Socket AM5 X870E platform

This ATX motherboard targets AMD Ryzen 9000, 8000 and 7000 series processors on the AM5 socket. It is built for enthusiasts who need strong power delivery and extensive high-speed storage options in a full-size board.

18+2+2 digital twin power phase

The 18+2+2 phase digital twin design with premium chokes and capacitors on an 8-layer PCB delivers steady power for high-core-count CPUs. This specification determines whether the board can sustain heavy all-core workloads without throttling.

Builders wanting five M.2 slots

Suits DIY builders who need five M.2 sockets supporting PCIe 5.0 and 4.0, USB4 Type-C, WIFI 7 and Bluetooth 5.4 in one package. Users requiring more than two SATA ports or legacy PCI slots should consider alternative boards.

Questions about this item

What does the 18+2+2 power phase design mean for a Ryzen 9000 series CPU in daily use?

The 18+2+2 digital twin power phases deliver stable current to the CPU socket, helping maintain boost clocks on Ryzen 9000 series processors under sustained loads.

How does the PCIe 5.0 x16 slot limit graphics card bandwidth compared to the PCIe 4.0 x16 slot?

The single PCIe 5.0 x16 slot provides up to twice the theoretical bandwidth of the PCIe 4.0 x16 slot for compatible GPUs.

What clearance does the ATX form factor and integrated I/O shield need in a standard case?

The board follows the ATX layout with an integrated I/O shield, so it fits any case that supports standard ATX motherboards.
