NVIDIA Mellanox MTEF-PSR-AC-A 460W AC Power Supply, C2P Airflow: This is a hot-swappable AC power supply module (NVIDIA P/N 930-9BPSU-00JF-000) for NVIDIA Mellanox 1U Ethernet and InfiniBand switch chassis. It is a 460W field-replaceable PSU, not a complete switch and not a DC unit. The C2P (Connector-to-Power) airflow direction means air enters from the port side and exits through the PSU side. This is a refurbished unit, tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MTEF-PSR-AC-A delivers 460W of AC-input power for Mellanox 1U switch chassis that ship with redundant N+N PSU bays. It supports hot-swap so an operator can replace a failed PSU without bringing the switch offline. The C2P airflow direction must match the airflow direction of the fan modules in the chassis; Mellanox does not support mixed airflow directions within a single switch. The PSU includes integrated cooling fans and exposes status via the chassis management interface.
Deployment & Use Cases
Replacement PSU for Mellanox 1U Ethernet and InfiniBand switches deployed as Top-of-Rack aggregation in HPC, AI training fabric, and enterprise data center pods. Spare PSU inventory for N+N redundancy maintenance. RMA replacement for failed units. Lifecycle refresh for switches in active production where original PSUs have reached end-of-warranty.
Technical Specifications

Part Number: MTEF-PSR-AC-A
NVIDIA P/N: 930-9BPSU-00JF-000
Type: Hot-Swap Power Supply Unit
Power Output: 460W
Input: AC
Airflow: C2P (Connector-to-Power)
Form Factor: 1U PSU Module
Application: Mellanox 1U Switch Systems
Condition: Refurbished
Compatibility & Constraints
Compatible with NVIDIA Mellanox 1U switch chassis that accept the MTEF-PSR series and are configured for C2P airflow. Must be paired with matching C2P fan modules in the same chassis. Not compatible with chassis configured for P2C (reverse) airflow without changing fan modules. Not a DC-input unit; do not connect to 48VDC power feeds. Specific switch model compatibility should be verified against the Mellanox PSU compatibility matrix before deployment.
