16-pin 12VHPWR extension for RTX GPUs

This 3 ft cable connects a 16-pin (12+4) 12V-2x6 graphics-card connector to two 8-pin female PCIe plugs. It is intended for GeForce RTX 5070, 5070 Ti, 4090, 4080, 4070 Ti, 4070 (16-pin models only) and 3090 Ti cards that use the 12VHPWR interface. The sleeved 16 AWG tinned-copper wires are rated for up to 600 W.

600 W limit and dual 8-pin requirement

The extension supports a maximum of 600 W through the 12VHPWR standard. It must be fed by two separate 8-pin PCIe cables from the power supply; using only one connector can cause system damage. The cable cannot be plugged directly into a PSU port and adds 30 cm of working length between the PSU cables and the graphics card.

Check GPU connector and PSU cables before ordering

Verify that your graphics card uses a 16-pin (12+4) 12VHPWR socket — this cable will not fit 12-pin or 8-pin GPU power connectors such as those on the RTX 3090 or 8-pin RTX 4070. Also confirm that your power supply has two unused 8-pin PCIe outputs available for the female ends of this extender.

Questions about this item

Should I pick the 3 ft length or a different size?

This model is only offered in a 3 ft (34 cm including connectors) length, so there is no alternative size to choose.

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

The extension can safely deliver up to 600 W to a 16-pin GPU when both 8-pin PCIe connectors are plugged into the power supply.

Which PCIe standard does the 12VHPWR connector follow and what does that limit in practice?

The connector follows the PCIe 5.0 12VHPWR specification, capping power delivery at 600 W and requiring two 8-pin PCIe cables from the PSU.
