Supplies auxiliary power to high-performance GPUs installed in slot 34 of a PowerEdge R750XA server via a 16-pin split cable
This genuine Dell NX4N2 cable delivers dedicated auxiliary power to high-performance GPUs installed in Slot 34 of the PowerEdge R750XA server. It connects directly to the system board via a 16-pin interface and splits into two 8-pin PCIe connectors. The enterprise-grade build ensures a secure, tool-less fit for professional workloads.
The split design provides two standard 6+2 PCIe connectors from a single 16-pin source, supporting graphics cards that require dual 8-pin power inputs. This configuration handles the high-wattage demands of professional GPUs used in AI, machine learning, virtualization, and HPC tasks. It runs out when a GPU requires more than two 8-pin connections or a different connector standard.
The cable is keyed exclusively for Slot 3 and Slot 4 positions within the R750XA chassis, drawing power directly from the system board. It cannot be used in other server models, chassis slots, or standard desktop power supplies. The proprietary 16-pin board interface prevents adaptation to generic PSU cables or third-party GPU risers.

Yes. The NX4N2 cable connects directly to the system board and splits into two 8-pin PCIe plugs, so you can power a high-wattage GPU in slot 34 using the existing power infrastructure.
The tool-less, direct-fit connectors click firmly into the system board and the GPU’s 8-pin sockets; a secure fit with no visible gap indicates proper engagement.
Only the 16-pin split power cable is supplied; the graphics card and any additional brackets or screws must be purchased separately.
