## Long description

The Sonnet TCB-HDXB is a specialized power adapter cable engineered specifically for the Avid Pro Tools HDX PCIe card.

Connector type: 6-pin to 4-pin PCIe power adapter
Compatibility: Avid Pro Tools HDX PCIe cards

How to use
To install the cable, first ensure that your computer or expansion chassis is powered off and disconnected from the mains. Locate the internal 6-pin PCIe power connector within your expansion system and plug the corresponding end of the Sonnet TCB-HDXB cable into it. Connect the other end, which features the 4-pin connector, directly into the power socket on your Avid Pro Tools HDX card. Ensure both connections are firmly seated before powering on your system.
What to consider before purchase
Verify that your expansion chassis is one of the supported models listed
Confirm your Avid Pro Tools HDX card requires a 4-pin auxiliary power input
Ensure there is sufficient physical space within your chassis for the cable routing
Usage recommendations
Always verify that the power cable is fully inserted into both the expansion chassis power source and the HDX card to prevent intermittent power loss or potential damage to the hardware components.
