The PowerEdge R750xa is Dell's dedicated GPU-accelerated 2U server, built to take on the compute demands of AI/ML training and inferencing, high-performance computing and GPU-dense virtualisation. Where a general-purpose 2U server compromises on GPU headroom to save space for drives, the R750xa is designed around the accelerator first — front-loaded GPU bays, PCIe Gen4 throughout, and cooling engineered for double-width cards at full power.
At a glance
Typical deployments
AI/ML training and inferencing
This is what the R750xa was built for. Prioritise GPU count and wattage class over CPU core count — the platform supports up to four double-width 300 W cards, so check your workload's model size and batch requirements against the GPU configuration before the CPU spec.
High-performance computing
HPC clusters benefit from the combination of high core-count Xeon processors and PCIe Gen4 bandwidth to accelerators. Look at DIMM population and speed carefully — memory bandwidth per core often matters more than raw capacity for tightly-coupled HPC codes.
GPU-dense virtualisation
For virtual desktop or GPU-accelerated VDI environments, prioritise total memory capacity — up to 4 TB with LRDIMMs — over clock speed, since consolidation ratios are usually capacity-bound rather than compute-bound.
Database and licensed workloads
If you're running per-core licensed database software, fewer, faster cores keep licensing costs down. Choose a lower core-count, higher clock-speed Xeon configuration rather than the maximum 40-core option.
NVMe-heavy storage tiers
With up to 6 x 2.5" NVMe drives direct-attached and PCIe Gen4 throughout, the R750xa suits latency-sensitive storage tiers ahead of a SAN, though this configuration trades off some front-bay GPU capacity.

Frequently asked questions
What does "refurbished" mean for this server?
It means the unit has previously been deployed, then removed, tested and reconditioned by us before resale. Components are checked for function and wear, and the configuration is verified against the specification you order.
Is a refurbished R750xa suitable for production use?
Yes — these are enterprise-grade servers designed for continuous datacentre operation, and refurbishment doesn't change that duty rating. Many customers run refurbished PowerEdge hardware in production for GPU compute, virtualisation and database workloads.
What's included with the server?
What's included depends on the specific listing — processors, memory, drives, GPUs, rails and power supplies vary by configuration. Check the individual product page for the exact build, and contact us if you need something specific.
Can I upgrade the memory, storage or GPUs later?
The R750xa platform supports up to 32 DDR4 DIMMs, up to 8 SAS/SATA/NVMe drives and multiple GPU configurations, so there's room to scale. We can also help source compatible upgrade components for units purchased from us.
Can you configure the server to a specific build before shipping?
Yes, we can build to a specified processor, memory, drive and GPU combination within the R750xa's supported configurations. Get in touch with your requirements and we'll confirm availability and pricing.
Which GPUs does the R750xa support?
The platform accommodates up to four single-width 150 W or four double-width 300 W GPUs in the front bays, plus two single-width 75 W cards at the rear. Confirm your specific GPU model's compatibility with us before ordering.
