NVIDIA's full name for this card is "NVIDIA RTX PRO 4000 Blackwell SFF Edition". The datasheet gives the system interface as PCIe 5.0 x8 and footnotes it "Uses full-length PCIe interface", meaning a physically full-length x16 edge connector wired for eight lanes; pcie_lanes here records the eight electrical lanes. No power connector is listed, because the whole board runs inside the 75 W the slot supplies.

Overview

The NVIDIA RTX PRO 4000 Blackwell SFF Edition puts 8,960 CUDA cores and 24 GB of GDDR7 with ECC into a half-height, 70 W card that needs no supplementary power. It is the same core count as the full-height RTX PRO 4000 Blackwell, clocked down hard: 24 TFLOPS of FP32 and 385 dense TFLOPS of FP4, on a 192-bit bus running at 432 GB/s rather than 672 GB/s. That is the trade for fitting a modern professional GPU into a small form factor desktop or a 1U edge box. For inference the 24 GB of ECC memory at 70 W is the appeal, because performance per watt on this card is the best in the RTX PRO Blackwell desktop line by a wide margin. Display output is four Mini DisplayPort 2.1b connectors.
