ADP-150CH D 150 W adapter

The Graviton ADP-150CH D is a 150 W AC adapter that delivers 20 V at 7.5 A through a 4.5x3.0 mm centre-pin connector. It accepts a 100-240 V 50-60 Hz mains supply and is certified to CE standard. The package includes the adapter and a detachable power cord with EU, US, UK or AU plug options.

For MSI GF76 owners needing a direct replacement

This unit matches the original ADP-150CH D part number supplied with the GF76 series. Buyers whose laptops require a different voltage, current rating or connector size should look elsewhere. The single fixed output makes it unsuitable for multi-voltage devices or universal charging scenarios.

The 4.5x3.0 mm centre-pin plug decides fit

Only laptops that specify this exact barrel diameter and centre-positive pin layout will connect securely. Verify the connector marking on the original charger or the laptop service manual before ordering.
