AMD EPYC 9005 1U server barebone
The ASUS RS501A-E12-RS4U-16TW is a single-processor 1U server barebone built around AMD EPYC 9005 processors with up to 192 Zen 5c cores. It targets organisations that need dense compute for AI and HPC workloads in a rack-mount form factor. The platform supports 12-channel DDR5 memory running at up to 5200MHz across 24 DIMM slots. Processor TDP support reaches 450 watts.
Check CPU cooler clearance and power budget
Verify that your rack provides enough airflow for the enhanced-volume air-cooling heatsink designed for high-TDP processors. Confirm that your power distribution can deliver the wattage required by a 450-watt CPU plus any add-in cards. Ensure the chassis depth fits your rack rails and that cable routing allows access to the front drive bays. The board includes an OCP 3.0 slot and three PCIe 5.0 slots for expansion.
EVAC heatsink and front NVMe access
The enhanced-volume air-cooling heatsink handles processors with higher TDP without liquid cooling. Four 2.5-inch NVMe drive bays on the front panel allow hot-swap storage changes without opening the chassis. Two single-slot GPUs can be installed for accelerated workloads. ASMB11-iKVM with ASPEED AST2600 provides remote management over a dedicated interface.

Questions about this item
Does the barebone include the AMD EPYC 9005 processor, DDR5 DIMMs, NVMe drives or GPU cards, or must they be purchased separately?
The unit is a barebone chassis with motherboard, power and cooling installed; the EPYC 9005 CPU, up to 24 DDR5 DIMMs, up to four 2.5 NVMe drives and up to two single-slot GPUs are all purchased separately.
Which EPYC 9005 processor variant should I choose for this 1U server?
Select any single-socket EPYC 9005 CPU with a TDP of 450 watts or lower; the EVAC heatsink and 12-channel DDR5 5200 architecture support the full 192 Zen 5c core range within that thermal envelope.
What does the three PCIe 5.0 slots figure mean once the server is built?
It provides three full-width PCIe 5.0 expansion lanes for add-in cards such as OCP 3.0 networking, additional storage controllers or the two supported single-slot GPUs.
