Q&A
Why does the device not function when only the 6-pin power connector is connected without also connecting the 4-pin or SATA-to-4-pin power adapter?
This is because the 6-pin power connector is a supplementary power source. Please connect either the 4-pin power connector or SATA power for proper operation.
