HPE 750 W Common Slot Platinum Plus Hot Plug PSU Kit (656363-B21)
Exact module identity: HPE 656363-B21. This record applies only to this manufacturer option/PID; nominal wattage or a similar shell does not prove cross-model compatibility.
HIGH-VOLTAGE WARNING: Disconnect mains before external inspection. Never open a PSU. Internal capacitors may retain lethal charge after unplugging. Do not probe or repair its interior; use qualified service or replace the unit.
Model-specific ratings & fit
| Manufacturer identity / exact module | HPE 656363-B21 — HPE 750 W Common Slot Platinum Plus Hot Plug PSU Kit (656363-B21) |
|---|---|
| Rated output / rail information | 750 W; +12 VDC main rail (750 W class); standby output and continuous rail limits are as specified on the exact module label. |
| AC input | 100–240 V AC, 50/60 Hz; rated output and line derating are nameplate/system dependent. |
| Efficiency | 80 PLUS Platinum Plus class; exact efficiency varies with load and input |
| Form factor / mounting | HPE Common Slot hot-plug module; mechanically distinct from Flex Slot and M-CRPS. |
| Connectors / backplane | IEC AC inlet; proprietary HPE Common Slot blind-mate connector to the server power backplane. |
| System compatibility | Select HPE ProLiant Common Slot Gen8 platforms whose system QuickSpecs list option 656363-B21; a Common Slot name does not establish fit in Flex Slot/M-CRPS bays. |
| Redundancy / cooling | Hot-plug and 1+1 redundancy require the host to support paired Common Slot modules and retain sufficient capacity; chassis-specific airflow. |
| Revision distinctions | Confirm exact 656363-B21 kit and PSU label. Different Common Slot wattage/efficiency models may be disallowed as a redundant pair; follow the host service manual. |
Compatibility & safe installation
- Confirm full manufacturer part/PID, revision and label against the host’s exact system QuickSpecs, service manual and power-supply matrix.
- Check input voltage, rail limits, connector/backplane keying, bay dimensions, supported efficiency class and cooling direction before installation.
- Hot-plug is conditional: verify healthy remaining supply capacity, supported redundancy state and the host service procedure before removing a live module.
- Do not mix modules or use modular leads across models unless the system manufacturer explicitly approves that combination.
- Never open or probe a PSU. Retire damaged, wet, burnt, corroded, modified or unidentified units.
Revision & archival notes
Confirm exact 656363-B21 kit and PSU label. Different Common Slot wattage/efficiency models may be disallowed as a redundant pair; follow the host service manual.
Archive a clear nameplate photograph, complete option/FRU number, hardware revision, AC inlet and connector labels, host model, and source-document revision. Distinguish manufacturer ratings from derived values.
