Description
The ASUS PRIME B850M-K motherboard, in black and with a micro ATX form factor, is designed around AMD's AM5 socket. It supports AMD Ryzen 7000 Series, AMD Ryzen 8000 Series and AMD Ryzen 9000 Series processors, so you can build a current configuration on a foundation with room to grow. In the memory department it supports DDR5-SDRAM in two DIMM slots, with a maximum capacity of 128 GB and dual channel operation, as well as being compatible with buffered and unbuffered modules and with ECC and non-ECC memory. For storage it offers M.2 and SATA III interfaces, with support for HDD and SSD drives, up to six compatible drives and four HDDs, and allows RAID configurations at levels 0, 1, 5 and 10. With these credentials, the ASUS PRIME B850M-K fits into compact systems that need disk speed and room for memory expansion without giving up the micro ATX format.
