12VHPWR Extension for Dual 8-Pin GPUs

This Lian-Li extension cable converts a native 12VHPWR or 12V-2x6 power-supply output into two standard 8-pin PCIe connectors. It is built for graphics cards that still use dual 8-pin power inputs such as the RTX 3060, 3070, 3070 Ti, 3080, 4060 or 4070. The 16-pin female end plugs directly into the PSU cable while the two 6+2 male ends feed the GPU.

PCIe 5.0 and ATX 3.0/3.1 Interface Limits

The cable is rated for the PCIe 5.0 specification and supports ATX 3.0 and 3.1 power supplies with a native 12VHPWR output. It uses 16 AWG tinned copper wire rated at 300 V and 10 A per pin. The design is not compatible with graphics cards that have a 12+4 pin connector such as the RTX 4070 Ti Super or RTX 5070, so those GPUs cannot use this adapter.

600 W Capacity and 20 cm Reach

Maximum power delivery is 600 watts, which covers the typical draw of supported dual 8-pin cards. The 20 cm length provides enough slack for tidy routing inside most cases without excessive cable bulk. Builders needing to power a 12+4 pin GPU or requiring a longer run to reach distant connectors will need a different solution.

Questions about this item

Should I pick the 3 ft or the shorter 20 cm version for my build?

The 3 ft length gives extra routing room behind the motherboard tray and suits larger cases, while the 20 cm version keeps cable clutter minimal in compact builds.

What does the 600 W rating mean once the cable is installed in my system?

It confirms the 16 AWG tinned copper wires can deliver up to 600 W continuously to a dual 8 pin graphics card without exceeding the 10 A per pin limit.

How does the PCIe 5.0 / ATX 3.0–3.1 interface cap real-world power delivery?

The 12VHPWR female end follows the 12V-2x6 spec used by ATX 3.0 and 3.1 power supplies, so the 600 W ceiling is enforced by the connector standard itself.
