Supermicro PWS-920P-SQ 920 W redundant PSU
Supermicro PWS-920P-SQ 920 W hot-swap redundant server power module. This record applies only to the model and generation named here; similar wattage or connector shape does not establish equivalence.
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 | Supermicro PWS-920P-SQ 920 W hot-swap redundant server power module |
|---|---|
| Form factor / generation | Server hot-swap / 1U SQ module |
| AC input | 100–240 V AC, 50/60 Hz, 11–5.5 A; verify nameplate for line derating. |
| DC output | +12 V 76 A, +5 V standby 4 A; total 920 W rating. Verify exact label and system cooling conditions. |
| Dimensions / mounting | 1U hot-swap module for approved Supermicro chassis and backplane; SQ means Super Quiet family, not ATX. |
| Connectors | IEC input; proprietary blind-mate chassis output. Use only in Supermicro systems qualified for the exact PWS part. |
| Revision distinctions | PWS-920P-SQ is distinct from 920P-1R and other suffixes; suffix affects acoustic/thermal and system qualification. |
Compatibility & safe installation
- Confirm complete model, suffix, region and revision against the unit nameplate and manufacturer manual. Do not substitute by wattage or connector-shell appearance.
- Verify AC range, per-rail and combined DC ratings, line derating, pinout, dimensions, cooling direction and qualified host support.
- Modular cables have model- and revision-specific PSU-side wiring. Use only approved leads for this exact PSU; a plug that fits may have a dangerous pinout mismatch.
- For redundant/hot-plug modules, follow the host service manual, redundancy requirements and supported replacement procedure. A server blind-mate module is not an ATX supply.
- Never open or probe a PSU. Retire damaged, wet, burnt, corroded, modified or unidentified units.
Revision & archival notes
PWS-920P-SQ is distinct from 920P-1R and other suffixes; suffix affects acoustic/thermal and system qualification.
Preserve compatible chassis list, airflow direction, module revision and partner-PSU configuration. Hot-swap only under the system procedure.
Archive the complete nameplate, part/spare number, manufacturing date/revision, region, connector/cable labels, mounting orientation, source document and its issue date. Separate label transcription from testing.
