  • 0x3.7mm DC connector matches original ADP-200JB D spec

Purpose and audience

This 200W AC adapter replaces the original ADP-200JB D charger for ASUS ROG Zephyrus G15 laptops including GA503, GA503QM, GA503QS and GA503QR models. It suits owners who need a new power supply for daily gaming or work sessions. Buyers who want more wattage or a different connector type should look elsewhere.

Sustained-load behaviour

The unit delivers 20V at 10A continuously across a 100-240V input range at 50-60Hz. V-0 grade flame-retardant materials and built-in OVP, OCP and SCP protections guard against voltage spikes, current surges and short circuits during extended use. Every adapter is tested before it leaves the supplier.

Installation and pitfalls

The package includes the adapter and a US power cord with a 6.0x3.7mm DC plug that must match the laptop port exactly. Verify the output rating and pin dimensions before ordering because an incorrect fit will prevent charging. No tools are required beyond plugging the cord into the wall and the connector into the laptop.

Questions about this item

Does the 200W adapter run hot or noisy when powering the Zephyrus G15 all day?

The unit is rated for 200W output with OVP, OCP and SCP protection and uses V-0 flame-retardant materials, so it handles continuous load without overheating.

What cable or connector must I already have to use this charger with my GA503?

The adapter terminates in a 6.0 mm by 3.7 mm DC barrel plug; your laptop must accept that exact pin size.

Can I keep my older 100-240V travel cord and just swap the brick?

Yes, the adapter accepts 100-240V 50-60Hz input, so any standard IEC C7 or C5 cord you already own will work worldwide.
