Genuine Dell OEM Replacement Board

This is a genuine Dell OEM right-side I/O controller panel for the Alienware m15 R3 laptop. It integrates the Killer 1650 WLAN card, two USB ports, and a micro SD card slot. The part arrives exactly as pictured and is identified by DPN 8G4J2.

Sustained Connectivity Performance

The on-board Killer 1650 WLAN card maintains wireless throughput during extended sessions. Both USB ports support continuous data transfer for attached peripherals. The micro SD slot provides reliable read and write cycles for media workflows.

Thermal and Power Characteristics

The board draws power directly from the laptop mainboard without an external supply. Passive cooling is handled by the system chassis airflow. No active fan or additional power connector is present on the daughterboard itself.

Questions about this item

Does the right-side IO panel with the Killer 1650 WLAN card add noticeable heat or fan noise during long sessions?

The board simply routes the existing wireless card and two USB ports; it has no active cooling of its own and draws minimal power, so it does not change the laptop's thermal profile.

Which internal connectors must already be present on the m15 R3 motherboard for this daughterboard to install?

The board plugs into the dedicated right-side IO header and uses the existing antenna cables for the Killer 1650 wireless module already mounted on the panel.

Will the micro-SD slot and USB ports on this replacement board work at the same speeds as the original factory part?

Yes, this is the genuine Dell OEM panel (DPN 8G4J2) with the same on-board Killer 1650 card and identical port wiring, so performance matches the factory specification.
