Dell PowerEdge R750xa 2U Rack Server
The Dell PowerEdge R750xa is a 15th Generation GPU-optimized 2U rack server designed for maximum GPU density. It supports up to four 300W double-width GPUs (NVIDIA A100, A30) or eight single-width GPUs in a 2U chassis, powered by 3rd Gen Intel Xeon Scalable processors with up to 80 cores total and 32 DDR4 DIMM slots.
Enterasource offers the R750xa configured to order. Each server is tested through our multi-point hardware diagnostic process and backed by a 2-year Enterasource warranty.
The R750xa is purpose-built for AI/ML training, HPC, GPU-accelerated rendering, and VDI at scale. Its 895mm chassis depth accommodates full-length GPU cards, with a minimum 1400W PSU and High Performance Gold fans required for GPU thermal management. Intel Optane PMem 200 Series support enables large in-memory datasets for GPU workloads. Optional Direct Liquid Cooling (DLC) enables high-density GPU deployments.

Frequently Asked Questions
How many GPUs does the Dell R750xa support?
Up to 4 double-width, full-height, full-length GPUs (such as NVIDIA A100 or A30) or up to 8 single-width GPUs. The R750xa is the most GPU-dense 15th Gen 2U server.
What is the difference between the R750xa and R750?
Both are 15th Gen 2U servers with the same processor and memory platform. The R750xa maximizes GPU density (4x DW vs 2x DW) but limits storage to 8 drive bays. The R750 offers up to 24 drive bays and broader storage flexibility. Choose the R750xa for GPU-first workloads, the R750 for general-purpose or storage-heavy workloads.
What generation is the Dell R750xa?
The Dell PowerEdge R750xa is a 15th Generation (15G) GPU-optimized server using 3rd Gen Intel Xeon Scalable processors.
How much does a refurbished Dell R750xa cost?
Pricing depends on processor, memory, GPU, and storage configuration. Enterasource builds every R750xa to order with a 2-year warranty and free ground shipping to the lower 48 states.
