USB Bus Power Input

12V Step-Down to 5V from either PCIe 12V or Power Connector 12V (ATA 4-pin or SATA 15-pin)

The USB Bus power (5V) are step-down from 12V and the 12V input might from either PCIe Edge Connector or Auxiliary Power Connectors (J1 & J2).
Note:
If the PCIe Slot can’t supply 12V current high enough then you have to attach the Auxiliary Power from either J1 (ATA 4-pin) or J2 (SATA 15-pin).

Computer Platform

Computer with PCI Express slot ( x8, x16)

Note:
For the best performance, It should be installed in a PCIe Gen 3 compliant slot in the host computer.
