Our take on the Asus Prime B860M-A WIFI-CSM LGA-1851 DDR5 mATX Desktop Motherboard

The Asus Prime B860M-A WiFi-CSM is a micro-ATX board for Intel's LGA-1851 Core Ultra Series 2 chips. It pairs a 7+1+1+1 power stage with DDR5 support across four slots, PCIe 5.0 x16 for the graphics card, two M.2 slots and USB-C at 20Gbps. WiFi 6E and 2.5Gb Ethernet are built in, so no add-in card is needed. It suits a compact mid-range build where connectivity matters more than overclocking; the Prime line is Asus's value tier, so it gives up the heavier VRMs and extra M.2 slots of the TUF and ROG boards above it.
