Compatible Sony models

This 19.5V 3.96A 75W AC adapter fits Sony PCG-R505DMH, PCG-R505DS, PCG-R505DSK, PCG-R505DSP and PCG-R505Dx laptops. It replaces the original power supply with a matching 6.5mm*4.4mm barrel connector. The package includes the adapter and a country-specific power cord. It is not for owners of other Sony series or different connector sizes.

Worldwide input range and thermal load

The unit accepts AC input from 100 to 240V at 50 to 60Hz, making it suitable for international travel. During normal operation it delivers a steady 19.5V at 3.96A for a total of 75W. The external brick design dissipates heat passively without a fan, so acoustic noise is absent in typical office use.

Sustained delivery under continuous load

Under sustained load the adapter maintains its rated 19.5V 3.96A output without throttling. The 24-month warranty period reflects the manufacturer's confidence in long-term reliability. It is not for users who need a higher wattage unit for docking stations or discrete graphics configurations.

Questions about this item

How do I connect the 6.5mm by 4.4mm barrel plug to my Sony PCG-R505DMH?

Align the centre pin with the laptop socket, push the barrel straight in until it seats firmly, then plug the supplied cord into a 100 to 240V 50 to 60Hz mains outlet.

Which parts of this 75W adapter will need replacing after long use?

The detachable mains cord and the DC cable near the barrel plug are the items most likely to wear out; the brick itself has no user-serviceable components.

At what load does the 19.5V 3.96A output hit its thermal limit?

Continuous draw at the full 3.96A (75W) rating will cause the unit to reach its design temperature ceiling first; sustained operation above that level is not supported.
