12V-2x6 PCIe 5.0 Extension for RTX 40 Series

This Vszerda extension cable connects a 16-pin (12+4) 12V-2x6 male plug to two 8-pin (6+2) female sockets. It is built for GeForce RTX 4090, 4080, 4070 Ti and 3090 Ti graphics cards that use the PCIe 5.0 power connector. The 30 cm length adds reach between the power supply and the GPU while keeping the original cable in place.

Installation notes and common issues

The cable uses 16 AWG tinned copper wire and includes four transparent acrylic cable combs to keep the sleeved wires aligned. Route the combs after connecting both ends so the sheaths sit flat. Do not force the 16-pin connector if it resists; check pin alignment first. The two unused holes on each 8-pin female are ground positions and do not affect operation.

600 W power delivery limit

This extension is rated for up to 600 W output, matching the PCIe 5.0 specification for the 12V-2x6 interface. It will not fit cards that retain a 12-pin or standard 8-pin power input such as the RTX 3090 or 8-pin RTX 4070 models. Builders needing higher wattage for RTX 50 series cards should use a native 3x8-pin cable instead.

Questions about this item

How can I verify the 16-pin 12V-2x6 connector is seated correctly and delivering up to 600W after installation?

Check that the 12+4 male plug clicks fully into the GPU socket and both 6+2 female ends lock onto the PSU cables; the 16AWG tinned copper wires and four acrylic combs keep the 30 cm run tidy so you can confirm a firm connection visually.

What ships in the package and which items must be sourced separately?

The box contains one 30 cm white sleeved extension cable with a 16-pin male to dual 8-pin female layout plus four transparent cable combs; you still need your PSU’s native 8-pin PCIe cables and a compatible RTX 4090, 4080, 4070 Ti or 3090 Ti graphics card.

Which version should I choose for an RTX 4080 versus an RTX 3090 Ti?

This single 12V-2x6 PCIe 5.0 extension works for both the RTX 4080 and RTX 3090 Ti because each uses a 16-pin 12+4 connector; it will not fit cards with a 12-pin or 8-pin socket such as the RTX 3080 or 8-pin RTX 4070.
