12VHPWR Extension for RTX 40 Series

This 16-pin male to triple 8-pin extension cable is built for PCIe 5.0 graphics cards such as the RTX 4070 Ti, 4080 and 3090 Ti. It connects the 12VHPWR socket on the GPU to three standard PCIe 8-pin cables from the power supply. The product is an extension only and must not be plugged directly into the PSU. It is not compatible with the 12-pin connector found on RTX 30 series cards.

Practical limits of the PCIe 5.0 12VHPWR interface

The connector is rated for up to 600 W delivery through 16 AWG tinned copper conductors and alloy copper terminals. A power supply of 1000 W or more is generally required to support the graphics cards this cable serves. The extension adds length between the PSU cables and the GPU socket, so total cable run and routing space inside the case become the limiting factors for installation.

Build quality and daily implications

Each wire is individually sleeved and ships with pre-installed cable combs that keep the bundle aligned and reduce strain on the 16-pin plug. The black sleeve gives a uniform look that suits dark-themed builds. Because the combs hold fixed spacing, the cable resists sag and maintains a tidy profile behind the motherboard tray or along the GPU backplate.

Questions about this item

Should I pick the 16AWG 12VHPWR extension for my RTX 4080 or a different gauge?

The cable uses 16AWG tinned copper rated for 600W maximum output, matching the 12VHPWR PCIe 5.0 connector on RTX 40 series cards.

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

It guarantees stable power delivery up to 600W through the 12VHPWR male plug to three 8‑pin connectors, preventing frame drops or flicker under heavy GPU load.

Does the PCIe 5.0 12VHPWR interface limit the power I can draw from my PSU?

The 12VHPWR PCIe 5.0 plug supports up to 600W; the maker recommends a 1000W or larger PSU for RTX 4080, 4070 Ti or 3090 Ti configurations.
