If the motherboard supports POWER OVER ESATA, you can directly connect the hard disk or optical drive with the ESATA cable and this board.<br> The introduction of the Power eSATA interface is undoubtedly a very good choice. "The ultra-fast fer rate and efficient protocol make ESATA the most powerful mainstream external storage connection method at present".<br> The interface on the host can be directly converted into a PowerOver eSATA interface, without occupying the PCI or PCI-E slot of the motherboard, just fix the riser card on the expansion slot of the chassis.<br> In total, the following functions can be implemented:<br> A: With the matching USB2.0 cable, you can turn out 2 USB ports.<br> B: Plug in the cable to turn out 2 PowerOver Esata ports, directly fer the to the outside, and no longer need to disassemble the case, you can directly connect 2.5-inch hard drives, 3.5-inch hard drives, 5.25-inch optical drives, etc.<br> Hardware Requirements:<br> One motherboard or riser card with interface<br> Precautions:<br> This adapter card does not need a driver. The test speed of the hard disk depends on the speed supported by the motherboard and the hard disk, and has to do with this adapter card. When connecting to , it depends on whether the motherboard supports ESATA. The motherboard must enable AHCI to support ESATA hot-plugging. If it does not support it, it be found after the device manager is refreshed. Some motherboards need to be restarted to find the device.<br> Please be aware.<br> This product is only a shared connector between the US port and the ESATA port. The US is provided by the 9PIN signal, not the port.<br> When using ESATA to use a US device, you must plug the matching US cable into the motherboard and the floppy drive power cable.<br> Colour: blue<br> Material: PCB+plastic+metal<br> Package Contents:<br> 1 * 9Pin USB Cable<br> 1 * 4Pin to Power Cable<br> 1 * Power eSATA Converter Card<br> <br
