MSI MEG Ai1300P PCIE5
MSI MEG Ai1300P PCIE5 1300 W fully modular PSU. 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.

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
Original Ai1300P PCIE5 is ATX 3.0/12VHPWR era, not a later ATX 3.1 model. Seat GPU plugs fully and follow bend-clearance advice.
Record regional label, cables and MSI specification/manual revision; package connector population can vary.
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.
