Innocard SFF-8673 PCIe 4.0 Adapter
This Innocard adapter converts a single SFF-8673 1x2 4X PCIe 4.0 interface into two U.2 NVMe SSD ports. It is built for users adding high-speed storage to servers or workstations that expose a Mini SAS HD connection. The board integrates dual U.2 SFF-8639 connectors and dedicated 12 V hot-plug power circuits with eFuse protection.
Check host connector and power budget
Verify that your system provides an SFF-8673 1x2 4X port wired for PCIe 4.0 at 16 GT/s and that the backplane can supply the required 12 V and 3.3 V rails. The on-board eFuse limits each port to a programmable 6.5 A current limit with controlled inrush slew rate. Ensure your chassis accommodates the dual U.2 drive height and that the SMBus hot-swap buffer matches your platform management.
Thermals noise and power behaviour
The adapter has no active cooling; thermal performance depends on chassis airflow across the PCB and installed SSDs. Hot-plug power circuitry includes thermal shutdown protection and fault alert signalling to prevent damage during sustained loads. Green LEDs indicate power-ready status while red LEDs show drive activity and inverted PERST#, WAKE# and CLKREQ# states. Power draw scales with the attached NVMe drives and their workload.

Questions about this item
Does the Innocard SFF-8673 adapter include the U.2 NVMe SSDs or must they be purchased separately?
The adapter provides two U.2 SFF-8639 connectors and dual 12V hot-plug power with eFuse protection. The U.2 NVMe SSDs themselves are not included and must be bought separately.
What PCIe generation does the SFF-8673 1x2 connector support for each U.2 port?
The internal SFF-8673 1x2 connector runs at PCIe 4.0, delivering a 16GT/s link that is split across the two U.2 ports for NVMe 1.4 drives.
How do the onboard LEDs show that a U.2 drive is powered and active?
Green LEDs (LED1 and LED3) light when 12V power is ready for each U.2 port. Red LEDs (LED2 and LED4) blink to indicate drive activity, while red LEDs 11–23 stay off during normal PERST#, WAKE# and CLKREQ# states.
