ASUS Triple Display USB-C Dock DC300 - 12 Ports, 90W PD
The ASUS Triple Display USB-C Dock DC300 is a 12-port docking station designed for laptop users who need to connect multiple displays, peripherals, and network devices through a single cable.

Why this product
Three 4K displays from one dock

USB 3.2 Gen 2 ports on both USB-C and USB-A deliver up to 10 Gbps, moving large files four times faster than USB 3.0.
Eight simultaneous device connections

Best for
- Remote workers and office professionals who need a clean desk with multiple monitors and peripherals.

Trade-offs

- Setups requiring more than 90W of charging power for connected devices.
- Users needing more than 12W of power delivery through the USB Type-A port.
- Cable management in very tight spaces; the 65cm cable and dock footprint (160 × 80 × 32 mm) require moderate desk depth.
