AM5 DDR5 platform for Ryzen 7000 8000 9000

This ATX motherboard uses the AMD B650 chipset and an AM5 socket. It accepts Ryzen 7000 8000 and 9000 series processors. Four 288 pin slots support up to 192 GB of dual channel DDR5 memory with AMD EXPO profiles.

Sustained load thermal design

A 12 plus 2 plus 1 Duet Rail power system with dual 8 pin CPU connectors feeds the CPU. Extended heatsinks and 7 W per mK MOSFET pads dissipate heat during long sessions. M.2 Shield Frozr covers both CPU linked Gen 4.0 x4 slots.

PCIe 4.0 x4 M.2 from CPU

The primary M.2 socket connects directly to the processor and runs at PCIe 4.0 x4. It accepts 22110 and 2280 drives. A second CPU linked M.2 slot takes 2280 and 2260 devices. Both deliver full bandwidth without chipset sharing.

Highlights

  • Supports Ryzen 7000, 8000 and 9000 series CPUs on AM5 socket
  • DDR5 memory up to 6000+ MHz OC with AMD EXPO on four 288-pin slots
  • 12+2+1 Duet Rail power with dual 8-pin CPU connectors for stable delivery

Questions about this item

How loud or hot does the 12+2+1 Duet Rail Power System get when the board runs all day?

The 12+2+1 Duet Rail Power System uses dual 8-pin CPU power connectors with MOSFET thermal pads rated for 7W/mK, extended heatsinks and M.2 Shield Frozr to keep temperatures controlled during continuous operation.

Which DDR5 memory kit must I already own to populate the 4x288pin slots?

You need un-buffered non-ECC DDR5 modules; the board supports AMD EXPO profiles up to 6000+ MHz (OC) and JEDEC speeds from 4800 to 5800 MHz, with a maximum capacity of 192 GB across four slots.

Will my SATA 6Gb/s drives and PCIe 3.0 x1 cards still work on this AM5 platform?

Yes — four SATA 6Gb/s ports and one PCIe 3.0 x1 slot from the chipset are provided, so existing SATA SSDs or HDDs and legacy x1 expansion cards remain compatible.
