Power for ROG Strix G15

This 240W AC adapter delivers 20V at 12A through a 6.0x3.7mm DC connector. It is built as a direct replacement for the ADP-240EB unit shipped with compatible ROG Strix G15 G513 series notebooks. The unit accepts 100-240V input at 50-60Hz for worldwide mains compatibility.

Fits into the charging loop

The adapter connects between a standard IEC C5 mains lead and the laptop's barrel jack, freeing the internal battery from discharge during heavy workloads. It requires a matching 6.0x3.7mm tip on the notebook side and a grounded wall outlet on the other. No extra cables or converters are included beyond the supplied US power cord.

Sustained delivery with protections

Under continuous load the brick maintains its rated output while V-0 grade flame-retardant housing and built-in OVP, OCP and SCP circuits guard against voltage spikes, over-current events and short circuits. Every unit is tested before shipment to confirm stable 240W performance over extended sessions.

Questions about this item

Will the 240W rating handle continuous gaming loads without tripping?

The adapter delivers 20V at 12A for a full 240W output, and built-in over-current and short-circuit protections keep it stable during sustained high-draw sessions.

Does the brick stay cool and quiet when the laptop runs all day?

V-0 grade flame-retardant materials and the protection circuitry limit heat buildup, so the unit runs quietly without a fan even under continuous load.

What must I already have for this charger to work with my ROG Strix G15?

Your laptop must use a 6.0×3.7 mm DC jack and accept 20V input; the package includes a US power cord, so only a wall outlet is needed.
