SKU CH-KYP4-CHA2N

ATX motherboard with AM4 socket for Ryzen 2nd and 3rd Gen CPUs, includes I/O shield only

  • CPU Socket TypeAM4
  • CPU TypeRyzen Series
  • Form FactorATX
  • ASUS PRIME B550-PLUS AC AMD motherboard
  • Supports AMD Ryzen 2nd and 3rd Gen CPUs out of the box
  • ATX form factor fits standard desktop cases
  • AM4 socket ready for Ryzen series processors
  • I/O shield included in the box

Socket AM4 compatibility

This ATX motherboard accepts AMD Ryzen second- and third-generation processors without a BIOS update. First-generation Ryzen CPUs are not supported even after an update. Fifth-generation Ryzen chips require a BIOS flash using a compatible second- or third-generation processor installed first.

Power delivery and thermal design

The board uses a standard ATX power layout for the B550 chipset and draws typical desktop power under normal loads. No active chipset fan is present so noise remains low during everyday operation. Thermal performance scales with the installed CPU cooler and case airflow.

CPU generation support matrix

Buyers who need first-generation Ryzen support cannot use this board. Builders planning a fifth-generation Ryzen upgrade must already own a supported second- or third-generation CPU to perform the required BIOS update. The package includes only the motherboard and I/O shield.

商品問答

How do I install the ASUS PRIME B550-PLUS AC motherboard and what step is often missed?

Mount the board using standard ATX standoffs, fit the included I/O shield before securing the motherboard, then connect power and data cables; the step often missed is installing the I/O shield first.

What maintenance or replacement will the ASUS PRIME B550-PLUS AC need later?

The board is sold as motherboard and I/O shield only, so you may need to source SATA cables, a Wi-Fi antenna, and a driver disk separately for future upgrades or repairs.

What limit appears first on the ASUS PRIME B550-PLUS AC under sustained use?

The VRM cooling capacity will throttle high-core-count Ryzen 9 3900X or 3950X CPUs before other limits are reached.
