The ASUS RS520A-E13-RS12U is a 2U rack-mounted GPU server engineered around AMD's fifth-generation EPYC 'Turin' processor platform, delivering exceptional compute density for modern enterprise and AI infrastructure. Designed to support dual AMD EPYC 9005-series processors, the system provides a substantial number of CPU cores, high memory bandwidth via DDR5, and a PCIe 5.0 fabric that connects multiple high-performance GPUs with minimal latency. The architecture is purpose-built for workloads that demand tightly coupled CPU-GPU communication and large memory address spaces, making it a natural fit for large-scale inference, model training, and HPC simulation pipelines.
The RS520A-E13-RS12U accommodates up to 12 GPU accelerators in its 2U chassis, an unusually high GPU-to-rack-unit ratio that maximizes accelerator density without sacrificing thermal headroom. The platform supports PCIe 5.0 x16 slots, enabling full-bandwidth connectivity to modern data-center-class GPUs such as those from NVIDIA's Hopper and Blackwell families. ASUS integrates its ASMB server management controller for out-of-band IPMI 2.0 management, complemented by ASUS Control Center for fleet-level monitoring and firmware governance. A high-capacity, redundant power subsystem and an optimized airflow design maintain stable operation under sustained GPU workloads typical of production AI environments.
Targeted at datacenter operators, cloud service providers, and enterprise AI teams across the UAE, GCC, EMEA, and APAC regions, the RS520A-E13-RS12U is positioned as a scalable building block for GPU clusters and AI factories. Its support for DDR5 RDIMMs across a generous number of memory slots allows administrators to configure large in-memory datasets, reducing storage I/O bottlenecks during training and inference. The system's 2U form factor, combined with front-accessible drive bays and tool-less GPU installation where applicable, reduces operational overhead in high-density rack environments.

Reference servers include Dell PowerEdge XE9680 / XE9712, HPE Cray XD670, Lenovo ThinkSystem SR685a / SR675 V3, Supermicro AS-A21GE / SYS-821GE, Gigabyte G593 / G894, ASUS ESC. Share your target platform in the RFQ and we will confirm chassis-to-GPU compatibility and recommended NIC pairing.
Highly model-dependent. L40S / RTX-class: typically 3-6 weeks. H100/H200/B200 in SXM form factor: 12-16 weeks for whole-platform allocations. We quote genuine-channel ETAs only — no grey-market promises.
Yes — Omnixon stocks the full NVIDIA networking lineup (Quantum-2 / Quantum-X InfiniBand, Spectrum-X Ethernet, ConnectX NICs, BlueField DPUs) so we can quote a complete training-cluster BOM, not just the GPUs.
Yes. We hold genuine-channels for NVIDIA AI Enterprise software subscriptions. Add it to your RFQ and we quote node-aligned licensing along with the hardware.
