  • Wide 100–240 V input works worldwide

150W Replacement Adapter for Asus ROG

This 150W AC adapter replaces the original power supply for several Asus ROG laptops including the G73GX, GL503G, G72GX, G53J, G75VX, G75VW, G73JW, FX80G, FX50GE, N71Y and N73SV models. It delivers 19.5V at 7.7A through a 5.5mm by 2.5mm barrel connector. The unit is supplied new with a detachable mains cord included. Buyers whose laptops require the alternative 4.5mm by 3.0mm tip cannot use this adapter.

Thermals Noise and Power Draw

The adapter accepts a universal 100 to 240V input at 50 or 60Hz for worldwide use. Built-in protection circuits guard against short circuit, overvoltage, overcurrent and internal overheating during normal operation. No fan is present so the unit runs silently. The 150W output rating matches the original specification for the listed notebooks.

Build Quality and Connectors

The brick uses a fixed 5.5mm by 2.5mm DC plug; the A17-150P1A family also exists with a 4.5mm by 3.0mm variant so physical verification is essential before purchase. A standard IEC C5 cloverleaf mains lead is supplied for the AC side. The housing meets top industry safety standards and carries an 18-month worry-free warranty from the manufacturer.

Questions about this item

How do I install the 5.5×2.5 mm connector and what is the common mistake?

Plug the 5.5×2.5 mm barrel firmly into the laptop’s DC jack; the frequent error is confusing it with the 4.5×3.0 mm port that some A17-150P1A units also have, so verify the tip size before inserting.

What maintenance or replacement will this 150 W adapter need later?

The detachable IEC power cord can wear or be damaged over time and is the only user-replaceable part; the sealed adapter brick itself has no serviceable components.

What limit appears first when the adapter runs continuously at 19.5 V 7.7 A?

Internal overheating protection activates first under sustained full-load operation, shutting the unit down until it cools.
