ASUS Prime X670E-PRO AM5 ATX Motherboard: what it is and who it suits

The ASUS Prime X670E-PRO is an ATX motherboard for AMD's AM5 socket, with the X670 chipset and DDR5 memory support. The listing is short, giving the name, socket, chipset, memory type and size, so this page explains what those terms mean for a PC build.

What the listing tells us

The product is described as the X670E-PRO, an AMD X670, Socket AM5, ATX, DDR5-SDRAM motherboard, with the manufacturer part number 90MB1BL0-M0EAY0. It measures 12.0 x 9.6 x 2.0 inches and weighs 3.7 lb (about 1.7 kg). Beyond that, details such as ports, M.2 slot counts and power design are not in the listing, so check ASUS's specification sheet for them.

What AM5 means

AM5 is the socket on AMD's current desktop platform. It is a land-grid design: the contact pins are in the motherboard socket, not on the processor. AM5 boards use DDR5 memory only, so DDR4 modules from an older PC will not fit. Which processors the board supports, and whether a BIOS update is needed first, is listed on ASUS's support pages.

What the X670 chipset does

The chipset is the board's traffic controller. It decides how many extra connections the board can offer beyond those from the processor, such as additional USB ports, SATA ports and PCIe lanes. The "E" in X670E is typically used for boards that offer PCIe 5.0 for the graphics slot and for M.2 storage; it stands for "extreme" in AMD's naming. Check the exact slots on the specification sheet to see where PCIe 5.0 is provided.

DDR5 memory

DDR5 offers higher speeds and bandwidth than DDR4, and the modules have a different notch so they can't be mixed up. Memory is sold in kits, and many people choose two or four modules. The supported speeds and capacity are listed by ASUS for the model.

ATX size

ATX is the standard full-size motherboard format, so most mid-tower and full-tower cases take it. Smaller cases may only accept Micro-ATX or Mini-ITX, and a board this size won't fit those. The Prime line from ASUS is a general-purpose range of boards.

Who it suits

It suits someone building or upgrading a desktop PC on the AM5 platform who wants an ATX board with an X670E chipset and DDR5 memory. It is a platform change: moving from an older AMD or Intel system means a new processor, memory and often a different cooler mount.

What to check before you buy

• Processor support: confirm your exact Ryzen model is on ASUS's list and check BIOS requirements.
• Memory: DDR5 only; check ASUS's list of tested memory kits.
• Case: check that your case takes ATX boards and has room for your graphics card.
• Slots and ports: the listing doesn't give the number of M.2 slots, USB ports or video outputs, so read the full specification.
• Wireless: the listing doesn't mention Wi-Fi or Bluetooth, so confirm whether the board has them or whether you need an adapter.
• Cooler and power supply: check the cooler is AM5-compatible and the power supply has the connectors listed in the manual.
• What's in the box: check cables, brackets and the manual.
