ASUS PRIME B650M-K AM5 DDR5 Micro-ATX Motherboard
Stepping up from A620, the ASUS PRIME B650M-K is a Micro-ATX DDR5 board on the AMD B650 chipset for AM5, giving Ryzen gaming builds a PCIe 5.0 M.2 slot, faster wired networking and a BIOS FlashBack button for CPU-less BIOS updates.
Key Specifications
- Socket AM5 for AMD Ryzen 9000, 8000 and 7000 Series desktop processors, supporting CPUs up to 170W
- AMD B650 chipset with 2 DDR5 DIMM slots, up to 96GB, and DDR5 speeds up to 8000+MHz overclocked, with AMD EXPO support and OptiMem II trace routing
- 1 PCIe 4.0 x16 slot plus 2 PCIe 4.0 x1 slots
- 2 M.2 slots and 4 SATA 6Gb/s ports, with the first M.2 slot supporting PCIe 5.0 x4 mode for Ryzen 9000 and 7000 Series processors and the second supporting PCIe 4.0 x4 mode

- BIOS FlashBack button, VRM heatsink, M.2 heatsink and PCH heatsink with hybrid fan headers and Fan Xpert 2+
- 1 Aura RGB header and 2 Addressable Gen 2 headers for Aura Sync lighting
BIOS FlashBack and OptiMem II Memory Routing
BIOS FlashBack lets the BIOS be updated using only the button and a USB drive, which removes the need for an older supported processor when preparing the board for a newer Ryzen chip, while OptiMem II routing helps preserve signal integrity for higher DDR5 speeds.
- Install a Ryzen 9000, 8000 or 7000 Series processor up to the 170W limit.
- Fit two DDR5 modules for dual-channel memory up to 96GB.
- Place the fastest NVMe SSD in the PCIe 5.0 M.2 slot and a second drive in the PCIe 4.0 M.2 slot.
- Use the PCIe 4.0 x16 slot for a graphics card and connect high-speed wired networking through the 2.5Gb Ethernet port.
