About this item

ASUS RS500A-E11-RS12U Datasheet

The ASUS RS500A-E11-RS12U is a 1U rackmount single-socket server built for general-purpose and enterprise applications. Powered by a single AMD EPYC 7742 processor and supporting up to twelve front hot-swap 2.5-inch drives, it delivers high core density and PCIe Gen4 expansion for demanding data center applications.

  • Single AMD EPYC 7742 — 64-Core (64 Total), 7nm
  • 3x PCIe Gen4 Slots — 1x x16 full-height half-length, 1x x16 low-profile, and 1x x8 low-profile, plus 1x OCP 3.0 mezzanine socket (Gen4 x16 link); installed add-in card occupies one slot, so available expansion depends on configuration
  • 16x DDR4 DIMM Slots — 8-channel DDR4, RDIMM/LRDIMM/LRDIMM 3DS up to 256GB per module at speeds up to 3200 MHz
  • 12× 2.5" Hot-Swap Bays — backplane supports 12x NVMe/SATA/SAS devices, front-accessible, plus 2x onboard M.2 sockets; SAS drives require an add-in controller
  • Dual 1GbE Networking — Intel I350-AM2 controller, dedicated management port, plus 1x Mellanox ConnectX-5 add-in controller
  • No RAID Controller — none installed; platform supports SATA and NVMe drives directly
  • Dual 800W Platinum-Rated PSUs — 1+1 redundant; requires C13 power cords, not included
  • Aspeed AST2600 Remote Management — out-of-band monitoring and control via ASMB10-iKVM
  • CPU Only — no RAM or drives included. Ships with inner rails only (outer rails not included) and all 12 drive carriers

The ConnectX-5 version of the ASUS RS500A-E11-RS12U combines a dual-port Mellanox ConnectX-5 network adapter with a single AMD EPYC 7742 processor, 64-Core (64 Total). This refurbished 1U server has sixteen DDR4 DIMM slots and twelve 2.5-inch hot-swap storage bays. Expansion includes three PCIe Gen4 slots (one x16 full-height, one x16 low-profile, and one x8 low-profile) plus an OCP 3.0 mezzanine socket; the installed add-in card occupies one of these, so available expansion capacity depends on the current configuration.

This animation is a visual aid only and does not represent the actual testing methodology, sequence, or results for this drive.

We test every server before you do.

Every server Server Part Deals sells passes an internal 4-stage testing protocol before it ships. While many resellers stop at a basic power-on check, we validate installed hardware, firmware, system performance, thermals, and stability under sustained load. Each server is tested to confirm that it meets or exceeds its listed specifications.

Stage 1: Physical Inspection

  • Chassis and structural inspection
  • Port, connector, and backplane check
  • Fan, heatsink, and airflow inspection
  • Shipping-damage and component-security check

Stage 2: Hardware & Firmware Validation

  • CPU, RAM, and storage verification
  • BIOS and firmware validation
  • RAID and controller detection
  • Remote-management interface check

Stage 3: Performance Testing

  • Processor and memory benchmarking
  • Storage and network throughput testing
  • Multi-component load simulation
  • Power and thermal-performance validation

Stage 4: Stability & System Testing

  • Extended burn-in testing
  • Hardware-error and event-log review
  • Fan, temperature, and power monitoring
  • Final boot and configuration verification
