1. The standalone expansion card cannot be used with a regular port. Using a regular port only recognize one drive! Do not even think about using it directly with the motherboard's port! It must be the dedicated matching card that comes with it (using the port converted by the ASM1061, ASM1064, or ASM1166 chip) to work! 2. It's only tested with the USB 3.0 to converter board we provide with PM functionality! Important points to note before purchasing: 1. This adapter card only supports use with ports with PM functionality, not motherboard ports! It is recommended for use with PCIe to expansion ports using chips (such as the ASM1064, ASM1166, etc.). If using a PCIe to converter card using a chip, you need to install a driver under . If you are using other operating systems, using the converter card is not recommended. 2. Please note that if using a PCIe to converter card using the ASM1061 chip, you also need to install a driver under . 3. Whether it can be used as a system drive depends on your motherboard, not the adapter card. 4. Only hard drives are supported; SAS hard drives are not supported! 5. Our store has only tested under WIN8 WIN10 WIN11 systems, and other operating systems have not been tested.
