ASUS PRIME B850M-K & Ryzen 7 9700X Combo

This ASUS motherboard and CPU bundle pairs the PRIME B850M-K board with an AMD Ryzen 7 9700X processor. The board uses the AM5 socket and the B850 chipset in a micro-ATX layout. It is sold as a matched kit for builders who want a coordinated platform foundation.

Suits AM5 builders wanting DDR5 and PCIe 5.0 ready

The combo fits users moving to the AM5 platform who need 8 cores and 16 threads for gaming or productivity. The 40 MB cache and 5.5 GHz max boost clock support high frame rates. Builders needing integrated graphics or a different core count should evaluate other AM5 processors.

8400 MT/s DDR5 overclock ceiling

The motherboard supports memory overclocks up to 8400 MT/s, which sets the practical speed limit for installed DDR5 kits. Buyers should confirm their chosen memory modules are validated for this frequency on the board's QVL. The CPU officially supports DDR5 5600 without overclocking.
