2U GPU server barebone for AI and HPC workloads

This ASUS ESC4000A-E12-26WGP is a 2U rackmount barebone designed for AI, ML and HPC tasks. It accommodates a single AMD EPYC 9004 series processor and up to four dual-slot GPUs. The chassis targets builders who need dense GPU compute in a standard rack form factor.

Single Socket SP5 processor

The board provides one Socket SP5 for 4th Generation AMD EPYC 9004 CPUs up to 400W TDP. Twelve 288-pin DDR5 slots support 4800 or 4400 MHz RDIMM and 3DS modules across 12 channels for a maximum of 3TB. Buyers who require dual-socket scaling cannot use this platform.

Independent CPU and GPU airflow tunnels with 2600W

Separate airflow tunnels isolate CPU and GPU thermals for air or liquid cooling. Two 2600W 80 Plus Titanium redundant supplies deliver uninterrupted power. No installed CPU, memory or storage means thermal and acoustic behaviour depends entirely on the components selected.

Highlights

  • Supports up to 3 TB DDR5 memory across 12 channels
  • Four dual-slot GPUs fit in eight PCIe 5.0 slots
  • Redundant 2600 W 80 Plus Titanium power supplies
  • Liquid or enhanced air cooling for up to 400 W CPU
  • Six front bays for NVMe, SATA and SAS drives

Questions about this item

What does the 400 W CPU rating mean once the processor is installed in this server?

The single SP5 socket accepts one AMD EPYC 9004 series processor with a maximum TDP of 400 W, and the cooling design provides independent airflow tunnels for that thermal envelope.

How does the PCIe 5.0 interface cap GPU bandwidth in this chassis?

Eight rear slots run at Gen5 x8 electrical for single-slot GPUs, while two additional slots provide Gen5 x16 links for dual-slot cards or other expansion.

What physical space and mounting does this 2U barebone require?

It fits a standard 2U rackmount bay, supports up to four dual-slot GPUs, and includes front bays for two 2.5-inch and four 3.5-inch drives.
