Genuine Dell IO Board for Inspiron 5575 and 5570

This internal circuit board restores the SD card reader and USB ports on Dell Inspiron 5575 and 5570 laptops that do not have an optical drive. It is a direct OEM replacement part numbered PXH3Y, built to original specifications for reliable connectivity. The board suits repair technicians and owners fixing damaged card slots or faulty USB interfaces. Installation uses a direct ribbon-cable connection inside the chassis.

Ribbon-cable connection and multi-card support

The board connects directly to the motherboard via a ribbon cable, requiring no additional drivers for the card reader function. It reads SD, SDHC and SDXC memory cards up to 2 TB capacity. The USB 3.0 interface provides data transfer speeds up to 5 Gbps for efficient file management. ESD protection safeguards the circuitry against electrostatic discharge damage during handling and use.

Handles SD, SDHC and SDXC cards up to 2 TB

The reader comfortably manages standard, high-capacity and extended-capacity SD cards within the 2 TB limit. It runs out when a card exceeds that capacity or uses a format outside the SD family such as microSD without an adapter. The USB 3.0 link saturates at 5 Gbps, so large batch transfers will be limited by that bus speed. This part is not for laptops equipped with an optical drive.

Questions about this item

Will the ribbon cable or SD slot need replacement after heavy use?

The board connects by a direct ribbon cable and supports SD, SDHC and SDXC cards up to 2 TB; no user-serviceable wear items are identified for this part.

What limits sustained throughput on the card reader?

The USB 3.0 interface caps transfer speed at 5 Gbps, so that bus bandwidth is the first bottleneck during continuous large-file copies.

How much extra heat or power does the board add when the laptop runs all day?

As a passive internal circuit board with no active cooling, it draws minimal power and adds negligible heat inside the Inspiron 5575 or 5570 chassis.
