HDX PCIe Card Power Adapter

This Sonnet adapter cable connects a 6-pin PCIe power source to the 4-pin socket on an Avid Pro Tools HDX PCIe card. It is built for users who install an HDX card inside a supported Sonnet expansion chassis. The cable supplies the auxiliary power the card requires for operation.

For Sonnet chassis owners with HDX cards

The adapter suits professionals adding an HDX card to an eGFX Breakaway Box, Echo Express III Thunderbolt 2 Edition, xMac mini Server or xMac Pro Server. It does not help builders using other chassis brands, cards with different power sockets, or systems lacking a 6-pin PCIe power output.

6-pin to 4-pin PCIe power conversion

The single decisive specification is the connector pairing: one 6-pin PCIe female plug on the supply side and one 4-pin plug for the HDX card. Without this exact adapter the HDX card cannot draw power from the listed Sonnet enclosures.

Questions about this item

What power limit does the HDX card itself impose when running continuously?

The HDX card's own 4-pin power socket and internal regulation determine the maximum draw, so the card's rated ceiling is the first limit reached during sustained use.

Does the adapter cable generate noticeable heat or noise inside an eGFX Breakaway Box during all-day sessions?

The passive cable has no active components, so it adds no fan noise and only minimal resistive warmth that stays well within the enclosure's normal operating temperature range.

Which host chassis must I already own for this cable to connect an HDX card?

You need a Sonnet eGFX Breakaway Box, Echo Express III Expansion System (Thunderbolt 2 Editions only), xMac mini Server or xMac Pro Server that provides an internal 6-pin PCIe power connector.
