Purpose & Audience

This 150W AC adapter replaces the original charger for a wide range of Asus laptops including the K571, M6500, M7600, N7600, Q530, Q539, Q540, UM535, UX535, UX550 and UX580 series. It suits owners who need a direct replacement or a spare unit that matches the factory voltage and current ratings. Builders who require a different tip size or a higher wattage unit will not find a match here.

Thermals, Noise & Power

The adapter accepts a worldwide AC input of 100 to 240 volts at 50 to 60 hertz and delivers up to 150 watts at 20 volts and 7.5 amps, with alternative 19.5 volt 7.7 amp and 19 volt outputs supported. Overload, short-circuit, over-voltage, over-current and over-temperature protections manage heat and safety during normal operation. No fan is present, so the unit runs silently.

Build Integration

A 4.5 mm diameter barrel plug with a centre pin connects to the laptop, while a six-foot UL-listed three-prong AC cord and a six-foot DC cord provide generous reach. The durable, sealed case resists water and humidity, allowing the adapter to sit on a desk or travel in a bag without extra protection. Buyers needing a right-angle connector or a USB-C output must look elsewhere.

Questions about this item

How do I install the 4.5 mm tip with center pin on my Asus laptop?

Align the center pin with the laptop's charging port and push the 4.5 mm plug straight in until it seats firmly; the step people miss is forcing it at an angle, which bends the pin.

Will the 6 ft AC cord or 6 ft DC cord need replacement first?

The DC cord sees repeated flexing at the laptop end and typically wears before the stationary AC cord; inspect both for fraying after extended use.

At what load does the 150 W adapter hit its thermal limit during sustained use?

Continuous output at 20 V 7.5 A (150 W) triggers the built-in over-temperature protection first, causing the unit to throttle or shut down until it cools.
