StarTech PCIEPOWEXT 8-inch 6-pin PCI Express Power Extension
StarTech.com manufacturer part PCIEPOWEXT. This record documents only this specified cable assembly; connector fit is not evidence of a matching pinout or PSU compatibility.
PSU SAFETY: Modular PSU-side cable pinouts are proprietary and model-family-specific. Never substitute a modular cable by brand, connector fit, color, or appearance; use only the exact PSU maker-approved cable for the exact PSU model and revision.
Manufacturer specifications
| Manufacturer part | StarTech.com PCIEPOWEXT |
|---|---|
| Connector / pin count | One 6-pin PCI Express power plug to one 6-pin PCI Express power receptacle. |
| Wire gauge / length | 18 AWG; 8 in (203.2 mm). |
| Compatible PSU family | A standard native 6-pin PCIe GPU power connector on the PSU’s supplied PCIe lead, for an add-in card with a 6-pin input. On modular PSUs use only the exact PSU-approved original cable; this is an extension, not a replacement modular cable or a conversion to 8-pin. |
Power and safety caveats
Preserves the six-pin PCIe connection; it does not raise the PSU/cable current limit or authorize an adapter. Use a GPU’s native connector requirements and PSU manufacturer wiring. Fully seat both ends and discontinue use if contacts discolor or overheat.
Case clearance and routing
Adds an 8 in cable body. Measure the GPU route and connector bend allowance, avoid pulling sideways on the card socket, and keep the extension away from fan blades, sharp edges, and panel pressure.
