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.
