The ASUS PRIME B850M-K, model 90MB1LV0-M0EAY0, is a micro ATX motherboard built around the AMD B850 chipset and Socket AM5 platform. It supports AMD Ryzen 7000, 8000 and 9000 Series processors, with provision for one CPU. Designed to provide a capable foundation for a modern AMD system, it combines DDR5 memory support, PCIe expansion, M.2 and SATA storage connectivity, integrated networking, eight-channel HD Audio and a broad selection of external and internal interfaces. Onboard display connectivity is also provided for use with a processor that supports graphics output.
Memory support is based on a dual-channel DDR5 architecture with two 288-pin DIMM slots and a maximum supported capacity of 256 GB. Supported memory clocks include 4000 MHz as well as 4100 MHz and 4200 MHz when overclocked. The board supports on-die ECC, non-ECC and ECC memory integrity options, together with AMD EXPO technology. ASUS Enhanced Memory Profile technology is included, with both AEMP and AEMP III among the motherboard's hardware features, while ASUS OptiMem II is incorporated as part of the memory implementation.
Storage options cover both M.2 and conventional SATA drives. Two M.2 sockets are provided, including one 2280 M.2 slot and one M.2 Key M socket supporting 2242, 2260 and 2280 form factors. The storage interfaces comprise one PCIe 5.0 M.2 connection and one PCIe 4.0 M.2 connection, alongside four SATA-600 connectors using 7-pin Serial ATA connections. AMD RAID Xpert2 Technology is supported for RAID functionality and storage management. An M.2 heatsink, M.2 Q-Latch, M.2 screw package and M.2 backplate rubber package are also part of the supplied feature and accessory set.
Expansion capabilities include a PCIe 5.0 x16 slot and a PCIe 4.0 x16 slot operating in x4 mode, allowing the motherboard to accommodate graphics and other compatible expansion hardware. ASUS SafeSlot and Q-Slot features are included, while Q-DIMM, Q-Connector, Q-Code and Q-LED form part of the wider ASUS Q-Design feature set intended to support system assembly, configuration and hardware management.
The PRIME B850M-K provides extensive USB connectivity through both its rear interfaces and internal headers. External connections include two USB 3.2 Gen 2 ports, two USB 3.2 Gen 1 ports and four USB 2.0 ports. Internally, the motherboard provides a USB-C 3.2 Gen 1 header, two USB 3.2 Gen 1 connections through headers and four USB 2.0 connections through headers. Additional internal connections include serial, SPDIF output, SPI and audio headers, giving the board a varied set of options for compatible chassis connections and system hardware.
Display connectivity consists of one HDMI interface and one DisplayPort, with graphics output requiring a suitable CPU with onboard graphics capability. A combined PS/2 keyboard and mouse connection is also available. For wired networking, the motherboard incorporates a 2.5 Gigabit Ethernet interface, while ASUS LANGuard is included among its hardware features. Preboot eXecution Environment, or PXE, support and wake on LAN functionality are also provided, along with wake on PME support.
Audio is handled by an eight-channel HD Audio implementation compliant with the High Definition Audio standard. Rear audio connectivity comprises dedicated mini-jack connections for line output, microphone input and line input. The audio feature set also includes jack detection, jack retasking and an anti-pop function, while an internal audio header and an SPDIF output header provide further connection options.
Power delivery uses a 24-pin main motherboard power connector together with an 8-pin ATX12V connection. The board incorporates an 8+2+1 phase power design and ASUS DIGI+ VRM technology, complemented by a VRM heatsink design. A dedicated Water Pump Header is also included for compatible cooling configurations.
Firmware management is based on an AMI UEFI BIOS and includes ASUS EZ Flash for BIOS updating. BIOS FlashBack functionality is supported through a dedicated BIOS FlashBack button and BIOS FlashBack LED, while CrashFree BIOS 3 provides another ASUS firmware-related feature. The motherboard also includes ASUS EZ DIY functionality, a DIY Friendly Design and a CPU socket lever protector, bringing together several features intended to assist with system building and firmware management.
Protection and durability features include ASUS 5X Protection III, ESD Guards and overvoltage protection. ASUS Stainless Steel Back I/O and ASUS SafeSlot are also incorporated into the hardware design. Together with the motherboard's power, cooling and firmware features, these technologies form part of the PRIME B850M-K's focus on stable system operation and protection of critical hardware.
The motherboard additionally supports BMC remote management and is compatible with Windows 11. Included software comprises Armoury Crate, ASUS Fan Xpert 4, ASUS CPU-Z and ASUS Control Center Express. Adobe Creative Cloud is supplied as a free trial, Norton 360 Deluxe is included as a 60-day trial, and WinRAR is also provided.
Measuring 24.4 cm wide and 22.1 cm deep, the PRIME B850M-K uses the micro ATX form factor.
