GPU Power & Cable Kits provide the supplemental power cabling and hardware required to connect high-wattage discrete graphics and compute accelerators to server and workstation power supplies. This category includes PCIe 8-pin to 16-pin (12VHPWR / 12V-2×6) adapter cables, multi-rail splitter harnesses, high-gauge sleeved extensions, and bundled connector assortments sized for specific GPU TDP classes—from 150 W mid-range cards up to 600 W flagship accelerators such as the NVIDIA RTX 4090 or H100 PCIe.

Primary buyers are system integrators building multi-GPU inference or training nodes, HPC facilities retrofitting existing PSUs for higher-wattage cards, and data-center operators standardizing cable inventories across heterogeneous GPU fleets. Key selection criteria include connector type (12VHPWR vs. dual 8-pin), wire gauge (16 AWG minimum recommended for ≥300 W loads), cable length relative to chassis depth, and whether the PSU is modular or fixed-rail—since splitter harnesses add amperage load per rail and must stay within the PSU manufacturer's per-connector current rating.
