ASUS RS700A-E12-RS12U-16W1G 1U Dual-Socket AMD EPYC 9004 Rackmount Server
Overview
The ASUS RS700A-E12-RS12U-16W1G is a 1U rackmount server built around dual AMD EPYC 9004 series (Genoa) processors, targeting dense compute workloads where rack space is at a premium. With support for two Socket SP5 (LGA 6096) CPUs, 24 DDR5 DIMM slots across 12 memory channels per CPU, and 12 x 2.5-inch hot-swap bays supporting NVMe, SATA, or SAS drives simultaneously, the RS700A-E12-RS12U-16W1G fits data center deployments requiring high core density without sacrificing storage flexibility. The 1+1 redundant 2600W/1600W 80 PLUS Titanium hot-swap power supply keeps efficiency losses minimal at sustained load — Titanium-rated PSUs hit ≥96% efficiency at 50% load, which translates to measurable power savings in 24/7 environments. Three PCIe expansion slots plus one internal PIKE slot accommodate GPU, NIC, or HBA add-in cards without pulling the server offline for reconfiguration. ASUS Control Center (Classic) provides centralized management for fleets of these units. Windows Server 2019 is a validated OS configuration per ASUS compatibility documentation.
Compatibility
Processor socket SP5 (LGA 6096) supports AMD EPYC 9004 series (Genoa) CPUs — confirm specific EPYC SKU against ASUS's CPU compatibility list before ordering, as not every Genoa variant is validated for this board. Memory is DDR5, 24 slots total (12 per CPU, 1 DIMM per channel); DDR4 is not supported on SP5 platforms. Storage backplane accepts up to 12 x 2.5-inch drives in any mix of NVMe, SATA, or SAS — SAS requires a compatible HBA/PIKE controller seated in the internal PIKE slot. The PIKE slot is separate from the three external PCIe expansion slots, so SAS connectivity does not consume a primary expansion slot. Validated operating systems include Windows Server 2019; Linux distribution support follows ASUS's OS compatibility matrix.
Installation Notes
This is a 1U chassis — verify rack clearance and airflow planning before deployment, as 1U designs run higher internal temperatures under peak dual-CPU load and require unobstructed front-to-rear airflow. Hot-swap drive bays and the redundant PSU both allow field replacement without powering down, reducing planned maintenance windows. The 2600W peak power draw requires appropriately rated PDU circuits; confirm per-circuit amperage against your facility's power distribution before racking.
