DELL PowerEdge R650xs 1U Rack Server 2x Xeon Silver 4316 2.3GHz 20 Core 64GB DDR4 H745 10 Bay 2.5

Compact 1U density for virtualised workloads

The Dell PowerEdge R650xs is a 1U rack server fitted with two Intel Xeon Silver 4316 processors running at 2.3 GHz with a 3.4 GHz turbo and 20 cores each. It ships with 64 GB of DDR4 2666 MHz registered ECC memory across four modules. The PERC H745 RAID controller with 4 GB NV cache manages up to ten 2.5 inch SAS or SATA drive trays. A Broadcom 5720 quad-port 1 GbE OCP 3.0 card and iDRAC9 Enterprise remote management complete the baseline specification.

Dual 1400 W platinum supplies share the load

Redundant hot-swap power supplies rated at 1400 W each operate at platinum efficiency, allowing one unit to carry the full load if the other fails. The 1U chassis uses front-to-rear airflow tuned for dense rack rows; fan speeds scale with CPU and inlet temperature to keep acoustic output predictable in normal operation. Power draw varies with processor utilisation and drive count, but the dual-supply design keeps headroom available without requiring external load balancing.

Ten drive bays and OCP networking leave PCIe slots

The front-loading 2.5 inch trays accept SAS or SATA media while the OCP 3.0 mezzanine carries the quad-port 1 GbE adapter, freeing standard PCIe slots for additional controllers or accelerators. iDRAC9 Enterprise provides dedicated out-of-band management over a separate network connection. Builders needing NVMe or GPU expansion must verify riser and cable kits separately, as the base configuration prioritises storage density and network connectivity over extra full-height cards.
