a front-facing 20 Gb/s USB-C port. One 10 Gb/s Ethernet port and a 2.5G port provide fast connectivity to compatible network devices. A dedicated 1 Gb/s Ethernet port is available for BMC and IPMI management. You can use the DisplayPort, HDMI, and VGA outputs with an integrated graphics CPU. Windows 10 or 11 is required to take advantage of all the motherboard's features.
