ASUS PRIME B840-PLUS WIFI ATX Motherboard

Onboard graphics output is available when a compatible CPU is installed. The board suits a standard desktop build with modern connectivity.

Who this suits and who should look elsewhere

It suits builders assembling a PC around a Socket AM5 CPU who want integrated Wi-Fi 6E, 2.5 Gigabit LAN and USB-C 3.2 Gen 1 on an ATX form factor. It is not for buyers who need more than one USB-C 3.2 Gen 1 port or who require additional high-speed USB standards not listed here.
