Second PCIe expansion card slot provides power, yet fails to recognize connected USB devices.
Second PCIe expansion card slot provides power, yet fails to recognize connected USB devices.
This could be a simple issue, so don’t worry too much. Your RTX 3080 Ti is correctly seated in the top PCIe x16 port. You added an internal USB card in the second slot, but it doesn’t appear on any ports and isn’t receiving power. Since it’s only using the PCIe slot and not drawing power from SATA, you’ll need to check your motherboard’s BIOS settings—like power modes or device configurations. It might be related to how the system recognizes peripherals. If you’re having trouble with the layout, you may need to adjust the board’s configuration or consider a different port setup. Just let me know what you find!
