1U dual-EPYC barebone

The ASUS RS700A-E12-RS4U-16W10G is a 1U rackmount barebone designed for dual AMD EPYC 9004 Series processors up to 400 W each. It targets datacentre operators building general-purpose or AI-ready nodes who will supply their own CPUs, memory and storage.

EVAC cooling and 1+1 power

Enhanced volume air cooling handles the 400 W per socket thermal envelope in a 1U chassis. A 1600 W 1+1 redundant 80 Plus power supply delivers continuous operation during a single-module failure.

24 DDR5 slots and tri-mode bays

Twenty-four 288-pin slots accept DDR5 4800/4400 RDIMM or 3DS RDIMM across twelve channels per socket. Four front bays support NVMe, SATA or SAS drives, while two internal M.2 sockets add boot or cache flexibility. Three PCIe 5.0 slots plus an OCP 3.0 slot provide high-bandwidth expansion for GPUs or networking.

Questions about this item

How do I install the AMD EPYC 9004 processors into the Socket SP5 sockets, and what step is often missed?

Align the processor triangle with the socket marker, lower the carrier frame evenly, then torque the captive screws in the labelled sequence; the step most often missed is applying the included thermal interface material before seating the heatsink.

Which components will need replacement first during the server's service life?

The 1600 W redundant 1+1 power supply fans and the EVAC heatsink fans are the primary moving parts rated for continuous 400 W TDP cooling; plan to inspect them at regular intervals and replace if bearing noise or airflow drops.

What thermal limit appears first when both CPUs run sustained 400 W workloads?

The EVAC heatsink design is validated for up to 400 W per socket; if inlet air temperature rises or fan speed cannot increase further, the processor will hit its thermal throttle point before the 1600 W power supplies reach their output ceiling.
