The NVIDIA Mellanox MTP005001 is a 1000W hot-swappable AC power supply unit for the Mellanox modular switch family, including the SX6536 chassis. This is NOT a server PSU and NOT a generic ATX supply; it is a chassis-specific module engineered for Mellanox director-style switching platforms with the matching connector, voltage rail, and form factor. MPN: MTP005001. Condition: Refurbished, load-tested at T.E.S IT-SOLUTIONS.
Engineering context. The MTP005001 delivers 1000W of stable AC power to the SX6536-class chassis backplane. Multiple PSUs are typically deployed for N+N or N+1 redundancy so that a single PSU failure does not bring down the chassis. The unit is hot-pluggable, and the PSU bay is keyed to prevent reverse insertion. Protective circuitry covers over-voltage, over-current, and thermal events.
Deployment and use cases. Used to power FDR/EDR-class Mellanox modular director switches that drive HPC fabrics, large InfiniBand SAN backbones, AI training spines, EDA grids, and any chassis where a PSU has failed and needs hot replacement without scheduling a maintenance window.
Technical specifications:
- Model: MTP005001
- Type: AC hot-swappable PSU module
- Power rating: 1000W
- Form factor: chassis-specific PSU bay
- Compatibility: Mellanox modular switch family, including SX6536

Compatibility and constraints. Compatible with the Mellanox modular switch family chassis it is rated for, including the SX6536. NOT compatible with fixed-form 1U/2U switches such as the SX6018 or with HDR/NDR-generation modular chassis that use different PSUs. AC input only — verify your chassis PDU and inlet voltage before installation. Buyer is responsible for confirming chassis hardware revision and existing PSU pairing.
Why TES. T.E.S IT-SOLUTIONS load-tests every refurbished MTP005001 and inspects the connector and fan path before shipment. Standard handling time is 1–3 business days. See tes-itsolutions.com for additional Mellanox modular spares including switch blades, fan trays, and management modules.
