PCIe Gen4 gender changer for RTX 3080
The Innocard DP7401 adapts a PCI Express 4.0 x16 slot to dual SlimSAS 8i ports. It is built for rack servers that need to connect an NVIDIA GeForce RTX 3080 GPU through a cable-based topology. The card includes a ReDriver and clock buffer to maintain signal integrity across longer traces.
Thermals noise and power draw
The adapter is a passive add-in card with no fan or active cooling of its own. It draws auxiliary power through the slot and the onboard buffers to sustain 16 GT/s links over extended cable runs. Operating temperature and acoustic profile depend entirely on the host chassis airflow.
Bundled accessories and software
No driver disc or management utility is included; the board relies on native OS support from Windows 7 through Windows 10 and UEFI 2.3.1 or later. A green D1 LED indicates when the AIC is powered and ready. The ReDriver and bus buffers enable longer cable lengths without extra configuration.

Questions about this item
How do I install the Innocard DP7401 and what step is often missed?
Insert the card into a PCIe 4.0 x16 slot, connect SlimSAS 8i cables to the SFF-8654 ports, then enable bifurcation in the UEFI 2.3.1 BIOS so the 16 lanes split into four x4 links; skipping the bifurcation setting leaves drives invisible.
What maintenance or replacement will the Innocard DP7401 need later?
The on-board ReDriver, clock buffer and bus buffers are soldered components with no user-serviceable parts; if signal integrity degrades over time the whole adapter must be replaced.
What limit appears first when the Innocard DP7401 runs sustained workloads?
The 16 GT/s PCIe 4.0 link budget and the ReDriver equalisation range set the maximum cable length and trace distance; exceeding them causes link errors before any thermal throttle.
