ASUS ExpertCenter Pro ER100A B6 AMD EPYC 4000 1U Rack
The ASUS ExpertCenter Pro ER100A B6 AMD EPYC 4000 1U Rack is a compact rack workstation built for small- to medium-sized businesses that need server-grade reliability and management in a single rack unit. It supports AMD EPYC 4000 series processors alongside Ryzen 7000 and 9000 series, combines flexible storage and PCIe 5.0 expansion with onboard BMC remote management, and fits deployments where space is limited but workload demands are not.
Why this product
AMD EPYC 4000 series processor support
It accepts AMD EPYC 4004 and 4005 series processors, as well as Ryzen 7000 and 9000 series, supporting up to 16 cores, 32 threads, and a maximum frequency of 4.5 GHz with a 120 W TDP.
DDR5 ECC memory for data integrity
Four DIMM slots support DDR5 5600 MHz ECC or non-ECC UDIMM modules, giving workloads that require error correction the memory reliability they need.
Flexible hot-swap and internal storage
Two hot-swappable 2.5" SATA bays allow drive changes without powering down, while two additional internal 2.5" SATA or NVMe U.2 drive trays and one M.2 PCIe 5.0 x4 slot expand capacity further.
GPU support for rendering and AI workloads
It accommodates up to one NVIDIA RTX A1000 or RTX A400 low-profile graphics card, making it suitable for rendering tasks and AI inference in a 1U form factor.
Onboard BMC and ASUS Control Center Express
A dedicated Realtek 1Gb management LAN connects to an onboard Aspeed AST2600 BMC for IPMI remote management, complemented by ASUS Control Center Express software for real-time monitoring.
PCIe 5.0 x16 expansion slot
A single full-height half-length PCIe 5.0 x16 slot provides high-bandwidth connectivity for graphics cards or other expansion cards, with actual link speed varying by CPU type.

- SKUASU-4194
- EAN4711636149068
- Compatible with AMD EPYC 4004 and 4005 series processors in an AMD Socket AM5 / AMD B650 chipset platform.
- Also compatible with AMD Ryzen 9000 and Ryzen 7000 series processors; refer to the ASUS CPU support list at asus.com for the full list.
- Supports standard 2.5" SATA drives in hot-swap bays and 2.5" NVMe U.2 drives in internal trays, plus M.2 2242/2260/2280 Key-M drives.
- Supports NVIDIA RTX A1000 and RTX A400 low-profile GPUs; other low-profile cards may be supported but ASUS lists only these two specifically.
- Supported operating systems differ by CPU family: EPYC 4005 supports Windows Server 2025/2022 or Ubuntu 24.04; EPYC 4004 supports Windows Server 2022 or Ubuntu 22.04; Ryzen 9000/7000 supports Windows 11 Pro or Ubuntu 24.04.
- Not compatible with processors outside the AMD AM5 socket ecosystem — Intel processors and older AMD platforms are not supported.
Best for
- SMB IT departments that need server-grade remote management (IPMI/BMC) and real-time monitoring without deploying a full tower or 2U server.
- Space-constrained rack deployments where a 1U height (43.2 mm) is required but multi-drive storage and PCIe expansion cannot be sacrificed.
- Rendering and AI inference workloads that benefit from optional NVIDIA RTX A1000 or A400 GPU support alongside a high-core-count AMD EPYC processor.
- Storage-flexible environments needing a mix of hot-swap SATA, internal U.2 NVMe, and M.2 PCIe 5.0 storage all in one unit.
- Teams requiring ECC memory for workloads where data integrity is critical, supported via DDR5 5600 MHz ECC UDIMM slots.
Trade-offs
- High-density multi-GPU deployments: it supports only one low-profile GPU and has a single PCIe 5.0 x16 slot, so workloads requiring multiple full-height or double-width cards are not served.
- Dual-processor configurations: this is a single-processor platform with one AM5 socket; workloads that scale across two physical CPUs require a different platform.
- Power-constrained environments without access to 100–240 Vac mains power, as the 500 W ATX PSU requires a standard AC supply.
- Large-scale storage arrays: the maximum of four drive positions (two hot-swap SATA bays, two internal U.2 trays) and one M.2 slot limits total raw storage capacity compared to storage-optimised platforms.
