Supermicro PWS-1K23A-SQ
Supermicro PWS-1K23A-SQ 1U redundant Titanium PSU. This entry covers the specific model or bounded historical system assembly identified here; suffixes and supplier revisions are not presumed equivalent.
HIGH-VOLTAGE SAFETY: Disconnect mains before external inspection. Never open a PSU. Internal capacitors can retain dangerous charge after disconnection. Do not probe or repair its interior; use qualified service or replace it.
Model-specific ratings & fit

| Connectors | IEC AC inlet; 19-pair blind-mate gold-finger output; PMBus 1.2. Not ATX cabling. |
| Revision distinctions | PWS-1K23A-SQ is SQ Titanium model; voltage-dependent max differs materially from 1200 W headline. |
Compatibility & safe handling
- Verify full model, suffix, region and revision using the actual unit nameplate and matching manufacturer manual. Wattage and plug shape alone do not establish compatibility.
- Check AC input range, rail and combined output limits, derating, signaling/pinout, cooling direction, mounting and system qualification before installation.
- PSU modular-side cables are model-specific. Never reuse an unapproved lead; a matching plug can carry a different pinout.
- Server hot-plug is permitted only in qualified host configurations and under the host’s documented redundancy/live-service procedure.
- Never open or internally probe the supply. Retire damaged, wet, burnt, corroded, modified or unidentified units.
Revision & archival notes
PWS-1K23A-SQ is SQ Titanium model; voltage-dependent max differs materially from 1200 W headline.
Preserve label and input-mode derating, PMBus/host support and chassis compatibility list; use redundant replacement procedure.
Photograph the full nameplate, model/FRU, supplier, revision/date code, line selector, cable ends, mounting orientation and source-document issue. Keep observed label data separate from test results.
