Description

AM5 and X870 for a powerful Ryzen

The board has an AMD AM5 socket and the X870 chipset. ASUS AI Overclocking profiles the processor and cooling and suggests a suitable overclock, while Dynamic OC Switcher automatically swaps between a manual overclock and Precision Boost Overdrive based on current and temperature thresholds. Overclocking Load Guard protects the system from sudden current spikes so experiments do not end in a crash.

Two USB4 ports on the rear panel

The rear panel has two USB4 ports for fast external SSDs and USB4 devices. On top of that there are five USB 3.2 Gen 2 Type-A ports, one USB 3.2 Gen 2 Type-C and four USB 3.2 Gen 1 ports, so there is room for a keyboard, mouse, headset and more. For the front panel there is a USB 3.2 Gen 2x2 header, two USB 3.2 Gen 1 headers and two USB 2.0 headers.

Up to 192 GB of DDR5 and four M.2 slots

Four DIMM slots take up to 192 GB of dual-channel DDR5 memory, and unbuffered memory is supported with and without ECC. Six drives can be installed in total: four M.2 SSDs and two SATA III devices, with support for RAID 0, 1, 5 and 10. The graphics card gets a PCIe 5.0 x16 slot, alongside two more x16-size slots running PCIe 4.0. At 305 × 244 mm the board follows the ATX standard, so it fits ATX cases.

Wi-Fi 7, Bluetooth 5.4 and 2.5G networking

Wireless connectivity is Wi-Fi 7 (802.11be), joined by Bluetooth 5.4. For wired networking there is a 2.5 Gbps Ethernet port, up to 2.5 times faster than standard gigabit. ASUS AI Networking II optimises network traffic so games and video calls are not held back by large downloads. The HDMI and DisplayPort outputs on the rear panel serve processors with integrated graphics.

Cooling and audio sorted in one click

ASUS AI Cooling II balances temperatures and noise with a single click, so the PC is neither loud nor hot. There are five headers for case fans. Audio comes from a Realtek ALC4080 with 7.1 channels, and the board offers an optical S/PDIF output, a microphone input and a headphone output. A Clear CMOS button resets the BIOS to defaults, and SATA cables are included.

Who this motherboard is for

Gamers and enthusiasts building a powerful AM5 PC who want AI tools to make overclocking easier; creators who rely on fast USB4 external drives and need plenty of USB ports; and anyone who needs Wi-Fi 7, four M.2 SSDs, up to 192 GB of memory and room for several expansion cards.
