1U server barebone for AMD Ryzen 7000/9000

This 1U barebone accepts a single AM5 processor up to 105 W TDP and provides four DDR5 DIMM slots with ECC support. It is built for general-purpose workloads that need dual 10 GbE networking and a PCIe 4.0 x16 expansion slot. Buyers who require more than one CPU socket or larger drive bays should look elsewhere.

Dual 450 W 80+ Platinum redundant power supplies

The unit ships with a 1+1 redundant PSU configuration rated at 450 W each and 80+ Platinum efficiency. This design keeps power delivery stable and allows one supply to fail without downtime. No fan noise or thermal data is supplied by the manufacturer.

Four DDR5 slots supporting up to 48 GB per DIMM

Memory capacity tops out at 48 GB per module, with speeds of 5200 MT/s at one DIMM per channel and 3600 MT/s at two DIMMs per channel. ECC and non-ECC UDIMMs are both supported. This ceiling decides whether the platform fits your memory footprint.

Questions about this item

How is the CPU installed in the AM5 socket, and what step is often missed?

Lift the retention lever, align the processor triangle with the socket marker, place it gently without force, lower the frame, then secure the lever; the step often missed is confirming the lever clicks fully into the locked position before mounting the cooler.

What maintenance will the dual 450W redundant power supplies need over time?

Dust the intake mesh every few months, verify both units show green LEDs, and plan to replace a failed module by sliding the release latch and inserting a matching 450W 80+ Platinum unit while the server stays running.

What thermal limit appears first when the Ryzen 7000 or EPYC 4004 series CPU runs at 105W TDP continuously in this 1U chassis?

The CPU will hit its 105W TDP ceiling and throttle before the dual 450W redundant supplies or the 1U airflow path become the bottleneck.
