Aukuoy 12VHPWR Cable Extension 16 Pin(12+4) Female to Dual PCIe 8 Pin(6+2) Male 6.8 in Computer Power Cord

12VHPWR Extension Cable for GPU Power

This 16-pin female to dual 8-pin male conversion cable connects a power supply's native 12VHPWR output to graphics cards that use traditional PCIe power connectors. It measures 6.8 inches long and uses 16AWG copper wire rated for up to 600W delivery. The adapter targets builders upgrading a GPU without replacing an ATX 3.0 or 3.1 power supply.

Dual 8-Pin Connectors Enable Legacy GPU Support

The dual 6+2 pin male ends plug directly into cards such as the RTX 3060, 3070, 3080, 4060 and 4070. This arrangement splits the single 12VHPWR source into two standard PCIe feeds, allowing older high-end models to draw power from modern ATX 3.0 units like the Corsair SF1000L or Seasonic Focus GX series. The cable is not a modular PSU replacement; it only extends the existing 12VHPWR lead.

Not Compatible With Native 12VHPWR Graphics Cards

GPUs equipped with a 12+4 pin connector, including the RTX 4070 Ti Super and RTX 5070, cannot use this adapter because they require the 12VHPWR interface directly. The 17 cm length also limits routing options in larger chassis, so builders needing longer reach or native 12VHPWR GPU support must choose a different solution.
