Replacement 330 W AC adapter for MSI GT72 and GT72S

This 19.5 V 16.9 A power supply replaces the original MSI PA-1331-91 unit. It delivers 330 W through a 7.4 mm × 5.0 mm barrel connector with a central pin. The adapter accepts 100-240 V input at 50-60 Hz for worldwide use. It is sold new with a detachable power cord included.

Upgrading from a lower-wattage or damaged charger

A 330 W unit is required when the original adapter has failed or when a lower-rated charger cannot sustain full performance under load. The jump is worth it if your laptop shuts down during gaming or heavy workloads because the previous brick could not supply enough current. Matching the exact voltage, amperage and connector ensures stable operation without throttling.

Verify your laptop's original specifications

Confirm that your MSI GT72 or GT72S originally shipped with a 19.5 V 16.9 A 330 W adapter and the 7.4 mm × 5.0 mm centre-pin connector. Check the label on your old brick for the PA-1331-91 part number and identical output values. Using a mismatched voltage or connector can damage the laptop's power circuitry.

Questions about this item

Will the 7.4 mm × 5.0 mm connector with central pin fit my MSI GT72 or GT72S charging port?

Yes, the adapter uses a 7.4 mm by 5.0 mm barrel plug with a centre pin that matches the original MSI GT72 and GT72S DC-in jack.

What is the correct order to connect the 19.5 V 16.9 A adapter so the laptop recognises it?

Plug the AC cord into the brick first, then into a 100–240 V 50–60 Hz wall outlet, and finally insert the 7.4 mm × 5.0 mm DC plug into the laptop; reversing the sequence can prevent detection.

When should I replace the supplied IEC power cord on this 330 W adapter?

Replace the cord if the insulation cracks, the plug pins bend, or the connector becomes loose, as a damaged cord can interrupt the 19.5 V 16.9 A supply to the laptop.
