Supermicro PWS-1K41P-1R
Supermicro PWS-1K41P-1R 1U redundant 1400 W 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
| Manufacturer identity | Supermicro PWS-1K41P-1R 1U redundant 1400 W PSU |
|---|---|
| Form factor / generation | 1U server hot-swap redundant PSU |
| AC input | 100–140 V AC/180–240 V AC, 50–60 Hz; full rating requires high-line operation. |
| DC output | 1400 W at 180–240 V, derated to 1100 W at 100–140 V; +12 V up to 116 A high-line, +5 VSB 4 A. |
| Dimensions / mounting | 76 × 336 × 40 mm 1U CRPS-style module for supported Supermicro systems. |
| Connectors | IEC mains inlet, blind-mate server output, PMBus 1.1 as model documentation specifies. |
| Revision distinctions | PWS-1K41P-1R input-range-dependent output; do not confuse 1R with SQ or use unsupported line voltage to claim 1400 W. |
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-1K41P-1R input-range-dependent output; do not confuse 1R with SQ or use unsupported line voltage to claim 1400 W.
Record module suffix, host qualification, airflow and input derating; only hot-swap with supported chassis redundancy.
