Genuine ASUS ADP-280EB B Replacement Charger for ROG Strix SCAR 17 and ROG Zephyrus Duo

Original ASUS ADP-280EB B 280W AC Adapter for ROG Strix SCAR 17 & Zephyrus Duo – 20V 14A Genuine Gaming Laptop Charger

The ASUS ROG Zephyrus Duo and Strix Scar 17 are engineered to push the absolute boundaries of mobile computing. Whether you are driving the Zephyrus Duo’s revolutionary secondary ScreenPad Plus while rendering 3D models, or pushing 300+ frames per second in competitive arenas on the Scar 17, your hardware is operating under immense electrical load.

To keep the industry’s most powerful CPUs and unlocked RTX graphics cards running at their peak, a standard power brick won't suffice. You need the uncompromised, factory-grade power delivery of the Genuine ASUS ADP-280EB B 280-Watt Power Supply.

Engineered for Elite-Tier Hardware

When you invest in a premium, multi-thousand-dollar mobile workstation or gaming rig, the power adapter is the unsung hero protecting your investment.

The Dual-Screen & Desktop-Replacement Demand Laptops like the Zephyrus Duo draw significantly more power than standard gaming laptops simply to illuminate and process the secondary display. Furthermore, the Strix Scar 17 utilizes aggressive thermal profiles to push its Total Graphics Power (TGP) to the absolute maximum. This genuine 280-watt adapter delivers a flawless, continuous 14 Amps, ensuring that:

• Your system never has to throttle CPU/GPU clock speeds due to power starvation.

• Your battery isn't secretly draining while plugged into the wall during heavy gaming sessions.

• Your VRMs (Voltage Regulator Modules) receive a clean, stable sine wave of electricity, dramatically extending the lifespan of your motherboard.

The Hidden Costs of Counterfeit Chargers

The market is flooded with aftermarket "280W compatible" chargers that weigh half as much as the original. This weight discrepancy is a major red flag: it means the manufacturer stripped out the heavy copper heat sinks, essential EMI (Electromagnetic Interference) filters, and vital safety circuits.

Using a counterfeit adapter on a high-draw ROG laptop often leads to micro-stuttering in-game (due to voltage ripple), erratic touchpad behavior, or in worst-case scenarios, catastrophic power surges. The ADP-280EB B is an authentic OEM component, featuring ASUS’s strict internal architecture to prevent Over-Voltage, Over-Current, and Over-Temperature faults.
