Description

AM5 socket and B840 chipset for modern Ryzen builds

Socket AM5 is AMD's current desktop platform, and the B840 chipset gives you a straightforward base for building around it. Choosing AM5 now means you're working with today's processors and the DDR5 memory standard instead of buying into an older platform, which makes this board a sensible starting point for a fresh gaming or work PC.

Four DDR5 slots for room to grow

With four DDR5 memory slots, you can start with two modules and add more later as your needs grow. DDR5 is the memory type AM5 systems are built for, so you're set up for current RAM kits. It's a flexible layout for gamers, streamers and anyone who runs lots of applications side by side.

Dual M.2 slots and built-in Wi-Fi

Two M.2 slots let you fit a fast system drive plus a second drive for games or projects without messy cabling. Built-in Wi-Fi means you can get online wherever your desk happens to be, with no separate wireless card taking up an expansion slot. A wired RJ45 port is also there when you want a cable connection.

Who it suits

This board suits anyone building a new AMD Ryzen PC on the AM5 platform: gamers putting together a mid-range rig, home users upgrading from an older system, and creators who need plenty of memory and fast storage. It's also handy for setups where running an Ethernet cable isn't practical.
