Right-Side USB 3.2 IO Board

This genuine Dell OEM replacement part provides two USB 3.2 ports on a daughterboard for the right side of G15 5510, 5511 and 5515 laptops. It is built specifically for units that shipped with the RTX 3060 graphics option. Install it to restore peripheral connectivity on a damaged or missing board.

USB 3.2 Port Limits

The board carries the USB 3.2 standard, so data rates and power delivery follow that specification. Only two ports are present on this assembly; no additional headers or internal connectors are included. Bandwidth is shared between the two ports when devices are used simultaneously.

Check Laptop Model and GPU

Verify your exact model number (5510, 5511 or 5515) and confirm it originally came with the RTX 3060 graphics configuration. Other GPU options in the same chassis use a different IO board part number and will not fit. Match the DPN TR4T5 to your service manual before ordering.
