1U rackmount barebone for AMD AM5 CPUs

The ASRock Rack 1U4LW-B650/2L2T RPSU is a 1U server barebone built around the AMD B650 chipset and a single AM5 socket. It supports AMD Ryzen 7000 series and EPYC 4004/4005 processors with a thermal design power up to 170W. Four hot-swap 3.5-inch SATA drive bays and a redundant 450W power supply suit general-purpose workloads in a standard rack.

Quad-channel DDR5 with ECC up to 198 GB

Four 288-pin UDIMM slots accept DDR5 ECC or non-ECC memory running at 5200 MHz with one DIMM per channel or 3600 MHz with two per channel. Maximum capacity reaches 198 GB using 48 GB modules. No memory is installed, so builders must populate the slots with validated DDR5 modules from the qualified vendor list.

Redundant 450W power supply in 1U

The 1+1 redundant 450W power supply unit delivers continued operation if one module fails. Dual 10GbE ports via Broadcom BCM57416 and dual 1GbE ports via Intel i210 handle network traffic. A full-height PCIe 4.0 x16 slot and one M.2 slot with PCIe 5.0 x4 connectivity provide expansion for storage or accelerator cards.

Questions about this item

How does the 170 W CPU power limit affect which AMD Ryzen 7000 series processors I can run in this 1U barebone?

The board supports Ryzen 7000 series CPUs up to a 170 W TDP, so models such as the 7950X, 7950X3D, 7900X and 7900X3D are within spec, while higher-wattage parts would exceed the thermal design.

What practical throughput can I expect from the dual 10 GbE ports provided by the Broadcom BCM57416 controller?

The BCM57416 delivers two RJ45 ports at 10 GbE line rate, giving up to 10 Gbit/s per port for storage replication, backup or high-speed LAN traffic.

Will a full-height PCIe 4.0 x16 add-in card fit in the 1U chassis without a riser?

The system includes the RB1UX16_G4 riser, which provides one full-height PCIe 4.0 x16 slot, so a standard FH card installs directly in the 1U enclosure.
