G3 15 3579 power replacement

This 130W AC adapter is built for the Dell G3 15 3579 and uses a 7.4mm barrel connector that matches the original jack. It delivers 19.5V at 6.7A to charge the internal lithium-ion battery and run the laptop simultaneously. Owners of other Dell models with different tip sizes or wattage requirements should verify compatibility before purchasing.

Thermals noise and power draw

The brick draws up to 130 watts from the mains and converts it to the regulated 19.5V output used by the G3 15 3579. During typical office work or video playback the adapter runs warm but remains within normal operating temperature. No fan is present so operation is silent in everyday use.

Sustained load behaviour

Under continuous heavy load such as gaming or rendering the adapter maintains its rated 19.5V 6.7A output without throttling. The unit is designed to sustain the full 130W output for extended periods while keeping surface temperatures within safe limits. Users running prolonged maximum-performance sessions can rely on stable power delivery.

Questions about this item

How do I install the 7.4mm barrel tip on my G3 15 3579 and what step is often missed?

Align the 7.4mm barrel tip with the laptop charging port, push firmly until it seats fully, then plug the adapter into mains power; the step often missed is confirming the tip is fully seated before powering on.

What maintenance or replacement will the CY0JM adapter need over time?

The adapter itself has no user-serviceable parts; keep the 7.4mm connector clean and the cable free of sharp bends, and replace the unit if output drops below 19.5 volts or 6.7 amps.

What limit appears first when the 130W adapter runs continuously at full load?

Sustained 130-watt output will hit thermal limits first; the brick will throttle or shut down if its internal temperature rises beyond safe operating range.
