Lenovo 4X97A81933 NVIDIA SW GPU Cable Kit
Overview
The Lenovo 4X97A81933 is a factory-new GPU cable kit engineered for NVIDIA GPU installations in compatible Lenovo ThinkSystem server platforms. GPU interconnect cabling is a mandatory physical component when adding or repositioning NVIDIA GPU cards in supported configurations — the 4X97A81933 supplies the correct-gauge, correct-keyed cable assembly to complete the installation without improvising with aftermarket alternatives that may not meet Lenovo's signal-integrity or mechanical retention specifications.
Compatibility
The 4X97A81933 is a Lenovo option part designated for specific NVIDIA GPU configurations in the ThinkSystem server family. Because GPU cable kits are chassis- and riser-geometry-specific, confirm the exact target server model and GPU slot configuration against Lenovo's ServerProven or the product's configuration guide before ordering. Installing an incompatible cable assembly can prevent GPU seating, violate airflow requirements, or leave PCIe auxiliary power connections unmet — any of which will prevent the GPU from initializing.
Installation Notes
Route the cable assembly according to the server's hardware maintenance manual to avoid contact with rotating fans or sharp chassis edges. Verify that the GPU auxiliary power connector clicks fully into the card before powering on — partial engagement is the most common field error with GPU power cables. If the target system uses tool-less riser assemblies, seat the cable before locking the riser into its chassis guides. Confirm firmware and device-driver compatibility with the specific NVIDIA GPU model after physical installation is complete.
