[ OEM / SERVER HOT-SWAP SUPPLIES // IDENTIFIED UNIT ]
Dell PowerEdge R740 1600 W PSU
Exact model record for Dell identifier D1600E-S0. Published ratings below are a model-family reference, not a substitute for the individual unit’s rating label and revision documentation.
SAFETY: Never open a PSU or probe its interior. Dangerous voltage can remain after unplugging; if damaged, wet, noisy, burned, or unstable, disconnect it and replace it with a verified compatible unit. For server hot-plug models, use only the host service procedure and confirm redundancy before removal.
Recorded model specifications
| Exact catalog identifier | Dell D1600E-S0. Match all suffixes, assembly and revision markings on the actual label. |
|---|---|
| Form / rated output | Hot-plug server module; redundant supply; manufacturer-rated total continuous output class: 1600 W. Peak/transient capacity, temperature derating, and combined-rail limits remain specification-revision dependent. |
| AC input rating | 200–240 V AC, 10 A, 50/60 Hz (high-line input). Region, temperature, and load may change the nameplate current; use the unit's own label for installation. |
| DC rail reference | Main +12 V rail: 133.3 A (1600 W class). +3.3 V / +5 V: +12 V high-current blind-mate output; auxiliary rails/control are system-specific. Actual combined limits and auxiliary/standby outputs must be checked on the model-specific output table. |
| Connectors / system interface | Dell keyed blind-mate backplane interface; not ATX/EPS cabling. |
| Mechanical envelope | 73.5 × 40.5 × 265 mm (width × height × depth where applicable). Check manufacturer's mounting drawing, screw locations, grille/fan clearance, cable bend radius, and chassis tolerances; never use nominal dimensions alone to force-fit a unit. |
| Standards / revision caveat | Efficiency and allowed configuration depend on R740 option table and input line; redundancy requires compatible module pair. Connector standards, efficiency certification, and mechanical form factor are different things. ATX, ATX12V, SFX, TFX, Flex ATX, and OEM interfaces are not interchangeable merely because they fit. |
Replacement & compatibility
- Read exact manufacturer model/SKU, DC output table, AC input, hardware revision, date code, and applicable service manual from the physical unit. The same family name can cover materially different revisions.
- For ATX-family units, confirm motherboard/EPS/PCIe connector count and pinout, total and per-rail limits, chassis size, clearances, and GPU transient/cable requirements. For proprietary OEM units, match the exact machine type, FRU/assembly number, keyed connector and service documentation.
- Use only modular cables explicitly qualified for this exact PSU model and revision. Modular PSU-side pinouts are not standardized; never transfer cables from a different supply based only on physical fit.
- Never use an unverified pin adapter to bridge proprietary pinouts. Replacing a PSU cannot correct a damaged motherboard, shorted load, or unsuitable mains circuit.
Revision and documentation notes
This is not the 1100 W D1100E-S0 already cataloged. Verify R740 service-tag, high-line requirement, firmware and matched module pair. Ratings shown are the source-backed nominal model reference; manufacturer documentation can change with regional SKU, revision, certification listing, or replacement part. Confirm all figures against the exact source manual and the PSU label before purchasing or servicing. AC/DC figures on this archive do not describe internal topology or guarantee used-unit condition.
