NVIDIA Mellanox 930-9SPSU-00RA-00B 3KW AC Power Supply Unit (C2P Airflow): This is a 3000W AC hot-pluggable power supply module engineered for the NVIDIA Spectrum-4 800GbE switch family. The 930-9SPSU-00RA-00B uses Connector-to-Power (C2P) airflow, drawing air from the port side and exhausting through the PSU side. This is a chassis-specific PSU, not a generic server power supply. This is a refurbished unit.
Engineering Context
The 3KW capacity supports the dense power draw of 64x800GbE and 64x400GbE chassis under full load with optical transceivers in every port. C2P airflow matches the front-to-back orientation of standard hot-aisle/cold-aisle data center deployments where ports face the cold aisle. Hot-plug operation allows replacement without service interruption when paired with a redundant PSU. The unit ships with a power cord.
Deployment & Use Cases
Powering NVIDIA Spectrum-4 SN5400 (64x400GbE) and SN5600 (64x800GbE) switches in production. Replacement for failed PSUs in existing AI/HPC fabric switches. Adding redundancy to a single-PSU configuration. Supporting full-port-loaded switches in AI training clusters where every port carries an optical transceiver.

Compatibility & Hard Constraints
Compatible exclusively with NVIDIA Spectrum-4 SN5400 and SN5600 chassis that accept this PSU SKU. Airflow direction must match the rest of the chassis — do not mix C2P and P2C PSUs in the same switch. Not compatible with earlier Spectrum SN3000/SN4000 series PSU bays. Not a generic 3KW server PSU.
Why Choose T.E.S IT-SOLUTIONS
T.E.S IT-SOLUTIONS load-tests every PSU under sustained 3KW draw and verifies airflow direction labeling before shipment. We ship globally within 1–3 business days and provide guidance on PSU/airflow matching for SN5400/SN5600 deployments. Visit tes-itsolutions.com for our full catalog.
