GIGABYTE R123-C00-AA01 barebone server 1U AM5 4-bay SATA 400W

SKU CH-95D1-083T3 MPN R123-C00-AA01

A 1U rack server barebone with four SATA hot-swap bays, AM5 socket for AMD EPYC 4004 or Ryzen 7000 CPUs, four DDR5 ECC UDIMM slots, one PCIe Gen5 x16 slot and a 400W 80 PLUS Gold supply

  • 1U form factor fits dense racks
  • AM5 socket supports EPYC 4004/4005 and Ryzen 7000/9000 CPUs

  • Dual-channel DDR5 with ECC on four DIMM slots
  • Single 400W 80 PLUS Gold power supply included

1U AM5 barebone for single-socket builds

The R123-C00-AA01 is a 1U rackmount barebone that accepts one AM5 processor from the Ryzen 7000 or EPYC 4004 series. It targets small-business IT, hosted services and edge workloads that need server-grade management in a compact chassis. No CPU or memory is installed, so integrators choose the exact configuration.

Four hot-swap SATA bays plus M.2 Gen4

Four front 3.5-inch or 2.5-inch SATA bays provide hot-swap storage with RAID 0, 1 or 10 support. A single M-key M.2 slot adds PCIe Gen4 x4 capacity for 2242 or 2280 cards. Dual-channel DDR5 fills four 288-pin slots up to 32 GB per DIMM with ECC or non-ECC unbuffered modules.

Replaces older 1U SATA platforms when density

The board adds a PCIe Gen5 x16 full-height slot and two low-profile Gen4 x4 slots for networking or acceleration cards. Dual 1 GbE LAN and Aspeed AST2600 graphics handle remote management. The 400 W 80 PLUS Gold supply limits CPU TDP to 105 W, so high-core-count parts beyond that envelope need a larger power option.

Questions about this item

Will the AM5 socket accept my existing Ryzen 7000 processor and DDR5 memory?

The AM5 socket supports Ryzen 7000 series CPUs up to 105W TDP and four 288-pin DDR5 DIMM slots running dual-channel with ECC or non-ECC unbuffered modules up to 32GB each.

How can I verify the 400W 80 PLUS Gold power supply is delivering stable power after installation?

Use the Aspeed AST2600 BMC interface or GIGABYTE Management Console to monitor real-time voltage rails, fan speeds and power draw reported by the onboard sensors.

Which drive trays and riser cards ship with the 1U chassis and what must I source separately?

The box includes four 3.5/2.5-inch SATA hot-swap trays, riser CRC1014 with one full-height PCIe Gen5 x16 slot and riser CRC1021 with two low-profile PCIe Gen4 x4 slots; CPU, memory and storage drives are not included.
