Rack server GIGABYTE R123-X00-AA01 1U — single-socket Intel Xeon Scalable platform, LGA 1700, DDR5, 4 DIMM, 2.5 inch bays x4, 400 W PSU (80 PLUS Gold)

GIGABYTE R123-X00-AA01 is a 1U rack server based on a single-socket Intel Xeon Scalable platform with an LGA 1700 socket. The chassis supports one processor and four DDR5 DIMM slots (up to 128 GB, RDIMM supported at 4000 MT/s). Storage options include four 2.5" drive bays (HDD/SSD, SATA) and one M.2 slot. Expansion includes one PCIe x16 (Gen5) and two PCIe x4 (Gen4) slots. Networking is provided by an Intel I210-AT Gigabit controller with two RJ-45 LAN ports and a dedicated management LAN. The server includes TPM 2.0, VGA and COM ports, four USB 3.2 Gen1 Type-A ports, and a 400 W 80 PLUS Gold power supply. The unit measures 430 × 43.5 × 536 mm and is designed for compact rack deployments.

Advantages

The server offers a compact 1U rack form factor with support for modern LGA 1700 processors and DDR5 memory, enabling higher memory bandwidth in a small footprint. Redundant-seeking features such as TPM 2.0 and an 80 PLUS Gold certified 400 W PSU contribute to platform security and energy efficiency. A mix of PCIe Gen5 and Gen4 expansion slots and multiple 2.5" bays support flexible storage and add-on card configurations for diverse workloads.

How to use

Install the server into a standard 19" rack following rack-mount instructions and secure with appropriate rails or mounting hardware. Populate the single-socket LGA 1700 CPU socket with a compatible processor and install DDR5 DIMMs across the four slots according to the motherboard memory population guidelines. Connect storage devices to the 2.5" bays or the M.2 slot and attach network cables to the Gigabit RJ-45 ports; connect the management LAN if out-of-band management is required. Power the unit from a stable AC source and configure BIOS/firmware settings, including TPM, network, and boot order, before installing the operating system and server software.

Recommendations

For reliable operation, deploy the server in a controlled rack environment with adequate front-to-back airflow and ambient temperature between 10–35 °C. Use RDIMM modules that match supported speeds for optimal performance, enable TPM 2.0 in firmware for enhanced platform security, and consider the 80 PLUS Gold 400 W PSU rating when planning power and redundancy for rack-level deployments.
