HPE 1600 W Flex Slot Platinum PSU
Exact model record for HPE identifier P01366-B21. 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 | HPE P01366-B21. Match all suffixes, assembly and revision markings on the actual label. |
|---|---|
| Form / rated output | Flex Slot hot-plug redundant server module; 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 rating). 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 at 200–240 V AC (1600 W class). +3.3 V / +5 V: +12 V system bus; standby rail and management contacts are Flex Slot-specific. Actual combined limits and auxiliary/standby outputs must be checked on the model-specific output table. |
| Connectors / system interface | Keyed HPE Flex Slot blind-mate output, hot-plug latch and status interface. |
| Mechanical envelope | 54.6 × 40.5 × 218 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 | 80 PLUS Platinum; operating input restrictions and supported chassis are system-guide-specific. 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
Use P01366-B21 only in listed chassis and AC conditions; do not infer cross-compatibility from shared Flex Slot dimensions. 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.
