Genuine Dell OEM IO Board for G3 3590

This genuine Dell OEM IO circuit board provides a direct replacement for the G Series G3 3590 laptop. It integrates two USB ports and one SD card reader slot onto a single daughterboard. The part carries Dell part number 52CHM and alternate reference SELEK_N18P_IO. It is intended for technicians or owners repairing a damaged port assembly.

Sustained reliability for daily peripheral use

As a passive circuit board, the unit contains no active cooling or power regulation that could degrade under load. Its USB ports and SD slot operate at the laptop's native bus speeds for as long as the host system supplies power. There are no thermal throttling concerns because the board generates negligible heat during continuous file transfers or device charging cycles.

Verify exact model match before ordering

This board fits only the Dell G Series G3 3590; other G3 chassis revisions or Inspiron models use different connectors and mounting points. Confirm the DPN 52CHM matches the label on your original board. Installation requires partial disassembly and comfort with ribbon-cable connectors; buyers without laptop repair experience should seek professional assistance.
