AM5 platform with 16+2+1 phase power

The board uses AMD X870 silicon and an AM5 socket to support Ryzen 9000, 8000 and 7000 series processors. A 16+2+1 phase VRM with 80A Dr.MOS delivers stable current for multi-core workloads. Four DDR5 slots accept up to 256GB at 8000 MT/s with EXPO and XMP profiles. ECC un-buffered memory is supported for error correction.

Wi-Fi 7, 2.5Gb LAN and dual USB4 40Gbps

Onboard Wi-Fi 7 and Bluetooth 5.4 provide modern wireless throughput. A Realtek 2.5Gb Ethernet controller handles wired traffic. Two USB4 Type-C ports reach 40Gbps for fast external storage or displays. Additional USB 3.2 Gen2 Type-A ports and HDMI round out the rear I/O. Four M.2 sockets support PCIe 5.0 x4, 4.0 x4 and 4.0 x2 alongside two SATA 6Gb/s ports with RAID 0/1.

White ATX board for high-end Ryzen builds

The white ATX aesthetic suits showcase systems that want coordinated colour schemes. PCIe 5.0 x16 and Gen5 M.2 readiness match current flagship GPUs and SSDs. DIY conveniences include BIOS Flashback, tool-free M.2 installation and an integrated I/O shield. Builders needing more than two SATA ports or legacy PCIe 3.0 expansion should consider alternative chipsets.

Questions about this item

Will the 16+2+1 phase 80A Dr.MOS VRM need any fan maintenance over time?

The VRM uses passive heatsinks; dust buildup on the fins is the only upkeep, so occasional compressed-air cleaning keeps temperatures stable.

What limits sustained PCIe 5.0 x4 M.2 throughput during long writes?

The M.2 slots share the chipset’s PCIe 5.0 x4 lanes, so thermal throttling on the drive itself becomes the first bottleneck under continuous heavy load.

How much heat and noise does the board add when the 2.5GbE, Wi-Fi 7 and Bluetooth 5.4 radios run all day?

The network controllers are low-power and passively cooled; they add negligible heat and no audible noise during 24/7 operation.
